Does Keratin Make Hair Straight?

One of the newest crazes in the beauty industry are keratin straightening or smoothing treatments. These processes take kinky, curly or frizzy hair and make it smooth and soft or straight depending on the treatment used. Women all over the world have tried this out and found that even the most hard-to-tame hair can be made soft, silky and manageable.

Wow, can keratin really do that?

Smooth and silky? Sure! But straight? Definitely not.

Remember, keratin is a natural protein that makes up most of your hair. The properties of keratin are amazing in that they can refresh dryness and damage, but if your hair is naturally curly, there is nothing keratin proteins could do to change that.

So what’s the deal with ‘keratin straightening’? To answer this, we need to get into the structural difference between straight and curly hair and exactly how chemical straightening works.

First, what causes curly hair?

To put it simply: genetics. Your genes will determine how straight or curly your hair is. More specifically, your genetics determine the number of disulfide bonds you have within your hair proteins.

Wait, what?

See, every hair strand grows from a sac in the scalp called a follicle. In the follicle, keratin and other proteins are created. These eventually die and become the hair shaft (hair is made of dead protein cells being pushed out of the follicle by new, living cells).

The proteins in your hair contain sulphur atoms, which are called sulfides. When two sulfides bond (called a disulfide bond) they can create a bend in the hair fiber. Curly hair has a large number of bonded sulfides, while straight hair has very few.

How does chemical straightening work?

Chemical hair straightening works by breaking down those disulfide bonds in curly hair and resetting them so the hair is straight. This is done in three stages: relaxing, neutralizing and conditioning.
Depending on the treatment, the relaxing, neutralizing and conditioning agents may all be combined into one cocktail, and the hair may be set with a blow dryer or straightening iron, but these are the chemical components:
First the bonds need to be broken down. This is called ‘relaxing’ and is done with chemicals that contain alkalis (do you remember high school chemistry? Alkalis are basic so they denature proteins, meaning they change the way proteins fold over onto themselves).

These alkalis are designed to do a controlled amount of damage: just enough to break down the curls but not so much as to break the hair. The chemical is washed off when the desired amount of damage is done.

The second step is to restore the pH balance of the hair. Since alkalis are basic, an acidic neutralizer will be put on to stop the chemical process and keep your hair from further breakage. At this point, the hair will be straight, but very delicate.

The final step is to apply a conditioner that will repair the hair damage and protect your hair from any additional damage.

So why is it called a ‘keratin straightening treatment’?

You might have guessed by now that the role keratin plays in this whole thing is the conditioning stage of straightening. New developments in keratin hair products mean that damage can be repaired more completely than it has been in the past. Not that it’s a great idea to abuse your hair, but keratin does allow it to recover from some pretty harsh treatments.
What this translates to in the world of hair straightening is the opportunity to use stronger chemicals to break down the sulfide bonds. Formaldehyde, for instance, is occasionally used as an ingredient in the relaxer. The aggressive chemicals allow hair to be straighter for longer and the use of keratin can counteract any damage (though there have been reports of salons overdoing it with the relaxer and serious hair damage as a result—only get this treatment done at a reputable salon).

So while keratin is a major component of a ‘keratin straightening treatment’, it shouldn’t be confused for a straightening agent. The role keratin plays in a keratin straightening system is a positive one by conditioning and strengthening and reversing damaged hair.

As for why the term ‘keratin straightening’ gained popularity, I can only guess that it was for marketing purposes… ‘formaldehyde straightening treatment’ doesn’t have quite the same appeal.

    Thanks so much for this information, and although you seem to have answered everything I still have ONE more question for clarity… OK. I am african american and I have natural hair. My hairdresser said that se has a keratin treatment that DOES NOT have formaldehyde (Keratin Brazilian treatment)and it only last a few weeks and the hair reverts back to it’s natural state. Is this possible? I love my natural hair, but would also like to de-frizz for a few months as an option. Will this permanently change the texture of my hair?

    • Keratin Questions on

      It is possible that the hairdresser has a system that does not contain formaldehyde, however, the effectiveness of this treatment and how long it would last would depend on the system and what technology it uses. What system does your hairdresser use?

  2. J on

    This is incredibly thorough info. Thank you for breaking down the science of so much. My hair is curly and a long while back I used to brush with a protein shampoo and it seemed to loosen the curl a great deal so I stopped using it, thinking I was temporarily perming my hair. Now going back to it, I think what it is really doing is eliminating frizz entirely, by making every single hair behave like they should, as opposed to only certain areas. What is your take on this?

    • Keratin Questions on

      It is very unlikely that a shampoo would be causing any perm processes on your hair, so you do not need to be concerned about that. Protein shampoos will certainly help, and potentially bind well and help align proteins within your hair. However, it depends on what type of proteins. The ones containing keratin are much more effective that the ones with hydrolyzed wheat, soy or other vegetable proteins in as it is much more effective to fix like with like. Also, there are many other components to the formulation that will help with frizz. Frizz is often most related to how moisture comes in and out of your hair, so products that help maintain the moisture balance in your hair are helpful. Without more information on the products you were using it is hard to say what would be having the biggest effect on your frizz control, but regardless of other things, a protein rich shampoo will be helping.

      • Keratin Questions on

        African American hair is damaged by chemical and physical treatment in the same way as any other hair type. Relaxers are often caustic and these are particularly damaging to hair, causing it to become weak and brittle. Unfortunately the same process that makes relaxers work also damages the protein that the hair is made from. The particular proteins in Keraplast Hair Rescue with Replicine Functional Keratin bind to damaged protein in the hair, zipping together like teeth in a zipper, to repair that damage. Many other products will coat the hair, provide a short term shine, or try and cover up the damage temporarily. To genuinely repair the hair intact keratin proteins are needed to bind to the damaged keratin inside the hair. Keraplast Hair Rescue is the best way to deliver these intact proteins to your hair. It is still a fairly new product and only the most innovative salons are using it. Talk to your local salon about trying a treatment.

  3. Shannon on

    I had done a home keratin treatment and it did NOTHING unless I used a blow dryer — with the dryer, my hair was straight and silky, and without it, my hair reverted to its natural texture and wave. But a friend offered to do a salon treatment on me as a gift (she’s a stylist, obviously:) Do the salon “keratin straightening” treatments leave hair straight even after air drying — I prefer to air dry because of time — or will I have to use the dryer?

    • Keratin Questions on

      We are not aware of a current home based system that gives sustained straightening. The change required in the hair to make it stay straight is quite difficult to achieve in a durable way that doesn’t revert back to natural curl quickly, and heat helps this process a lot. Having a process done in a salon means that heat can be applied in a controlled way by an expert. This is important because too much heat damages your hair, and too little makes the process not as effective. In answer to your question, some salon systems do create straight hair that is sustained. However, you have to look at each system on a case by case basis. They use different technologies to achieve the effect and you have to consider your hair type, treatment history, and safety concerns of the ingredients being used in the system.

  4. Laura on

    Chemical straightening is bad no matter what you do. After you get this done your hair will never be the same again! It’s much safer to use a treatment that has keratin which is naturally present in healthy hair. The Cocoa Keratin System is the best I’ve used so far and it doesn’t damage hair at all, it even comes with its own pre and post shampoo + conditioner. Very complete and it lasts for 5 months 🙂

  5. Veronica on

    I have curly hair and I want it to be straight without having ti straighten it so what’s the best thing I should do?

    • Keratin Questions on

      Making curly hair straight in a temporary way can be achieved with styling, simply the use of heat, water (blowdrying it straight) and using styling products depending how curly your hair is. Unfortunately in order to have any durable effect that will last more than a few hours or a humid day then you will need to look at straightening products and systems, either at home or in a salon depending on your budget and desired outcome.

  6. Tricia on

    I thought keratin was just a protein to condition hair until I started hearing about the use in straightening. I recently bought nunaat Brazilian keratin intensive hair mask. My aunt does a Brazilian treatment to straighten her hair and now I’m nervous that this product may do the same. I’m supposed to leave it on for 15 minutes then rinse. PLEASE tell me that this is just a conditioner. I love my natural curly hair and really just want a deep conditioner for moisture and better hair health.

    • Keratin Questions on

      The main use of keratin is to repair and condition hair. The various keratin treatments that claim to be straightening are using other chemicals to achieve the straightening effect, not the keratin. The nunaat Brazilian keratin intensive hair mask you describe does not straighten, it is designed as a deep conditioner and moisturizer, so you should be fine. However, please don’t be fooled by the label on the product. It claims to be a keratin treatment but you will see from reading the label that there is no keratin in the product. There are several plant proteins (soy, corn and wheat protein), which will make your hair feel very nice, but there is no keratin so it will not offer genuine repair. For genuine repair from inside the hair fiber then an intensive treatment using Replicine Functional Keratin is the best option.

  7. S. Sugar on

    I am African American, I am in the process of growing out my chemical relaxer. I have very kinky hair. I would like to use a keratin treatment that will give me the option of wearing my hair straight but mostly curly. I mainly want to be able to manage my hair easily. It is very think, and sometimes unmanageable. What Keratin Treatment do you suggest that I look into, that will just soften my kinky curl to the point of a loose curl, with the option of adding the minimal amount of heat to straighten?

    Thank you

    • Keratin Questions on

      This based straightening systems may be best for the loosening of the curl that you describe. The recent developments with these straightening systems have improved them substantially from several years ago. This one from Keune contains particular keratins known to strengthen hair well which should also help with recovery from relaxers. Replicine Functional Keratin in the form Hair Rescue, available in some US salons, will also help with additional strengthening and repair.

  8. Sarah Jo on

    Hi, I was interested in getting the keratin treatment done but I had a couple questions. Does the treatment make you loose more hair? Will it cause a loss of volume or body in my curly hair? I have thin hair with curls of all sizes that i love and don’t want to ruin. I wanted to lose the crazy frizz without messing with the body or volume of my hair. Will it weigh down my hair?

    • Keratin Questions on

      I think you must be referring to a keratin straightening or smoothing treatment. The outcomes really depend on the system used and the skill of the person doing them. The systems that use formaldehyde can make hair weaker and break more easily. If you want to keep some curls and volume then I don’t think that most of the straightening or smoothing treatments in salons will be what you want, they will be more likely to take all of your curls away.

  9. Xavier on

    I am African American and I have a friend who’s also African American and she had small tight curls to began with and after using the treatment her hair came out with a really loose curl pattern and hair texture changed and became soft and silky and it looks really good how did this happen? And will my hair possibly come out the same way?

    • Keratin Questions on

      I think you must be referring to a keratin straightening or smoothing treatment. The outcomes really depend on the system used and the skill of the person doing them. There are many, many different systems that use very different approaches to making hair less curly. Be sure to check what system your friend used and for safety reasons make sure it doesn’t contain formaldehyde.

    • Keratin Questions on

      Hi Rafif, please tell us more about what your need is. Keratin products can be used for many things, including straightening and repair. The most proper use is to repair hair damage, if the correct keratin is applied then it can rebuild the damaged keratin structure inside the hair. Replicine Functional Keratin is best for this purpose.

  11. Dolly on

    For the past two years I had my hair straightened at the salon, using a keratin product. It was great! No goofy waves in the wrong place! This year, when I had it done, the stylist used the 3 day one, that you go home and wait 3 days before shampooing. Two weeks later, I realized that it had not worked as it had over the past two years. My stylist redid the treatment, using another Keratin product. It is still not right. Why is nothing working this year?

    • Keratin Questions on

      There are quite a few different straightening and smoothing systems available, and these work by different mechanisms to straighten or smooth your hair.
      The three traditional mechanisms that are used to straighten hair are:
      • A crosslinker, such as formaldehyde, which forms permanent bonds between specific amino acids in the proteins of your hair. This mechanism is the basis of many Salon keratin products including Keratin Complex Smoothing Therapy by Coppola, Global Keratin Complex, the La-Brasiliana treatment, Brazilian Keratin Treatment, the Brazilian Blowout, and Brazilian Hair Straightening.
      • A reducing agent, such as thioglycollate or thiosulfate, which opens the natural cysteine crosslinks in your hair and allows them to reform in a different configuration. This mechanism is the basis of the Japanese yuko system and the Anevolve system as well as a number of others.
      • Relaxers which are caustic and can hydrolyse (break) the protein chains in your hair as well as irreversibly convert the cysteine crosslinks so that they can no longer reform bridges between the proteins. These weaken your hair, so that it is less able to hold a curl, but it can also become quite fragile.
      There are also some new system out on the market such as the Kerastraight system, the K –Pak thio-free wave by and the Bio-ionic hair straightening system which use other processes.

      Reducing agent based systems are also the most common process used in a perm.

      Unfortunately not all of these different treatments are compatible and they are not necessarily compatible with other processes that you may have had done on your hair. Some dyes may interfere with the straightening process and also some shampoos which contain cross-linkers may interfere, such as those used to that help to rebuild hair by creating crosslinks. Products that work this way include Biolage Advanced Keratindose shampoo.
      Another cause of less than satisfactory results is simply that the concentration of the straightening agent is not sufficient to deal with the strength of the curl in your hair. African hair has very strong curls and needs a higher concentration of straightening agents than European hair.

      Until last year the formaldehyde based systems were very popular. However, concerns were raised about the safety of these systems due to the toxic nature of the formaldehyde used. As a result, the use of the formaldehyde based systems has become much less popular. Some of the alternative systems have not been as well proven and may be less effective. Your stylist may have switched from a formaldehyde based system to another system that is not as effective.

  12. Samara on

    Hi. I’m mostly east-indian but mixed with caucasian and african as well. I have very course, stubborn, curly/wavy hair that I have been relaxing for the past four years. After my pregnancy, even the relaxer could not straighten my hair. I tried a well-reputed salon keratin smoothening system but that seemed to make things worse and my scalp started badly flaking. I want straight, but healthy hair. My hairdresser has recommended using another very expensive keratin treatment with the hope of straightening my hair. I did not know that keratin does not straighten. Should I relax to get straight hair and then use the keratin?

    • Keratin Questions on

      Hi Samara

      It does sound as though you need a quite aggressive treatment to straighten your hair- such as relaxation. But be aware that the relaxation process can be quite damaging to your hair, so having a Hair Rescue Treatment with Replicine Functional Keratin, after the relaxation will help to avoid a lot of hair fiber breakage. Pregnancy can place a lot of stress on a woman’s body often causing a lot of hair loss so your hair may be more susceptible to damage than it would have been previously.

  13. Megan on

    Hey I have thick hair I’m wondering if getting a Keratin treatment would make it naturaly straight?

    • Keratin Questions on

      Hi Megan
      There are a lot of straightening treatments out there that are now called “keratin treatments”. Most of these are not all “natural”. Keratin on its own will not straighten hair, but keratin in a straightening treatment does help with the damage that a straightening treatment does. For more details on this – see our article on the page
      Straightening treatments can certainly make your hair straight if the treatment is well matched to the curliness of your hair. Wavy Caucasian hair is relatively easily to straighten while curly Afro-American hair is quite resistant to being straightened. This is why a hair relaxation process is more often used with Afro-American hair, which is quite an aggressive treatment. A good stylist should be able to advise you on what sort of straightening treatment would be best and most effective for your hair.
      In a previous response I have discussed the different straightening system in a bit more detail – see Keratinquestions’ response on June 10th 2013. Just to add to this discussion, I should also point out that some formaldehyde-free treatments still contain an aldehyde- it’s just not formaldehyde, so the process (and the issues) are still pretty much the same!

  14. Theresa on

    does your hair have to be fully natural before you can get a keratin treatment?

    • RobKelly on

      Your hair doesn’t have to be fully natural before getting a “Keratin” straightening treatment. However some Keratin straightening treatments don’t work well together, so if you had had one done previously, it is advisable to know what the active ingredient is in the treatment that you have had and ask the advice of your stylist before getting another one done. For more information on the different straightening systems see Keratinquestions response on June 10th 2013 on page .

      It will help to avoid problems if you have grown out any previous treatments including bleaching perming or straightening. All such treatments will damage your hair to some extent and having one treatment on top of another will cause even more damage. If you have fine hair, this can lead to hair that breaks easily when combed.

    i am indian – american and have long curly brown hair, its quite strange actually but i have been told by several stylists that people perm their hair to get it like mine…however, i have had some serious difficulty maintaining my hair as it is quite frizzy. I am planning on doing the keratin complex infusion therapy deep conditioner and i have a few questions! for starters, i do not want my hair to become dead straight, i just want it to become less frizzy, smoother and silkier, is this possible? secondly, i wanted to know if by the time the treatment wears off, will the top of my hair become frizzy and the bottom silky; like, one of those weird hairstyles where the top is frizzy and then you have to wait a while for it to grow out? lastly, after the treatment wears off will my hair go back to the way it was?- because, to be quite frank. i like my curls and ringlets!
    i am going to the hair salon tomorrow and i am sitting there for 5 hours and i would just like to be certain that this will give me the outcome i am expecting !
    thanks x

    • Keratin Questions on

      Hi Tanya

      Thanks for your email. You hair sounds lovely and I can appreciate that you certainly won’t want to do anything that detracts from its appearance. It does sound as though the main issue that you have with it is the frizziness on top?

      I take it that the keratin complex infusion therapy deep conditioner that you have arranged is a salon Coppola Keratin Complex smoothing treatment followed by the use of the Deep conditioner? There are a number of “Keratin treatments” available and they can be quite different in their results. Are you confident that you know all the information of what smoothing agents they would be using on your hair?

      The Coppola Keratin Complex Smoothing treatment is a smoothing system that can be used to straighten your hair temporarily. It doesn’t use chemicals that would break the bonds in your hair Even so, the effect will last about 3-5 months and the process uses flat irons at a fairly high temperature of 400-430oF which will have a long term effect on your curls.

      The conditioner has received some great reviews but it is a product that you will need to keep using at home to achieve the full benefit. However I would like to point out that while this formulation contains some nice ingredients such as Planifolia Fruit Extract hydrolyzed soy proteins and hydrolyzed wheat protein it doesn’t include any keratin in it, so you would not be receiving the benefits of keratins or, in particular Replicine™ Functional Keratin®, in your regular hair care regime.

      If all you want is to reduce the amount of frizziness and curls, and before going to the expense of having a full salon treatment, have you considered using home products such as combining the Coppola Keratin complex infusion with the deep conditioner, to see if the benefits from using these at home will give you the improvement that you would like to see? If you avoid using the irons and use a hair dryer to seal the keratin treatment you may find that you are able to keep your curls, while still improving the condition of your hair.

      Of course if a smoothing or straightening system, temporary or otherwise, is definitely not what you are after then a hair repair treatment may be better for you. Hair rescue treatment with Replicine™ Functional Keratin® is one such treatment that provides keratin to strengthen and repair your hair! To continue ot be able to apply Keratins in your regular hair care regime there are a number of keratin containing shampoos and conditioners. These include the Paul Mitchell Awapuhi wild ginger range, BHave in Australia which contains the new active Replicine™ , and Keraplast has just brought out its own Intensive treatment shampoo and conditioner with Replicine™ Functional Keratin, available in the USA.

      Hi Tanya did you finally get the treatment done? I have similar hair like yours and I am Indian too. I don’t want to let go of my natural waves but need to reduce the frizziness. And I don’t want the top of my crown growing the weird wavey hair while the bottom is silky. Kindly help.

      Hi Jenn,

      Sorry Jenn, I’m not familiar with the cellophane treatment. Be careful of what is being sold to you as a “Keratin Treatment” as this term is also used to describe keratin straightening treatments. If your hair is already damaged, a keratin straightening treatment won’t help it at all. A keratin-based repair treatment that is available in most parts of the globe is the Awapuhi Wild Ginger Keratriplex treatment. BHave is a range currently sold only in Australia, which has a great Hair Rescue Product with Replicine™ Functional Keratin®. Keraplast also has a Hair Rescue Treatment with Replicine Functional Keratin that is available at Visible changes salons within the USA.

  18. haitham on

    can keratin apply on men hair? …and is keratin with formaldehyde can straighten hair? thanks

    • Keratin Questions on

      Hi Haitham,
      Definitely Keratin can be applied to men’s hair! It’s a great natural ingredient for all hair types and genders. And definitely formaldehyde will straighten hair. The Keratin in a straightening system will help protect your hair against the damage that happens during the straightening process. If you are continuing to use irons at home, a shampoo and conditioner with Keratin will also help to protect your hair against further damage. Look for shampoos and conditioners that contain the ingredients “keratin” and “oxidized Keratin”, not just “hydrolyzed keratin” as these will confer greater benefits in terms of hair strength, volume and condition.
      Take-home shampoo and conditioner products that include the mix Keratin, Hydrolyzed Keratin and Oxidized keratin for maintaining good hair health include Keune’s Careline Keratin Smoothing products, the Awapuhi Wild Ginger range, BHAVE‘s products and Keraplast’s Intensive treatment shampoo and conditioner with Replicine Functional Keratin. When you see the Replicine® Functional Keratin® logos you can be sure that the keratin ingredients are included at active levels to achieve the claims that are made for Replicine Functional Keratin.

  19. These sound good, especially the treatment. I’m always on the lookout for strengthening and repairing haircare.

    • Keratin Questions on

      There are lots of hair products labeled “Keratin….”. Only some of them contain any type of keratin at all and those that do usually contain only Hydrolyzed Keratin. The ones mentioned on this web site are the only ones that contain intact Keratin molecules that have measured benefits for your hair. These include the Awapuhi Wild Ginger range, The BHAVE range, the Keune Careline Keratin smoothing product and the Keraplast products.

  21. CherylG on

    I have seen a new crop of straighteing treatments that say they are free from formeldeyhyde and use amino acids. I am researching some of these. Is this just a remarket of the same Kertain Based hair straightening treatments. Examples are Design Essentials -Cysteine Amino Acid it says is used to elongate the hair.

    • Keratin Questions on

      Hi Cheryl,
      I haven’t been able to find out very much about the Design Essentials ingredients – at least those in the salon based professional products. So I can’t be definite about what process they are using.
      However, if the formulation includes cysteine, this will act as a reducing agent to open up the natural sulfur-based crosslinking agents in the hair. By using cysteine in the treatment process, some of the cross-linked protein cystine sites become blocked by the cysteine attaching to one side of the opened link. This prevents the site from reforming crosslinks at the end of the treatment. This will have the effect of softening curls. The amount of cysteine included in the formulation will determine the extent to which the hair is smoothed or straightened. Having a hot iron step in the process will also add to the degree of straightening that occurs.
      If the formulation includes thio (ammonium thioglycollate) as well as cysteine, the thio will work synergistically with the Cysteine to open up the crosslinks, with the cysteine also acting as a blocking agent to prevent re-crosslinking, as described above.
      Using a reducing agent such as cysteine or thio is one of the variations of what is the basis of the Japanese straightening system. In contrast, using formaldehyde (or gluteraldehyde or hydantoin) is the basis of the Brazilian straightening system.
      These two systems, along with lye based relaxations systems, are the main ways by which hair can be permanently, chemically altered to straighten it. There are a few unusual ones but the majority of treatments are based on variations of these three processes.
      I can’t say whether or not the Design Essentials formulations contain any keratin in them. There are a number of straightening systems called Keratin straightening treatment simply because they treat your hair – which is KERATIN!
      However amino acids and peptides in a formulation will help to draw water into the hair fiber and oils in the formulation will help to condition your hair.

  22. Hazel on


    • Keratin Questions on

      Hi Hazel,
      Sorry – I’m not sure what you mean by sulfur. The ammonium thiogylcolate which is in many perms formulations has a smelly sulfur like odor. Some systems also use thiosulfite while a few use cysteine as a crosslinking agent. These are all sulfur based chemicals that reduce and alter the existing sulfur-based crosslinks in your hair. In contrast, a Brazilian treatment is a formaldeyde based crosslinking formulation and the sulfur based systems are not very compatible with this.
      There are also shampoos that contain sulfur based surfactants such as Sodium Lauryl sulfate (SLS) and Sodium Lauroyl ether sulfate (SLES). These are quite strong surfactants found in clarifying and the more inexpensive shampoos. Some people find these ingredients to be irritating to their scalp but they won’t affect your Brazilian straightening treatment.

      There are a lot of mis-information and misconceptions out there. Any Keratin in a straightening system has nothing to do with the straightening effect. It is added into those treatments as a type of conditioner to help to minimize the damage of the straightening process on your hair – which is made of Keratin.
      Whether two straightening treatments are compatible with each other depends entirely on the straightening agents used. Typically a Brazilian straightening with formaldehye (or another aldehyde) is not compatible with a Japanese straightening treatment which uses some form of glycolate.
      In comparison, a Hair Rescue Treatment with Replicine™ Functional Keratin® has Keratin as its ONLY active – to repair your hair – no straightening, bleaching or relaxing chemicals. You can use this after any hair straightening treatment.

    Hi ! I’m a 13 year old girl with thick 3b curls , and I have been thinking about getting the keratin treatment for while now , so I think I might get it ! Except the lady at the salon that I go to said that my hair would be straight for 2 months !!!! By the way on their website they call it the keratin complex smoothing therapy. is that the same thing as the keritan treatment? When I researched how long your hair should be straight when you the keratin treatment most girls only had their hair straight for 3 days , or 72 hours . I’m confused . Does the lady at the salon I go to know what she’s doing ? Should I trust her with my hair ? Should I still get it ? I DON’T want my hair to get damaged or be ruined . I just want less frizz , and looser mangageble curls ! Please help me, and answer my questions . My appointment is in 5 days by the way .

      Hi Manina,

      I am sorry that it has taken a while to get back to you, and you may have already committed yourself to a straightening treatment. However you might find the following information useful for the future.

      The stylist is correct – many of the Keratin straightening treatments on the market are “permanent” or at least until your hair grows out- in that they permanently alter the structure of your hair. If you are simply looking for something that will reduce frizz and soften the curls then a “smoothing” system would be your best option. There are a few on the market and generally these are much less damaging to your hair than a straightening treatment. The straightening treatments will tend to damage your hair, at least to some extent, and that damage will be increased the more that you apply treatments such as straightening, perming, bleaching, ironing and coloring. Even using irons daily will tend to damage your hair. For many people the damage is not noticeable but with others – especially those with fine hair- this can result in split ends and fibers that break easily on combing.

      The good news is that there are products out there that can help restore your hair – and Keraplast’s Hair Rescue Treatment with Replicine™ Functional Keratin® is a great example of a salon-based treatment that can work wonders if you overdo the hair processing! Keraplast’s Hair Rescue Treatment, although not sold as a smoothing system, will also help with frizz and does help to soften curls a little.

    Does keration work with a thyroid condition cause I have one and I had my keration re done and hair drys and still frizzes after my shower. I thought its not suppose to frizz.

    • Keratin Questions on

      Hi Vicky,

      I’m sorry but without a bit more information on the Keratin (straightening?) treatment that you have had done I couldn’t comment on whether or not your thyroid condition will have an impact on the effectiveness of the Keratin treatment.

      Hair and skin changes are some of the symptoms that can be associated with thyroid problems. If your hair is affected by your thyroid condition a Keratin straightening treatment may only make it worse. A Keraplast Hair Rescue Treatment with Replicine™ Functional Keratin®, which is Not a straightening treatment, will help with the frizz as well as to improve conditions such as hair breakage and thinning hair.

      However treatment of the underlying condition is best managed by your doctor.

  26. Nadia on

    I have had a perm for about 8 or 9 months and it grew about 4 or 41/2 inches and I wanted to know if the Keratin Treatment will affect my new growth. I just wanted to know because I wanted to be prepared if I do need to grow it out again. Thanks.

    • Keratin Questions on

      Hi Nadia,
      It is confusing when there are Keratin Straightening treatments and Keratin Hair Rescue Treatments available. I am covering both options in responding to you:

      If you are planning to have a keratin based straightening treatment: This is a permanent treatment and how well it will interact with your existing perm, or a subsequent perm, will depend on the type of straightening treatment chemicals used. You stylist is best to advise you on this. Some straightening systems are quite incompatible with Perms.

      A Keratin Based Hair Rescue treatment is Not a hair straightening system and the effect that it has (volume increase, better shine and condition) will last up to 3 months. You can later have a perm or a straightening treatment after a Keratin Hair Rescue treatment without problems of non-compatibility.

  27. SARA on

    Hey ….

    i took keratin treatment few days before,and on that time,my hair was looking awesome and completely straight.but now,day by day its loosing its effects and my hair is going back its natural stage wavy and curly.Now,my hairdresser is ready to give me keratin treatment again, for better results.If i am going to take it again,so will it be harmful for my hair?i mean to say, is it ok to take it again so early??

    • Keratin Questions on

      Hi Sara,
      If it is a Keratin straightening treatment, doing another so soon after the previous one does not sound good. You should find out what the actives are in these treatments. They can contain quite harmful ingredients such as formaldehyde. Even a thioglycolate perming treatment is not something that should be done again so soon.

  28. Maria Andrade on

    Hi, I have thiny fizzy hair and also hair loss. My hairdresser recomended me to use a Brazilian Keratin she use in the salon. Should this treatment helps the fizzy and the hair loss. Please help me and answer my question, I have an appointment with my hairdresser for the Keratin treatment in 2 days. Thank you in advance. Maria

    • Keratin Questions on

      Hi Maria,
      A Brazilian Hair Straightening Treatment may help with the frizziness but certainly won’t help with the hair loss and may make it worse. A Hair Rescue Treatment with Replicine™ Functional Keratin® will go some way to helping with frizziness and will provide great benefits for your thin and fragile hair by strengthening the hair fibers and increasing your hair volume.

      To find a USA salon near you, you could try the Keraplast Salon locator at,com_storelocator/Itemid,76/view,map/.
      Hint: you need to put your zip code or city and state into the locator or, I find it easiest to start from the whole USA map. At this level you can see where the salons are across the country. Then you can zoom in on the area you want to look at.

      If there isn’t a salon nearby– you could ask your salon to contact Keraplast at and Keraplast would be happy to supply them the Hair Rescue Treatment and directions so that they can undertake the treatment with you.

    After care -How to keep treatment from coming out. Other than not to use sulfide products what else may inadvertently remove the straitening affect of keritin ? Can a mixture of mayonnaise egg and olive oil help or hurt a few weeks after getting keritan straiteni,g done in salon ? Could that mixture put curl back ?

    • Keratin Questions on

      Hi Kari,
      I would be surprised if a mix of mayonnaise, egg and olive oil hurt the effects of the straightening system if used at least a week after the straightening treatment. This mix will contain water, oils, egg proteins and citric or acetic acid. The actives in the straightening treatment will have locked into your hair and shouldn’t be dislodged by the components of this mixture.

      If you find that it helps to keep your hair in good condition then please let us know!

  30. susan woods on

    Fantastic website – so much information! Please could you advise me? I am due to have my hair straightened in 2 days with a product called Straightout keratin treatment. It contains formaldehyde. I am concerned about damaging my hair and particularly hair breakage from the hot irons. I live in New Zealand – unsure if this product is only available here.
    Many thanks in anticipation of your reply!

    • Keratin Questions on

      Hi Susan,

      Thanks for your questions and for your positive feedback! Sorry that it’s taken such a long while to come back to you. I have spent a bit of time finding out more about Straight-out Keratin and its ingredients.

      Thanks for the list that you sent; here’s the low-down:

      The recipe includes some good ingredients: Vitamin B5, olive fruit oil, Aloe vera (barbadensis leaf extract)coconut oil, sweet almond oil- all of which will help to condition your hair and protect it against the effects of the treatment and the formaldehyde in the treatment. The treatment does contain Formaldehyde which is considered toxic and an irritant. Regulatory agencies in the USA and EU have concerns over the use of formaldehyde in systems like this. As a general rule: if you get a treatment done you should ensure the salon is well ventilated to reduce health risks.

      I would have to say that this is one of the more unusually written ingredient lists that I have seen. There are international standards that New Zealand has also adopted that give the format as to how ingredients are written- and this certainly doesn’t comply. So I would not be confident that the position of the ingredients in the list gives an indication of the concentration that they are included in the formulation. For example, the position of formaldehyde at the end of the list would normally indicate that it is present at 1% or less.

      However it does list the trade name for the keratin that is included in the formulations which allows me to be able to tell you more than I would if it had simply been written as “Hydrolyzed Keratin”.

      Kerasol is the brand name for a hydrolyzed keratin ingredient made by a large international ingredient manufacturer called Croda. It is keratin that has been extracted from animal hooves and horns collected at the meatworks. It is made from the enzymatic breakdown of the keratin into quite large molecules (for the protein chemists; these are 100-120 kDa)and unusually large for a hydrolyzed keratin. The EU requirements are that hydrolyzed proteins contain much smaller molecules at less than a tenth the size (10 KDa). At the larger size the hydrolyzed keratin is too big to move into the structure of the fiber. It may be able to form films on the surface of the fiber and act as a protective layer and it will be able to penetrate damaged areas of fibers. But, through the extraction process most of the cysteine crosslinking sites will have been rendered inactive, so the ability for it to durably bind with your hair is limited.

      Just to give you a comparison: Replicine™ Functional Keratin® comprises Keratin extracted from shorn New Zealand wool, with no harm to the animals, and processed (in Lincoln) to give three general classes of protein:

      • “Keratin” which are the large separated out intact Intermediate filament proteins (80-100 KDa) that are responsible for making hair strong. They also have film forming properties and as a result of the specific extraction process used have retained their ability to re-crosslink so can form durable links with the protein in your hair.
      • Hydrolyzed Keratin which are very small molecules (in fact, much less than the EU 10KDa requirement) so are able to get into the crevices in your hair fibers. They also have retained their cysteine crosslinking capability through the extraction process used.
      • Oxidized Keratin, are medium- large sized molecules which can penetrate damaged and hair and bind to restore hair strength and condition, as a result of maintaining the integrity of the amino acids sequence needed to repair structure. They have been shown to be able to provide benefits to your hair and a great deal of benefit to your skin.

  31. Scarlett on

    My hair is pretty damaged from using heat over the years. My natural hair was very curly, but after straightening it for a while it damaged my hair. I cut it and grew it back out but absolutely HATED how tight my curls were. Since then, I’ve been blow drying my hair after showering and using the curling iron on it to give me my preferred loose curls. I know that using that everyday is not good for my hair at all but I hate my natural hair and am embarrassed to wear it like that in public.

    I don’t want to use the curling iron anymore because it’s damaging my hair even more. I was wondering if this treatment would loosen my curls and give it a better feel, so that I don’t have to always curl it. I’m afraid this will make it worse and I’m going to cut my hair as well, but was unsure if I should do this treatment.

    • Keratin Questions on

      Hi Scarlett,
      The Keraplast Hair Rescue Treatment with Replicine™ Functional Keratin® may loosen your curls a little but a better option may be to have a salon keratin smoothing treatment- which will have the straightening actives in the formulation but at lower levels than the straightening treatments. If your hair is quite damaged you could have a Keraplast Hair Rescue Treatment with Replicine™ Functional Keratin® after the smoothing treatment to give you strong yet loose curls that won’t require using an iron.

    hi,i hav done rebounding 2 years back and after one year i did coppola treatment,my natural hair is straight but i wanted to do more straightning hence did rebounding,now im out growing my hair,so when i did coppla first it was very good efect and lasted for 6 months n then again i did but second time it dint make my hair as straight as first time,as my hair has chemically treated and i have multiple blond n brown streak in hair and half of my hair is rebounded and half natural,im confused between cystine keratin and coppola treatment,plz help me which one is better product for my hair

    • Keratin Questions on

      Hi Farida,
      Your stylist is the best person to advise you on what treatment is best to use with your hair. The success or otherwise of any hair treatment will depend on your type of hair, the specifics of previous treatments that you have had, and what sort of condition your hair is in. He/She will also be able to look at the rebounded hair to see how similar or different it is to your own hair in terms of hair type (ethnicity) and condition.

      There are different types of straightening processes, containing different actives. Generally speaking those treatments that contain formaldehyde are less desirable than those that contain a cysteine crosslinking system, both from a health and safety perspective and with regards to the damage that is done to your hair by the treatment. The most well known Coppola products have previously used formaldehyde, however, the current Peter Coppola formulations claim to be both formaldehyde and aldehyde free.

  33. Rachel on

    Hi! I started using a keratin shampoo and conditioner to make my hair less frizzy and less crazy several months ago (I have since stopped a few weeks ago) In that time I was flat ironing my hair a few times a week for about 6 weeks, which I have also since stopped. My stylist commented, and I have also noticed, that my hair has suddenly become completely straight – no body at all, it can’t be styled with a big brush, diffused, nothing. I used to have wavy hair, and I still do on the top of my head (where the flat iron never went). Is it possible I gave myself a kind of home-style keratin treatment by accident? And if so, how long will it last? I really don’t like it – I want my wavy hair back! I dont know what to do…

    • Keratin Questions on

      Hi Rachel,

      Without knowing the brand of keratin shampoo and conditioner that you are using I can’t say what the likely effects they would have on your hair in combination with irons. Also without knowing the brand and product names, I can’t comment on whether or not the product actually has keratin in it. There are a number of marketing tricks that manufacturers can use to get the customer to think that the product includes keratin ingredients without it actually doing so. Be aware that some smoothing products available will have straightening agents in them.

      It does sound as though your hair has lost its curl and it is possible that this could be a permanent effect. This can happen simply because the hair has become too weak through the regular use of hot irons to sustain a curl. How susceptible your hair is to iron damage will depend on your hair type and what other treatments you have had done. For example, the combination of bleach and irons can be quite damaging to hair structure. You may be able to get some of the bounce back by using a deep conditioning masque. A more extreme remedy would be to have a soft perm added to your hair to gain some of the curl back while you wait for the effect of the hair products to grow out.

      A Hair Rescue Treatment with Replicine™ Functional Keratin® will help if you have issues with hair breakage, will help to boost volume, but won’t help with putting curl back into your hair.

  34. Hello,

    I permed my hair 8 months back and without much care, my perming is reducing now making my hair more dry. Will Keratin Smoothing make my hair straight. Will it damage my hair because of hair fall, thinning and frizzyness. I want to make my hair straight without undergoing straightening.

  36. Max on

    Hey thanks for the detailed explanation I just wanted to ask you about chemical straightening, it’s cheaper than keratin straightening so I’m guessing it’s not as good, I had it done once and my hair (medium length-curly/wavy) went perfectly straight but it was straight to one side and that was it, so for example if I tried to run my fingers through it to the other side they’d sorta stick there so I couldn’t style it or run my fingers through it I had to keep it straight to one side only.. Is keratin different? Will i be able to spike it or give it a messy look without it looking burned :/? Thanks again!!

    • Keratin Questions on

      Hi Max,
      There are a lot of different “keratin treatments” on the market with varying levels of straightening agent included. It sounds like what you want is a smoothing treatment- enough to smooth out your waves but not enough to make it board-straight. You stylist is the best person to advise on the best treatment for you taking into account the condition of your hair and your hair type.

  37. niki on

    I m from India,I have wavy but thin hair but I prefer it to b straight and wish to add volume to it…it would be very helpful if you could advice me if i should go for permanent straightening or keratin treatment..which would be long lasting and cause less damage to hair

    • Keratin Questions on

      Hi Nikki,
      I think that your stylist is the best person to advise you. I can suggest some points that may be useful for you to consider:

      With fine wavy hair you will not need a harsh straightening system to remove the curl. However all straightening systems will do at least some damage to your hair. A treatment with keratin especially if it contains more than just the “Hydrolyzed Keratin”, that is, but also includes “Keratin and/or “Oxidized keratin” will help to offset the damage. “Keratin” and “Oxidized Keratin” will also help to add volume to your hair. Smoothing systems are usually more gentle on your hair.

      Smoothing systems that contain these types of Keratin include:
      The bhave Keratin Smoothing Treatment
      Keune Care Line Treatment Keratin Smoothing

    Hey, this is one of the most helpful articles I’ve found ,thanx!
    I’m considering getting one next week but I still have questions;
    I have curly hair and would like to retain this curl, is this possible if I get this treatment?
    If so what is it called or do I just ask for a keratin conditioning treatment? Cause all I hear about is keratin straightening, and I’m scared to go and tell them I want to keep my curl and let them do it, because I’ve been to many “good” salon’s before getting different chemical treatments and asked about what things were and what they did and things have just come out the opposite of what I’m expecting. I have grown my hair out fully now but I need more than just a normal store bought at home treatment/ conditioner. Please Help Thanx

    • Keratin Questions on

      Hi Jodi,

      If you have a Hair Rescue Treatment with Replicine™ Functional Keratin® this will strengthen your hair fibers and add condition but it will not straighten your hair. Looking at your email address I’m guessing that you are in South Africa?

      These Hair rescue Keratin treatments are sold as part of the Keraplast and BHAVE ranges. The good news is that BHAVE is available in South Africa! You can contact their distributor there at (011) 887-0915 or skype 082 441 4378 to find a salon. Or if that fails you can ask BHAVE for a salon details directly their facebook page:

Similarly the conditioner contains some beneficial oils and extracts, Vitamin B5 (panthenol) and conditioning agents Behentrimonium Chloride and dimethicone; while glycerin which is a good moisturizer.

      No need to worry – there are no ingredients listed here that will take the curls out of your hair and a number of ingredients that are very beneficial and will help to control frizziness.

    Help! I had a kerastraight treatment performed by toni and guy in uk. I was given kerastraight shampoo and conditioner to use afterwards. The first couple of times i washed it, it smelled funny (musty/ eggy smell ) since then my hair is dry and brittle, no shine, has kinks in it and is always full of tangles when washed. It feels coated and gunky! I cant get my fingers through it and is really really frizzy. ( Far more than it was pre treatment) i understand the stylist used the strongest of 3 strengths of the kerastraight, my hair is coloured ( not bleached) short and fine. it is now breaking and looks dreadful! What on earth went wrong? X

      The shampoo doesn’t contain sulfates which is a plus for people with sensitive scalps. They both have some nice oils. They contain hydrolyzed keratin which will help to moisturize you hair , but won’t do much to repair your hair.. The shampoo has received mixed reviews see:

      Neither of these products contains any ingredient that could be expected to straighten your hair.

      However if you are looking for something to add volume and strength to you hair you will need to use something a bit more powerful. Products that contain the mix of Keratin, Oxidized Keratin and Hydrolyzed keratin will give you much more than simply a hydrating effect. This mix of Functional Keratin®is included in the products:
      • BHAVE rescue shampoo and conditioner
      • Awapuhi Wild Ginger
      • Kuene Keratin Careline
      • Keraplast Intensive Treatment shampoo and condtioner
      And where you see the Replicine™ Functional Keratin® logos you can be sure that these actives are included at the levels that validate the claims of improved fiber strength

    3- apply conditioner to stop the damage is that like CHI kriatin mist ? or what do you recommend ?
    P.S i am a man so i can`t go to a professional salon i have to buy hair product and use them and i need professional help like you guys .
    thank you .

    • Keratin Questions on

      Hi Haitham,
      I’m sorry but I really can’t advise you without seeing your hair. I’m surprised that you can’t go to a salon- surely there is one available to you that will advise men on their hair? As a general rule: any hair straightening treatment will do some damage to your hair so you are best to use the gentlest one that will work for you. The Alkali based relaxation systems are the most aggressive treatments and can cause permanent damage to your scalp if misused. A link for some advice on using relaxers that you may find helpful is:

      There are some relaxers that include Calcium hydroxide rather than lye (Sodium hydroxide) and this is a slightly gentler form of alkali. One example is the Dark and Lovely range.

      The Chi Keratin Mist contains the ingredients: Water , PEG-12 Dimethicone , Quaternium-80 , Polysorbate 20 , Cetrimonium Chloride , Hydrolyzed Keratin , Panthenol , Phenoxyethanol , Caprylyl Glycol , Hexylene Glycol , Potassium Sorbate , Hydrolyzed Silk , Citric Acid , Symphytum Officinale Leaf Extract , Anthemis Nobilis Flower Extract , Mentha Piperita (Peppermint) , Lavandula Angustifolia (Lavender) , Salvia Sclarea (Clary) , Parfum (Fragrance) , Citronellol , Coumarin , Geraniol , Hexyl Cinnamal , Linalool , Silica , Alumina , Titanium Dioxide , Yellow 5 (CI 19140) , Red 40 (CI 16035) 2011

      So it has some hydrolyzed keratin, some hydrolyzed silk in it and oils chamomile, peppermint, lavender, clary sage, and comfrey all of which can be quite beneficial. However more potent hair restorer ingredients include “oxidized keratin” and “keratin”. A range that I would recommend that I think is available in your country is the Paul Mitchell Awapuhi Wild Ginger and especially the Keratriplex treatment if you are having problems.

    Keratin with formaldehyde VS keratin with no formaldehyde; whats the difference? Can keratin without formaldehyde make my hair stay straight for awhile? I m NZ European with a long wavy hair but very damaged (dry, frizzy and not tamed)
    Does it matter which brand (keratin treatment) to straighten my hair? Or the expensive the better the result will be?

    Pls reply ASAP! 🙂

    • Keratin Questions on

      Hi Nikki,
      It’s the formaldehyde that makes your hair straight by adding additional permanent crosslinks across the protein chains in your hair. Keratin on its own will not straighten your hair- but it does help to reduce the damage caused when you use irons. At present a Hair Rescue Treatment with Replicine™ Functional Keratin®is being trialed by Mike Hamel at Ginger Meggs which has locations in Christchurch Auckland and Queenstown. This treatment if used after a straightening treatment will do much to offset the damage that can occur to your hair.

      It last 3-5 months and will help with the frizzies. Here’s a great video which talks about the product and the application process:

    The Keraplast Hair Rescue Treatment with Replicine Funtional Keratin System looks like what my daughter and myself are looking for. We have frizzy curly hair but just want to take the frizz out and have smooth curls. One question is does this system have formaldehyde in it? Also where can we purchase this product as we live in Vancouver, Canada. My daughter is a part time hair stylist so we can purchase right from the distributor if there is one here in Vancouver.

    • Keratin Questions on

      Hi Priyanka,

      There are two sorts of Keratin treatments that you could do:
      One is a keratin straightening or smoothing treatment which will straighten your hair and flatten it. A very gentle version of this is the BHAVE Keratin smoothing therapy. For a video of this see:

      The other treatment that you could consider is a Replicine™ Functional Keratin® Hair Rescue Treatment. This treatment doesn’t straighten hair but will help to restore and repair dry, chemically damaged hair back to a healthy, shiny state. There are two brands that are selling this type of in-salon treatment. They are Keraplast and BHAVE. Both companies also carry a shampoo and conditioner that contain the same type of keratin, Replicine Functional Keratin, which can be added to your hair care routine to ensure the health of your hair.
      You can find out where to get the treatments and products by going to the following links:

    I m from India.I have wavy ,frizzy thin hair. I would like to go for Keratin treatment to make my hair straight …I have never underwent any straightening treatments so far..As my hair is getting damaged day by day, I am planning to get it straightened with Keratin Treatment. Could you please advice me if this treatment is safe on my hair and does it cause more hair loss after the treatment. How long does the straightening effect stays on my hair?


    • Keratin Questions on

      Hi Sravya,
      Regarding straightening treatments, formaldehyde is often used as the straightening agent. There is much more awareness of the risks of formaldehyde and the amounts allowed in straightening treatments have been reduced considerably. A keratin straightening treatment may do more damage to your hair if you are not careful in your selection of treatments.
      These treatments typically last a few months.

      An alternative to the straightening treatment can be a smoothing treatment which is less damaging to the hair.
      One very gentle version of this is the BHAVE Keratin smoothing therapy.

    My hair is very curly and I use a leave in product with keritan in it. I am concerned that it is making my hair less curly. Is that possible?

    • Keratin Questions on

      Hi Arianna,
      I haven’t heard of a leave-in with Keratin that would make your hair less curly. I have wavy hair myself and I use a Keratin based leave-in to keep it wavy. You might want to check that the product you are using isn’t a smoothing product as that will have other chemicals in it that will reduce your curls.

  54. Amie on


    I got a Keratin treatment done at my salon. It was the one in which the salon sprays your hair and then uses a straightening iron to lock in the product. I was able to wash my hair after 24 hours. My hair is extremely straight now when I get out of the shower and I feel I lost a large portion of my volume. While I like the time the process took off from getting ready in the morning, I am concerned I will never get my natural hair back…I didn’t necessarily mind the curls. As far as I am aware, the process lasts 3-5 months (doesn’t grow out, but washes out), but I have read that people said their hair never really went back to it’s natural state after the product fades out. Have you heard of this?
    Thank you

    • Keratin Questions on

      Hi Amie,
      The typical keratin straightening treatment lasts anywhere from 2 to 5 months. Several factors can reduce the length of the keratin treatment: hair type, how often you wash your hair and with what type of shampoo (those with sulfates will strip it faster), the quality of the water you are washing it in (hard water will strip it faster), and if any other chemical process is applied to you hair such as coloring.
      The condition of your hair after the treatment washes out is hard to answer. Only time will tell but your natural texture should gradually return. Keratin treatments like the Brazilian Blowout or Keratin Complex hair Therapy smooth the surface of the hair but don’t permanently break the bond of the hair so your soft curls should return.

  55. keratin is a natural protein that makes up most of your hair. And after read your post i think keratin makes your hair straight.

    • Keratin Questions on

      Hi Angel,
      Yes, Keratin is a natural protein that makes up most of your hair. The properties of keratin are amazing in that they can refresh dryness and damage, but if your hair is naturally curly, there is nothing keratin proteins can do to make it straight.

      Hi Raman,
      The best person to talk to is your stylist. He/she will know the condition of your hair and let you know if it is safe to do the keratin straightening treatment so soon after hightlighting your hair.
      Be careful in choosing your straightener. Try to find one that contains the least formaldehyde (straightening agent). Many brands contain less than 1% of formaldehyde such as Tahe, Simply Smooth, and R&L and are safer to use.

    Hi, I’m a 20 year old male and I’ve been looking at getting a keratin treatment. I’m african american and caucasion and have a mix of both hair types. I have tight, soft curls and it’s pretty frizzy on the sides and towards the back of my hair. I use to straighten my hair with a flat iron about 5 years ago and I’m not too sure if this may be the problem for my extremely unmanagable. My hair is pretty medium-lengthed and was wondering if the keratin treatment would be of any use, or if I should just keep buzzing my hair? Will it make it more managable or pliable?

    • Keratin Questions on

      Hi Walter,
      The Hair Rescue treatment is not a straightening/smoothing treatment. It is an intensive repair treatment that helps to restore dry, frizzy, chemically damaged hair back to a healthy, shiny state.

    • Keratin Questions on

      Hi Pooja,
      Keratin does not straighten hair. It is a fibrous protein that is found in your skin, hair, and nails. It is a beneficial ingredient added to hair care products. Keratin added to hair care products will help in your hair’s health and strength but does not thicken hair.

    I had the Redken Shape Up Straightening done twice. First time lasted me about 10 month which I loved, 2nd time not as long, 7-8 mos. Contemplating having it done again but this time she mentioned this system. Is there much difference and do you have to blow dry to achieve the straight hair? I loved the convenience of air drying along. Would I be able to do that with this? How often can you have it done safely?

    • Keratin Questions on

      Hi Donna,
      The Hair Rescue treatment is not a straightening system. It is an intensive repair treatment that helps to restore dry, frizzy, chemically damaged hair back to a healthy, shiny state. In order to achieve straight hair after the Hair Rescue treatment is applied, a flat iron must be used.

  61. SJP on

    I do not want to go through the keratin treatment process but I would like to know what products I can use that have true keratin in them that may help control the frizz.

    Do all conditioning or styling products that have keratin in them also have formaldehyde?

    My hair is long and I haven’t worn it wavy or in its natural state for about 18 years now because of the frizz so I have been using a flat iron on it daily. I would like to repair my hair and keep it healthier to avoid breakage.

    • Keratin Questions on

      Hi Shila,
      No, not all conditioning and styling products with keratin have formaldehyde in them. The formaldehyde is used in products as a straightening agent. There are many products that contain keratin that help to restore,strengthen, and defrizz hair.
      Replicine Functional Keratin is a great additive to any hair care product. It is comprised of oxidized keratin, intact keratin proteins, and keratin peptides. It is the closest in form to our own natural keratin. Three brands that include this type of keratin in their products are:
      Paul Mithchell’s Awapuhi Wild Ginger
      BHAVE Rescue Shampoo and Conditioner
      Keraplast Intensive Shampoo, Intensive Conditioner, and Hair

  62. Paula on

    Can the keratin brazilian be use on fine hair. Will it make the hair too straight? Thanks

    • Keratin Questions on

      Hi Paula,
      The Brazilian Blowout can be used on any type of hair (fine, course, frizzy, curly) and will typically last for 10-12 weeks.
      The goal of this treatment is to be left with totally frizz-free, shiny, more manageability with less effort. If your hair is fine and wavy, the treatment will make your hair appear naturally straight. If your hair is very curly it helps to eliminate the frizz and enhance the natural wave. If you have straight, frizzy hair it helps eliminate the frizz and enhance the shine.

  65. Bethanie on

    Hi there,

    i am eighteen years old and now have very curly ginger hair. However i didn’t always have hair like this, it used to platinum blonde hair that was completely straight until the age of 14. Looking back,i remember having a keratin treatment at the salon when I had my hair cut, at the time it was dyed brown but then grew out ginger and very very curly-like perm curly! My mother is a hairdresser and has no clue as to what could have changed mu hair so drastically- could it have been the keratin treatment?

    • Keratin Questions on

      Hi Bethanie,
      The present description of you hair sounds great. When using a keratin straightening treatment, with formaldehyde, it combines high heat, formaldehyde, and keratin to break disulfide bonds within the hair which alters its shape. These treatments typically last 4-6 months. To have lasting effects that you describe sounds like something more internal happened from within.

  66. Gurjit on

    My hairs were wavy but I did permanent straighting. After 5 months I don’t like curly hairs .my hairs are very rough ,thin and delicate. I wannna know Keratin hair treatment is good for me because now I like straight hair.

    • Keratin Questions on

      Hi Gurjit,
      There are many keratin treatments on the market. Make sure to read the ingredients. Those with formaldehyde or like chemicals are very harsh on the hair. Derivative names for formaldehyde are quaternium-15, formalin, methanol, methyl aldehyde, imidazolidinyl urea diazolidinyl, morbicid acid and oxymethylene, among others. Be careful when choosing your straightening product.
      Keratin treatments that are formaldehyde free are more intense thermal activated conditioning treatments. This keratin formula works with a blow dryer and 450 degree flat iron to temporarily alter the hair’s shape.

  67. Dianne on

    Hi I have curly hair I’m looking at getting a keratin straightening done I want something that will drop my curls and take majority of my frizz out.

    • Keratin Questions on

      Hi Dianne,
      Keratin hair-straightening treatments are a popular option at salons. The process takes about 90 minutes or so depending on the length of your hair. Most salons offer the following: Keratin Complex Smoothing Therapy, Global Keratin Complex, and the Brazilian treatments. Make sure you ask a salon professional if the products contains formaldehyde-related ingredients or any other ingredients you may wish to avoid. Keratin treatments won’t make your hair break but the flat-ironing after the treatment could so be careful.

    I am a Caucasian, 54 years old woman whose hair texture has now become coarse, frizzy and difficult to manage. I color my hair every 4 weeks and usually wash my hair with shampoo once a week and use conditioner every day.

    I am planning on getting a keratin, smoothing treatment which hopefully will alleviate this problem. Could you recommend a brand which you know has successfully worked to treat the issues I have with my hair?

    I am looking for a formaldehyde-free keratin treatment. My hairdresser wants to use Rusk Keratin Smoothing System. Are you familiar with this system and its successful rate on hair such as mine? I am open to other brands if you think that they might be a better option.. Thank you very much for your reply.

      The Rusk Keratin Smoothing system is formaledehyde and thio free. It states it is formulated to safely smooth texture, reduce cure and eliminate frizz.The results should last up to 14 weeks.

  69. Emani on

    So I am West Indian (Bajan to be exact) and so I have kinky tight curls. However, since I’ve gotten my hair straightened so many times some parts of my hair are straight while the rest is just curly. While that’s not really my main concern since I know how it happened, my real question is; after the process of getting the keratin treatment in and not wetting my hair for 3-4 days, what will specifically happen when I do wet/wash my hair? Will my hair stay straight even when it’s wet or will I have looser curls, or what? Thank you 🙂

    • Keratin Questions on

      Hi Emani,
      If you had a keratin straightening treatment with the guidelines of no washing or wetting for 72 hours you hair should stay straight with little or no wave when washing it for the first time post-treatment. The texture and condition of the your hair should stay the same for 2 to 3 months depending on the how frequent you wash it and if no other chemical processes are applied to your hair such as color, highlighting, etc. These can lessen the straightening time frame. Always be sure to follow the guidelines of the specific keratin treatment you had applied to ensure the maximum results.

  70. Johanne on

    I am in my sixties and have long gray, curly and coarse hair. My hairdresser uses KeraGreen smoothing system on me. She just did it today after I had not done it for almost two years. The problem is that everything was fine until she had to use the flat iron on my hair after blow drying it. My hair turned yellowish, especially in the areas that are the lightest gray. Is there anything that can be done to prevent this from happening. I am planning to wait five days and then I will shampoo with a natural product that provides silver highlights. Will that work.? My hair is becoming much more coarse and curly as I age and the longer my hair gets. If this doesn’t work, I am going to get my hair cut short. Are there any smoothing systems designed for gray, coarse hair?

  71. supreetha on

    my hair smothend permanently can i make it curl for 1 day

    • Keratin Questions on

      Hi Supreetha,
      If you chemically straightened you hair the chemicals used in the relaxer has caused a permanent restructure of the hair strands. You can use a small barrel curling iron or use hot rollers in your hair for temporary curls. Your hair will revert back to being straight when it is shampooed again. Be careful when using heat on chemically processed hair. Extreme heat or extended heat can cause hair breakage.

  72. Samantha on

    Hi! I am very impressed with your I depth responses to all the questions. I had a Keratin Smoothing treatment done to my thick, coarse mid-length hair a week ago. I was very impressed with the noticeable silky smoothness of my hair when it had only been towel-dried. After ironing with a Silver Bullet straightening iron my hair looked amazing – straight, smooth & sleek. The stylist told me she would leave the Keratin formula on for 30 minutes, but she rinsed it off after 20 minutes. I didn’t think much about it until, four days later I washed and conditioned my hair with the sulphate-free products she sold me and I noticed that, while my hair was still a lot softer than before, after drying the frizz and spirals in the under layers had returned. I ironed my hair, and while it is straighter, it’s not at all like it was post treatment. Could my unsatisfactory result be due to the reduction in time the Keratin was applied for? The stylist used Theorie products. Thanks for reading, Sam

    • Keratin Questions on

      Hi Samantha,
      The recommended time for the treatment to be left in the hair is between 20-30 minutes. Smoothing treatments aim to straighten curls, waves and help reduce frizz. Curl reduction after a treatment depends on the original hair texture. With medium-coarse hair there should be a 70-80 in curl reduction.

  73. Liz on

    Can I color my hair the day beofre I get a keratin treatment? I have curly frizzy hair and am looking to have loose waves and be frizz free.

    • Keratin Questions on

      Hi Liz,
      Yes it is safe to color the hair prior to a keratin treatment. If it is to be colored post treatment you need to wait about two weeks.

  74. Diana on

    I have wavy hair and I’m thinking about doing the Keratin hair treatment for the frizz. I don’t always wear my hair straight. Will I still be able to wear it wavy after the treatment?

    • Keratin Questions on

      If you are doing a Keratin Smoothing Treatment it will allow you to eliminate up to 95% of your frizz and curl but it will not straighten your hair. With this sort of treatment you can still curl or scrunch your hair but without the frizz. The hair will retain body & bounce.

  75. Dawn on

    Hi, I have been getting the TR straightening done(I think it is Japanese straighteneing) I have very thick spiral curls naturally. I would like to let my hair grow out, but it is somewhat of a nightmare with curly roots, I am blow drying forever. Is there any product that would help in the growing out process so I wont be blow drying straight for over an hour?

    • Keratin Questions on

      The TR (Thermal Reconditioning) Straightening has a chemical that breaks the bonds that give each hair strand its shape. This treatment changes the structure of your hair permanently until new growth occurs. Unfortunately the grow out period is difficult to endure and many give up and straighten the new growth. Unless you do a smoothing treatment on the new growth to help relax it tp make it more manageable, you will have to blow dry and straighten the new growth. Make sure to check with your stylist before doing any other treatments. He/she may have some good advice to help you get through this period.

  76. Porothy on

    I got a Coppola keratin treatment done about a month ago, and I was hoping for stick straight hair, but I am not happy with it. The day I washed it came back with curls and frizz. I don’t do any research before I got this done, my friend recommended it. My question is really when can I go to a different salon and get a straitening treatment to make my hair stick strait, do I have to wait for this to grow out? Thanks!

    • Keratin Questions on

      Hi Porothy,
      If you used the Keratin Complex by Coppola it is not a straightening treatment but a smoothing treatment so your hair will still have wave or curl. This type of treatment should reduce the frizz and slightly relax the curls in your hair.
      To straighten the hair a flat iron must be used. Reading the Coppola directions treatments can be done every 4-6 weeks so you should be able to do another type of treatment by then but check with the professional stylist that you plan on using for guidance on the best straightening options for your hair type.

    Saw the quick responses, hoping that I can actually get one too.

    My name is Tim, I’m 20 years old, and I have naturally curly, wire-like hair.

    I chemically straightened my hair previously, which did nothing but make it a little easier to straighten.

    Tomorrow I will be getting my hair straightened with the keratin treatment, and I’m wondering a few things.

    1. Will I really not be able to wash my hair for a few days after the fact?
    2. Will my hair be naturally straight when washing, or will I NEED to blow dry it or even straighten it.

    I’ve rarely ever dyed my hair or had chemicals put in it besides shampoo or conditioner, so I think my hair will do well with it. I’m just worried that it might not really make a huge difference in the end.

    • Keratin Questions on

      Hi Timothy,
      After most keratin straightening treatments it is advised not to wash the hair for at least 2 days and with some they suggest wait at least 3 days to wash the hair. It is advised not to get any type of moisture in the hair prior to the first shampoo which also means avoid exposure to sun or exercising which will cause the scalp to sweat. The treatment should eliminate about 95% of the frizz and curl from the hair. It should also help to reduce your drying and styling time.

  79. Tm on

    I have naturally curly hair… I love! I don’t want any chemicals, relaxers or straightening products or treatment. I wanted to try Shea moisture noni & monoi conditioning shampoo with peptide and keratin as well as the rinse out conditioner. Are these natural products or are they considered chemicals ? I emailed the company for additional information but have not heard back. I know little about keratin and I am not keen on different products as I like to stick to one thing but thought I’d give it a try.Thanks for the insight.

    • Keratin Questions on

      Hi Tim,
      Keratin is a natural protein found in your hair, skin, and nails. As we mature keratin loss can lead to a dull finish, cause frizziness, or loss of sheen. By restoring and replenishing lost keratin the the hair, it will become more manageable and shinier. In shampoos and conditioners look for products that contain oxidized keratin which helps repair the hair and hydrolyzed keratin helps to put moisture back into the hair.

  80. Lyn on

    I had a straightening process just over a week ago. I though it would get rid of the grizzlies but most of the body and curl would be kept. I instead have stick straight hair and look ridiculous. What is the best method for reversing? I have read using sulphate containing shampoos and good old table/sea salt. What about a permanent color?

    • Keratin Questions on

      Hi Lyn,
      Professional stylists recommend using shampoos containing sodium chloride and washing frequently to help straightening treatments wear off. Exposure to chlorine, salt water (can be in the form of a water bottle spray with sea salt), the sun, and frequent washing will help shorten the lifespan of the treatment.
      The salt may dry out the hair so condition it well.

  82. Anthony on

    When hair is altered from curly to straight by applying heat with a pair of flat heating tongs, what is happening to the structure of Keratin? Is this process reversible? When hair is altered from curly to straight by the addition of a chemical relaxer, what is happening to the structure of Keratin? Is this process reversible?

    • Keratin Questions on

      Hi Anthony,
      The hair is comprised of up to 95% keratin. Our natural keratin can be depleted when the hair is damaged chemically, physically, or from the environment. It can be damaged from the overuse of thermal styling tools such as curling or flat irons.
      There are products on the market to help repair and reverse hair damage. Two products that contain Replicine Functional Keratin, which is comprised of oxidized keratin, intact keratin proteins, and keratin peptides, are Keratriplex and Hair Rescue.
      Keratriplex is from Paul Mitchell
      Hair Rescue is from Keraplast Technologies
      These products will help repair and restore dry, frizzy, chemically damaged hair back to a healthy, shiny state.

      When hair has been chemically relaxed the chemical bonds of the hair are broken, altered, and then reformed into a straight, relaxed pattern. Once a relaxer is applied it destroys the cuticle’s layer which gives the hair its texture.The cuticles, responsible for holding curl, are dissolved and the protein structure of the hair is altered. Hair care professionals say the process cannot be reversed.
      Professionals suggest to wait it out, use products to help maintain your hair’s health, and to cut the hair regularly.

  83. Tracey Green on

    I had my hair keratin straightened this week, with Bhave.
    My hair is very curly naturally. I washed my hair yesterday after 48hrs, with the appropriate shampoo and condioner and chose to let my hair dry naturally. The outcome was a much softer and relaxed curl with straight ends. Blow waving is much much easier and half the time to style. Has this worked or should I expect my hair to be completely straight when it dries naturally .

    • Keratin Questions on

      Hi Tracey,
      It sounds like you received great results from the bhave straightening treatment. Straightening treatments will not straighten your hair completely but will reduce between 50-80 percent of the curl depending on your original hair texture. When it is naturally dried it should still have a slight wave to it.

  84. Kim on

    I live in Florida, have frizzy, wavy hair and I don’t have time to flat iron it. If I get my hair chemically straightened will I be able to let it air dry and have it stay straight? I’m tired of pony tails.

    • Keratin Questions on

      Hi Kim,
      Straightening treatments claim to shorten your blow-dry time by 40%-60%.They claim to eliminate frizz and straighten curls and waves for about three months. They do not guarantee completely straight hair but it can reduce between 50-80 percent of the curl.They say you can walk out in moist or light rain and your hair won’t change.

    I have a question I recently did the straightening treatment n after the 3 days I washed my hair n its curly again it is soft but I honestly thought I would have straight hair that’s what I thought that was the point of it so did the hairstyles do it wrong or am I wrong?

    • Keratin Questions on

      Hi Sarai,
      Keratin straightening treatments will give you smoother, straighter strands but you may still need to flat iron the hair to get the look you are trying to achieve. These straighteners claim to reduce volume, frizz, and your drying time but do not give pin straight hair.

  86. Kami on

    I wanted to ask for help. I have curly hair and I´ve been going to my hair dresser for 2 years now. Each 6 months I have had my hair chemically relaxed with Keratin and now sadly 50% of my hair has broken off leaving me with hair about 5cm long from about 60cm. It has alot of gaps in it now and I cannot do anything with it. I wear a cap or gel it all back most days. I am totally frustrated & sad by this and at times feel like shaving it all off. Is there anything I can use to stimulate hair growth and get it back to being healthy again? I would love my hair back.

        I am interested in getting the keraplast system. I recently did a Japanese thermal system and then a keratin sytem just because my hair had a little frizz at the ends. I used the ION keratin system it says it is formaldehyde free and has vannillin, is vannillin a form of formaldehyde? and is it ok to use the keritin treatment after the Japanese straightening treatment?

        • Keratin Questions on

          Hi Traci,
          Vanillin is the chemical compound found within the pods of the vanilla plant. This compound is what gives vanilla taste and fragrance. The demand for vanilla extract exceeds its production and alternatives for the flavoring/fragrances were needed, hence synthetic vanillin. The production of synthetic vanillin is derived mainly from wood pulp and is cheaper to make than naturally extracted vanillin. Ethyl and methyl vanillin are synthetic substitutes for naturally extracted vanillin but are not a form of formaldehyde.
          Salon professionals say it is safe to do keratin treatments over Japanese straightening treatments but to wait at least two weeks.

    I’m 18 years old and I’m thinking to get my hair straight by the Keratin (straightening) treatment.
    My hair are dry, weak and curly as well.
    I cant leave my hair open in public because I feel so embarrased
    I really want to get them straightened somehow for months and not for just a few days
    Help please?

    Hello Ma’am /Sir, I read the information you have shared. I totally understood about the treatment thank you for that. My question is I had done straightening and I am regretting because they look artificial. I am now interested to take keratin treatment but as I have minimal wavy hair would it affect and straighten my hair?? I just want my hair to be smooth and manageble but dont want straight hair because my original hair are better because they are thick and even wavy not curly. So please do tell me about it.

    Hi Team,
    I have natural wavy hair but i have gone for a rebonding in the past and then for smoothening and now my hair are weak and frizzy and i am facing a lot of hair fall ,would keratin be a blessing for my hair if i go for it it or would it worsen the hair quality also please tell me if keratin decreases hair fall or increases.

    • Keratin Questions on

      Hi Priya,
      The use of keratin will not decrease your hair loss or damage your hair. Overuse of heat and extreme heat after straightening and smoothing treatments can cause damage to the hair.
      You may want to consider a keratin repair treatment. Paul Mitchell’s Keratriplex and Keraplast’s Hair Rescue are two companies that carry a product which includes Replicine Functional Keratin. This type of keratin is the closest in form to our own natural keratin. It is comprised of oxidized keratin, intact keratin proteins, and keratin peptides.
      These treatments help to restore dry, frizzy, chemically damaged hair back to a healthy, shiny state.

    I’m raphael
    I used to have short hair all my life but last year I tried to let them grow a little
    My hair is natural straight, but so dry and damaged that seem frizzy and curly
    I tried the “simple” way of straightening without keratin few months before with great success and my hair became thin and straight as I wanted them. But the results lasted for 2 months and a month later I went to make the process again but the hair dresser told me to try the “keratin system”. Anyway, my hair become straight again, but after the 3rd day that he told me to wash my hair after the treatment nothing was the same, few days later my hair become frizzy again with obvious damage.
    I stayed that way for 3 months and I visited a hair dresser today to make the classic straightening without kerratin. He told me that with the regular way all the hair that were applied with keratin before will be destroyed and I will have to cut them and stay with short hair, and that with the Brazilian straightening my hair will become really straight again, just a little more dry.
    Is that possible? What should I do?

    • Keratin Questions on

      Hi Raphael,
      Breakage, dryness, and hair loss can be side effects from straightening treatments. These are caused by the chemicals, such as formaldehyde, and the intense heat used with flat irons. Keratin is placed in the formulation to help offset the damage that can be done to your hair by chemicals combined with heat. The keratin will help strengthen, hydrate, and add shine to the hair. It is always best to speak with a trusted professional when choosing a straightening treatment. They will be able to help you in choosing the best treatment for your hair type and one that will provide the desired results you are seeking.

  95. Rashida on

    I am african American and have had relaxed hair for many years. I recently got a keratin straightening treatment and really like it. My question is what happens as my new growth comes in. How does the new growth get straight if you don’t get it done for another 4-6 months? Does the shampoo/ conditioner do that or does it just grow out and you just have new growth until the straightener gets applied again 4-6 months later? I’m concerned that once it starts growing out, it will really look a mess. Thanks for your help!

    • Keratin Questions on

      Hi Rashida,
      Keratin treatments claim to straighten hair naturally by filling in the cuticle and coating the hair with protein. Keratin treatments do not break the bonds of the hair as opposed to relaxers and permanent straightening treatments. Because the bonds or structure of the hair aren’t broken down, the hair tends to look normal and natural with regrowth. A keratin treatment will wear off and will require reapplication in about three months. Using a sulfate/sodium free shampoo and condition can help to lengthen the life of the straightening treatment but won’t help make regrowth straight.

    Thank you for all the helpful info. However I still have a question: What happens if I add hydrolysed keratin to a shampoo already having keratin in it?

    • Keratin Questions on

      Hi Telly,
      Shampoos can contain a blend of keratins such as oxidized keratin and hydrolysed keratin. Many keratin derivatives are named in hair care product labels such as hydrolysed keratin. Keratin derivatives bring different benefits and hydrolysed keratin acts as a conditioning agent. This type of keratin is limited and has been modified from its original source material.

  98. Magi on

    do keratin smoothing systems NEED a protein sh/cond for home maintenance? Because the bonds are reformed with keratin/protein do aftercare products contain a higher level of protein to prolong the life of the service?

    • Keratin Questions on

      Hi Magi,
      Post treatment shampoos/conditioners should be sulfate, sodium free. Using this type of product will help the longevity of the smoothing treatment. Sulfates are used in shampoos as sudsing agents and can strip the hair. Sodium is used as a thickener but will dissolve keratin and leave the hair feeling dry. It has been suggested to shampoo with cool or tepid water and follow with a cool rinse to give straightening/smoothing systems long lasting results.

  99. Lea on

    I got a karatin treatment that does contain formaldehyde without knowing It contained that harmful chemical.. I heard that the chemical is released wen you add heat. And that is when your breathe it in and it’s bad..
    So I have showered twice since I got it done.. If I straighten my hair will the chemical still be relesed in the steam?

    • Keratin Questions on

      Hi Lea,
      Studies have shown that with a formaldehyde based keratin treatment, hair continuously releases formaldehyde as it slowly reverts to its natural curly, wavy, or frizzy state.
      Measuring how much formaldehyde vapor is released from straightened hair over time has not be tested. Make sure the room is well ventilated when styling your hair in case any vapors are released.

I color my own hair-wash, apply mousse and go..I would like to have that same easy and fast routine after any treatment. Can you tell me what are my options..don’t want straight hair! Carol

    • Keratin Questions on

      Hi Carol,
      Hair needs moisture to help keep it smooth, manageable, and soft. Hair products containing sulfates, sodium, detergents, or chemical agents can strip away moisture, leaving it dry and frizzy. Fatty alcohols (cetearyl, cetyl, and stearyl) can help to condition. Also products with low pH and little fragrance are suggested. Be sure to check your labels before buying to ensure the products will help to condition instead of adding dryness and frizz to your hair.

    I am African with type 4c hair. I recently did a keratin treatment using Keune in my country. I love the outcome. However, I live in Madrid, Spain and I have not seen any salon that uses Keune here or even the after care products being sold here. I cannot order a smoothing pack because it is only sold to salons.

    I was wondering, is it possible to retouch using a different Keratin treatment? Will it conflict with the Keune treatment? If anyone lives in Madrid, do they know of any salon that uses Keune?

      There should be no problem using a different keratin treatment to do touch ups but check with a professional stylist to see which one is recommended for your hair type.

    Hello, thank you for sharing these informations, I’d like to ask you a few questions about the “Keratin straitening treatment” , I have a curly but frizzy hair, and I would like to get rid of the frizz without having my hair “dead straight” I have been using products with sulfate and they damaged my hair a whole lot, I’m jst sick of having a frizzy hair that looks like crap, so I’m kind of confused whether to go for the kerating straightening treatment or use conditioners or whatever as long as I keep the curls but in a shiny way, please answer me asap thank you.

    • Keratin Questions on

      Hi Zineb,
      Before doing a keratin treatment which can be costly, you can try using sulfate, sodium free shampoos and conditioners. These products tend to dry out the hair and can cause “the frizzies”. One brand is the Paul Mitchell Awauphi Wild Ginger line. These products will help repair and rebuild dry, brittle hair. The line also includes Keratriplex which is a repair treatment that helps to strengthen hair and protect it from further damage. The Awauphi products will let you keep your curls but help to eliminate frizz and strengthen hair at the same time.

    I had the keratin treatment a few years back, my hair was really wavy before and then become straight and since then I’ve not been able to get my full waves back, it’s just become a little frizzy. Will my full waves ever return and is there something I can do to get them back?

    • Keratin Questions on

      Hi Isabella,
      There are many types and brands of keratin treatments on the market. Results vary depending on the texture, length, and thickness of hair. Keratin treatments advise to stay away from shampoos and conditioners that contain sulfates and sodium because they can lessen the length of a keratin treatment and tend to strip away the keratin treatment. This may be an option.

    * Hair Power Dose
    * Brazilian Blowout

    Because I don’t know what treatment should I get. I’m Asian (with black, fine & sort-of-straight hair). There are days that my hair is so limp and lifeless. While there are some days that it is wavy at the bottom and very unruly.
    I tried to blowdry it or iron it, but seems to grow very weak and prone to breakage, split ends and even hair fall.
    Please help!!! I want my hair to be rescued; and be fabulous.

      Hi Zhazha,
      It is always best to speak directly with a hair care professional when choosing a treatment. They will be able to advise which is best for your hair type and will provide you with the desired results you are seeking.
      Keratin treatments, the Brazilian Blowout being one of them: take about 90 minutes; will shorten the blow-dry and straightening time by 40%-60%; eliminate frizz; will have a 3-4 day waiting period; recommend the use sodium-sulfate free shampoos; lasts about 2-3 months.
      Powerdose treatments by L’Oreal: This treatment helps revive dull, lackluster hair. It is described as a powerful, rinse-out repair treatment that helps to restore and prolong hair color. These lasts up to 8 weeks. It is for every hair type- fine to course.

    Hi! I just got this treatment done and i’m wondering if using a keratin based shampoo could help to make it last and not wind up ruining it, or what would you recommend for this purpose?

    • Keratin Questions on

      Using a keratin based shampoo and conditioner after a keratin treatment is recommended. Only shampoos and conditioners that are sulfate, sodium free should be used. Products containing sulfates and sodium tend to dry out and strip the hair.

  107. Jenn on

    My stylist tells me there is a keratin treatment that will relax and smooth my fine, very curly hair (I have fairly loose curls) – not completely straighten it, but get rid of the frizz for about 2 weeks and make it “wavy” rather than curly. I am leary to try this because nothing has ever been able to do that for my hair and I’ve tried many different products and treatments. I had it chemically straightened twice with the regular “reverse perm” technique and it did not work; both times it was just as curly again the next day as it had been before, even tho the stylist insisted it would stay straight. I also have tried the DIY keratin straightening kits at home and have not been able to achieve more than 1 day of straightening, even though they claim to last for 7-14 days. I also did not care for the texture of my hair with use of these treatments, it felt like “horse hair”. I think it’s because my hair is fine that it’s so difficult to relax/straighten. Do you think I’d have similar results with this keratin treatment my stylist is recommending? I just don’t want to waste my time or money, but it would be awesome to have less curl/frizz when it gets humid in the summer. The only thing that really seems to relax/straighten my hair is a flat iron, but when it gets the slightest bit humid it always curls and frizzes.

    • Keratin Questions on

      Hi Jenn,
      You did not mention the name of the keratin treatment suggested.
      The Paul Mitchell line has Awaphui Wild Ginger Keratriplex which is a keratin treatment that can help with frizzy, damaged hair. It can help strengthen hair while adding elasticity, softness and shine.
      Keratriplex has Replicine Functional Keratin which is the closest in form to our own natural keratin found in the skin, hair, and nails. Many salons offer this treatment.
      Using sulfate, sodium free products will help to ensure the length of a keratin treatment because they do not strip the hair of the keratin treatment or cause dryness.

    quick question, curly frizzy hair. just want to eliminate frizz and relax curl minimally….best product?

  109. Nissaz on


    First, let me say that this is the FIRST website I found throughout my extensive research in the matter that provided as much information, with honest and factual details.
    I commend you on your commitment to helping people on this very controversial topic. It is virtually impossible to find truthful information from the makers of the products, let alone hair professionals, who all want to protect themselves. Thank you!

    Here is my question: I understand that formaldehyde is an “essential” ingredient if you are looking to straighten your hair during a Keratin Straightening treatment.
    I am north african and have curly (medium ringlets) but very frizzy hair, especially around my forehead, in front of my ears and on the top of my head.
    I have had 3 different Keratin Treatments done:
    – Kerastraight: did NOTHING (formaldehyde level is apparently less than 0.02%)
    – KeratineCure: did NOTHING (formaldehyde level is apparently 5%)
    – A product from Brasil, which was applied to my hair by my friend’s stylist who works in a small salon. It worked WONDERS!
    I can only assume the level of formaldehyde is higher than 5%, since the KeratineCure (at 5%) did nothing to my hair in comparison.
    (I have yet to find out what brand of Keratin Straightening treatment was used then.)

    I have to find a similar alternative, which will potentially bring me the same results.

    The one I am looking at is the Cadiveu – Brasil Cacau (Brazilian Thermal Reconstruction)
    Would you be able to find out the actual % of formaldehyde present in this product?
    By the looks of it, it seems to be one of the best out there, with lasting results (similar to the ones experienced with my “obscure” brand from my Brazilian friend).
    It is also one of the brands that allows no “down time” after the treatment: no need to wait 72 hours to wash, pin or wear your hair up.

    Here is their website in the US:

    I’m hoping you can help me with this!

    Best regards

  110. Hair Dilemma!! on

    I have had the Keratin applied three times. The first time was great, the second time it didn’t take so she did it over a week later. I like the idea of not using any chemicals in my hair but as a professional in the business world I can’t go around with my hair looking horrible. The Keratin treatment only lasts about 4 weeks and it is so expensive. As soon as I sweat it goes back to its natural state. So I have decided to go back to a perm but one with less chemical strength.

    My question, and I have been looking everywhere for an answer to it, is : How long do I have to wait after getting a Keratin treatment before I can go back to a perm?

    The perm I am planning on using is Design Essentials Sensitive Scalp relaxer. I believe my stylist uses Ion Keratin treatment but I am not for sure. I really look forward to your answer.

    • Keratin Questions on

      Professionals advise waiting three months after a keratin treatment before any other chemical process is applied.
      It would be best to check with the stylist doing the perm.

      • Hair Dilemma!! on

        I was told by my stylist that the Keratin Treatment was not a chemical process. Is that true? I was hoping that because it wasn’t a chemical process I could begin using a perm right away. If I put a perm on it before three months what will happen? Will my hair fall out?

        • Keratin Questions on

          If the keratin treatment straightened your hair in any way chemicals were used.
          Using chemicals frequently and/or heat from the flat iron can damage the hair, causing it to be brittle and dry, making the hair break easily.
          Doing a perm before the three month period is over doesn’t allow the hair time to heal and strengthen.

  112. Carlita on

    Hi, I have recently got a treatment done. The product used was Inoar Brazillian Keratin Treatment (formalyhyde free) not sure if this is true as my natural extremely thick afro is now pin straight and thats before blow drying. Has the treatment or heat damaged my hair beyond repair? Or once it washes out will my afro return? Im worried because when i first got a Keratin Treatment years ago, my hair turned into a more manageable and softer afro. I was able to then switch between wearing it in an Afro puff or wearing it sleek and straight whenever I decided to apply heat. However this time round a good 7 years gap in between on completely virgin hair its straight before blow drying. Did the salon do it wrong?

    • Keratin Questions on

      As long as the bonds of the hair are not broken, as in a Japanese straightening or thermal reconditioning treatment, hair should return to its original state in two to four month, depending on the after care. Inoar includes 0.2% formaldehyde in its Moroccan Brazilian Keratin Treatment ingredient list. This treatment should smooth the hair surface but not permanently break the bonds of the hair. Hair should be smooth, less frizzy, more manageable if left to dry on its own but not pin straight.

      For daily hair care use after a straightening treatment, it is best to use shampoos and conditioners that are sulfate and sodium free to help prevent dryness, frizzyness, and help to ensure the longevity of the straightening treatment.

    I have gone through keratin treatment for straightening my hair 4days ago. But I couldn’t see the expected results. my hair is still curly to an extent even after the straightening process. Can I go for any other straightening treatments now? Or should I wait for some time?

    • Keratin Questions on

      Hi Druvitha,
      It is best to speak to a hair care professional firsthand. They will be able to see the condition of your hair and help you achieve the results you desire. The continued use of harsh chemicals can damage your hair. Once hair is damaged it can be repaired but it takes time and often repair treatments which can be costly. With severely damaged hair, it often requires cutting. So it is better to play it safe and seek professional advice.

    Hi I’ve gotten a smoothing treatment 3 months ago and I’ve noticed that my curl pattern has changed from a 4b/4c to a 3c/4a. And I’m a little worried my my natural curl pattern will not go back to how it use to before I put the treatment in. The stylist told me that it would take 20 washes for it to come out but so far my natural texture hasn’t returned. Will my natural texture come back?

    • Keratin Questions on

      Hi Jessie,
      Over a period of time your original texture should return. A smoothing treatment doesn’t break the bonds of the hair as in a Japanese straightening or thermal reconditioning treatment.
      Frequent washing does helps reduce the length of a straightening treatment.

      Hi Nicole,
      Keratin is placed in hair care product to strengthen, add shine, and elasticity. Keratin does not straighten hair. Keratin is added to straightening treatments to help protect the hair from any damage that may be caused by the strong chemicals used to achieve the desired results. The chemicals added such as formaldehyde are what change the hair’s structure.

    So I just permed my hair, and my mom bought me a Brazilian Keratin Treatment… Is it safe to use? or it will ruin my curls? thank you!!

      Brazilian Keratin Treatments are used to help smooth or straighten hair depending on the type that is applied.
      Using a Brazilian treatment should affect the curls in some way. Both perming treatments and Brazilian treatments use harsh chemicals to alter the hair.
      Overuse of harsh chemicals can cause the hair dry out and damage it. It is best to speak directly to a hair care professional before you use any other product on your hair.
