Keratin Hair Treatments, Hair Rescue Treatments and Replicine Functional Keratin

Article one: Keratin-just what is Keratin? 

“Keratin” seems to be the latest fad when it comes to hair treatments, and it can be so confusing with all these different treatments that have “Keratin” in their name!

Some of these are meant to be good for your hair and some have received some pretty bad press recently.  In fact so bad that Keratin is now described by some as the “K” word –never to be mentioned in civilized circles!

So what does it all mean?  Over the next few weeks we will be running a few articles to talk about this. In this first article we will talk about Keratin- just what is Keratin?

Samantha, one of our KeratinQuestion bloggers, recently asked an excellent question. She asked:

If the body stopped producing keratin, what would be the effect on the hair?

Well, the short answer to that is that you would not have any hair. But the longer answer is that not much else in your body would function either.

Keratin is the name of a group of fibrous proteins produced by your body. Hair is almost entirely Keratin. The other key component in hair is water, the amount of which changes depending on the state of your hair. Dry hair and damaged hair will contain as little as 10% water, while healthy hair will typically contain about 16% water. The third component of your hair are lipids which make up only 1% and these are a mix of lipids on the surface of your hair and what are called internal lipids within the cellular structure of your hair. All in all, this means that up to 90% of your hair is Keratin. (So it makes sense that, to do any repair work on your hair, you would use a material that is most like your hair!)

But Keratin also forms a key role in other parts of our body. It is an essential structural component of all the soft tissue cells in our body. If we didn’t have Keratin our skin would fall apart, as would all our internal organs. They would lack any structural integrity as keratin is key in providing structural strength to the cell of these organs.

We wouldn’t have any nails as these are also almost entirely Keratin. Even our bones contain keratin within the osteoblasts cells which are the cells that generate the Calcium phosphate structure of our bones.  Simply put Keratin is one of the key essential protein types in our bodies and is absolutely critical to our physical wellbeing.

Keratin is present also in the bodies of other animals, in soft cell structures, and in fur, horn, feathers and wool. Sheep wool has a very similar structure to human hair and is a key source of keratin that is used in the personal care industry. The nice thing about using sheep wool is that sheep have to be regularly shorn of their wool as an important part of animal care and are not at all harmed in the process of shearing.
There are several processes for converting the wool, once shorn,  into  the soluble Keratin that is in hair products.  The type of process used is critical in what properties the resulting keratin product has and what functionality it retains and confers on the hair product it is used in. In the next two articles we will talk about the different types of keratin, their functionalities and two types of treatments that you will know of as keratin treatments for hair.

    Hi, I like your comprehensive site and thorough responses to questions. I have three questions. Firstly, my situation: I’ve been dying the grey out of my hair every 7 weeks now for about 3 years and my hair is flat, super porous, and much thinner. I used to be able to just twist my hair, let it dry, and it would be nice and wavy, thick. Now it’s just boring/flat. Is this more likely due to aging or to more likely the coloring? Secondly, which keratin treatment of the two would you recommend? Thirdly, I’ve looked at the salons in my area that your site says offer the treatment but the salon website doesn’t specifically say it offers the keraplast treatment. Thanks!

      Hi Rachel
      Many thanks for your positive feedback. It’s very encouraging to hear that our efforts are appreciated!

      Regarding your questions:

      Unfortunately our hair does deteriorate as we age (as with the rest of our body! ). You may have found your hair to be fussier in how it responds to different hair products and be less tolerant of the inexpensive supermarket/drugstore shampoos than it used to be. And research has shown that dying also can have a detrimental impact on hair. The extent of damage will depend on the type of dye and whether or not it has bleach incorporated. Also the quality of the conditioner that is included as part of your dye process will have an effect on the quality of your hair.

      Getting older means that if we want to still look good we have to put more effort into taking care of our body. With hair, as with our skin, using quality products can make a huge difference.

      You may like to have a look at the type of shampoo that you are using- maybe it’s just too effective at stripping the oils from your hair? Have a look at the surfactant system that is the basis of your shampoo. Ammonium Lauryl sulfate, Sodium lauryl sulfate and sodium lauryl ether sulfate have been around for a long time and are very efficient at cleaning but they may be too harsh for your hair now. There are a large number of new types of surfactant system now available that are gentler. The Isethionate derivatives are a gentler alternative that provides great foam and there are others such as the sultaines, succinates, cocoamphodiacetate, cocamiodopropylbetaine which are some of newer gentler surfactants now available.

      Also important are the conditioning agents that are included in your hair products. Natural oils such as argan oil, grape seed oil and rosemary help to keep your hair condition, as well as quats such as behentrimonium chloride, Behentrimonium methosulfate, and humectants such as glycerin, and hydrolyzed keratins help to keep moisture in your hair.

      And, of course, keratin and oxidized keratin are great for your hair. Keratin is a film former and will form a protective layer on your hair to guard against the effects of environment sun and wind. The oxidized keratin can actually associate itself with the proteins in your hair to help repair small fractures in the fiber. And Keratins are very good for your skin also- so good for your scalp. Just watch that you don’t get fooled by a product that has Keratin in the name but not any keratin in the formulation. You can tell this by looking carefully at the ingredient list for the words “Keratin”, “Oxidized Keratin” or “Hydrolyzed Keratin”.

      Getting into the habit of applying a good quality leave-in product such as a conditioning cream will also help to maintain the condition of your hair.

      Regarding your second/third questions: I think that you may be referring to the alternative Keratin straightening treatment or Keratin Hair Rescue Treatment which is definitely not a straightening treatment. This would only exacerbate your hairs declining condition.

      However the Keraplast Hair Rescue Treatment with Replicine™ Functional Keratin® would be very beneficial and help to add volume, shine and condition back into your hair. It has been only recently released to some of the salons on the salon locator so it may be that your local salon has not yet updated their marketing information? You might like to give the salon a call – or if you have any issues get in touch with Keraplast at

    My hair is brittle, freeze, over processed, no elasticity, hair loss, dry, dull. I have used different treatments and products, but none of these has worked. I am interested in the Hair Rescue Replicine with functional keratin treatment (BHave). Could you contact me or a hair salon in my area that could provide this service? My address is 4703 Thistle Hill Drive, Aberdeen, MD. Tel: 410 652 2243. Any of these areas in the State of Maryland are accessible to me: Aberdeen, Perry Hall, Fallston, White Marsh, Bel Air, Forest Hill. Do you recommend a BHave hair rescue replicine functional keratin to smooth, relax, calm, and nourish hair, or the natural treatment without any chemicals? Please reply! I am desperate. I need help. My hair is porous and have lost its natural curls. Thanks.

    • Keratin Questions on

      Hi Rackell,

      Keraplast have a salon locator which you can find at:,com_storelocator/Itemid,76/view,map/
      Or if there isn’t a stockist 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.

      As you point out, BHAVE also have a rescue treatment called Hair Rescue that contains Replicine Functional Keratin. I’m not aware that their product is available in the US as yet , but you could contact them on their facebook page and ask them if and where the BHAVE products are sold in the USA. In either range I would strongly recommend the hair rescue treatments. Another option would be the Awapuhi Wild Ginger Keratriplex treatment.

  3. Katie on

    Can Keratin build up gradually over time if you have the treatment done every 3 – 6 months?
    (i.e. will it assist in treating it longterm if you have a quarterly treatment, or does it completely wash out after 6 months)?

  4. Angela on

    I have very thin, fine, damaged hair. I can’t seem to grow it past my chin as it just breaks off. I know that part of the problem is an antidepressant that I’ve been taking for years. It has thinned my hair out and made it weaker. The other part of my problem is that I highlight my hair every 6-8 weeks. Even though I have this done professionally, once my hair reaches my ears it just splits and breaks off. I feel like I’m in a catch 22 though because if I don’t highlight my hair, it’s just not manageable at all! Will Keratin help my hair situation? If so, exactly what treatment and how often? I’m very desperate as I’ve tried just about everything out there sparing no cost as so far nothing has helped. Any suggestions you have would be greatly appreciated.

  5. Smita on

    what are the brands for keratin hair treatment, which one is recommended?

    • Keratin Questions on

      HI Smita,
      I think that you are probably talking about a keratin straightening treatment? There are lot of these and it depends on your hair type and condition as to which one is best for you.
      BHAVE has a good smoothing treatment and it includes the Replicine™ Functional Keratin® to maintain hair health. However this is not available in all countries. You could contact them and ask them about their salon locations at:

    Hi , my hair has been over processed and is so damaged it has snapped off and my hair is a disaster ! I was wondering if I was to out a keratin complex treatment on my hair would it stop it looking so frizzy ? I’m having to wash my hair everyday to try and get it into a style because I’ve had to had it cut into a really short bob 🙁 one side has snapped off to about. 3 inches , my Hair is not greasy so doesn’t need washing every day. It’s making me so depressed the state my hair is in and I’m just wondering what product would be best ? Either a full keratin or a blow out ? Please please help. ! I just want my shiny long hair back !!!

  7. Chloe on

    Ok, so I’ve been thinking about getting the keratin treatment done soon. My hair is not curly at all, just a little wavy. It’s also kind of thin. I know that after the keratin treatment is finished, your hair will be flatter. I’m not getting it to make it perfectly straight (although that would still be nice).. I want to get it if it repairs split ends. Does it? My hair is pretty damaged but I do not want to cut a bunch of inches off. I would like to chop off about two & then get the keratin. Will this repair my damaged hair or should I just go ahead & get my hair cut short?

  8. Rekha on

    I had a keratin treatment done in India with Loreal’s “x-tenso” products.
    following tht, my hair is still very dry and rough and hard to manage, tangled . ( even using their recommended shampoo and conditioner ). can you please recommend me a product?

    • Keratin Questions on

      Hi Rekha,
      There are alternatives that may be better for your hair. 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:

      Keraplast salon location and contact:
      To find a USA salon near you, you could try the Keraplast Salon locator at,com_storelocator/Itemid,76/view,map/

    I had the nanokeratin treatment 6 days ago and followed the instructions and washed my hair with a non sulphate shampoo and conditioner 3 days later. I have naturally very curly hair and with that comes frizz. I thought that this treatment would be perfect for me, losing the frizz and keeping the curl! However, it has loosened my curl dramatically, to the point of only being slightly wavy now. I have washed my hair every day to try and loosen the keratin and wash it out a bit but there is no change as yet. I am going back to the salon to discuss what has happened and may have to have the keratin washed out completely. Is there any reason why this has happened, as everywhere I read it says that nanokeratin will NOT straighten curly hair?
    Kind regards,

    • Keratin Questions on

      Hi Rosa,
      When looking up Nanokeratin treatment it has Formaldehyde as one of the key ingredients. This is used to dissolve the chemical bonds in hair and restructure them. It gives straighteners a lasting effect.
      As an alternative, Keraplast has a keratin treatment called Hair Rescue. The Hair Rescue contains Replcine ™Functional Keratin® which is a combination of oxidized keratins, intact keratin proteins, and keratin peptides. This product contains no harmful ingredients, is safe for all types of hair, and the keratin used is closest in form to your natural keratin. Hair Rescue helps to smooth, defrizz, and rebuild dry, chemically damaged hair back to a healthy, shiny state.
      We will contact you directly to help you find a salon offering this treatment.

    Can I be able to add hair extensions onto my hair after doing a keratin treatment 24 hrs ago

    • Keratin Questions on

      Hi Tanya,
      You can add extensions after a keratin treatment but the extensions will need to have the same treatment applied before they are attached so they will match your natural hair texture.

    I am considering a lasio keratin treatment. However, I’m concerned that the treatment may damage my hair instead of repair my frizz ( because of the 450 flatiron process )
    Any other recommendations?

    • Keratin Questions on

      Hi Veronica,
      Keraplast offers an intensive repair salon treatment that is heat activated called Hair Rescue. It contains Replicine Functional Keratin which is the closest in form to your own natural keratin. This treatment is not a straightening treatment but more of a smoothing treatment. It helps to repair and smooth dry, frizzy, and chemically damaged hair.
      This keratin is a mixture of oxidized keratin, intact keratin proteins, and keratin peptides. It acts like a zipper to seal hair fibers and cuticles making the hair stronger and healthier.

    I have curly hair and I want to use keratin to reduce the frizz but keep it curly. if I use keratin on my hair without using baby liss to straighten it, will this reduce frizz and treat my hair while maintaining my curls or it will have no effect at all?
