Can Keratin Protect Hair From Damage?


Damage makes your hair look dull and brittle and causes it to break off at the ends.  No one likes hair damage.  Unfortunately, protecting your hair can be a daunting task.  Caused by just about anything, including heat, chemicals, pollution, daily maintenance and styling, climate, environment, hard water or chemicals that may be found in your tab water. It can seem like your only option is to wrap your head in a silk bandage and never leave the house.

Each strand of your hair is covered in a protective cuticle layer that keeps the inner cortex of your hair hydrated and healthy. Can you guess what the protective layer is made of? If you Guessed Keratin you guessed correctly! When the cuticle layer is damaged, the tiny cells crack and separate, and the cortex is left unprotected. When the cortex dries up, hair becomes brittle and delicate.

So what is it that causes the cuticle to break and degenerate? A whole host of things actually. Heat form styling implements like hair dryers, curling irons, flat irons, hot rollers, cracks the cuticle and dries out the cortex. Chemical services like hair coloring, especially coloring servicing where you are lifting with high volume peroxide or bleach, relaxers, perms, harsh straightening systems, break down protein bonds in the cuticle and cause it to break.

Even if you avoid heat and chemicals, you can still damage your hair from friction. Combing or brushing, wrapping a hair tie around a ponytail and even the rubbing of your head against your pillow while you sleep. Yikes. Your hair’s breaking even while you sleep!

How can you protect your hair?

Short of sleeping standing upright in the middle of the room, there’s nothing you can do to completely avoid the things that cause hair damage. What you can do however, is prepare your hair to handle all the heat, chemicals and friction that gets thrown your way in the average day. Some products are capable of shielding your hairs’ cuticles. And the secret ingredient is… Keratin!

How can keratin protect hair?

Damage is caused by degradation of the keratin proteins in the cuticle. Clearly, we need to protect those proteins! Functional keratin proteins can be introduced to your hair through hair products and take over where your natural keratin is damaged.

And if your hair doesn’t have any damage, the keratin will form a sacrificial layer around the hair follicle. So when heat, chemicals and friction find your hair, the sacrificial layer will be damaged leaving your natural keratin intact and the cortex protected. Awesome defense!

Of course, you know by now that for keratin proteins to really get in there and do the job of natural keratin they need to mimic the form, sequence and function of your hair’s keratin proteins. Replicine functional keratin is the only available protein that can do this. Always check the label before you buy!

    I believe I have hard water where I live, that is causing my ends to split and crack more than normal. i have vry curly har and take very cook care of it, no dye or heat, so this seems like the only reason. I have never done keratin and I was considering it as i want to protect my hair from further damage. I am wondering if keratin will protect my hair from hard water? and i am wondering what effects hard water may have on keratin. thank you!

    i recently straightened my hair. now i want to use KERATIN REPAIR MASK to prevent my hair from getting damaged. but i do not know how will i apply it. please guide me through.

      Hi Fabliha,

      I think that you are referring to the Lolane keratin repair masks? The bottle should give you a set of instructions on how to best apply it. However there are instructions on the internet. Basically you apply it as you would a rinse out-conditioner, after a salt free shampoo, making sure that you rinse it out afterwards.

      It seems impossible to obtain the full list of ingredients for these products via the internet. However, according to the manufacturer, it contains hydrolysed keratin and oxidised keratin – both of which are good for your hair.

      But any home applied treatment won’t be as effective as a salon applied Keratin Hair Rescue treatment such as the BHave Hair Rescue or the Keraplast Hair Rescue Treatment with Replicine™ Functional Keratin®, or the Awapuhi Wild Ginger Keratriplex treatment.

      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 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.

    I recently bought a conditioner and a spray on treatment with keratin. I have a curly perm. Will this hurt my perm and make it straight?

    • Keratin Questions on

      Hi Paula,
      Keratin won’t hurt your perm. However you need to check the other ingredients in the spray-on treatment. If it’s a smoothing treatment it many contain chemicals that will interfere with the crosslinking in your hair and therefore affect your curls.

    I was thinking about getting keratin. I have been wondering what exactly keratin does. I don’t want my curls to go away or disappear. I’m just want something that can moisturize my hair and prevent it from being dry nappy and frizzy, but not my curliness subside or become less curly. Is keratin what i should use? Will it do these things?
    What exactly does keratin do?

    • Keratin Questions on

      Hi Mya,
      Keratin itself can provide your hair with the great benefits that you are seeking. If you have a keratin based hair rescue treatment it won’t alter your curls but it will provide better shine, volume and hair health. However you will need to be careful that you are not sold a Keratin hair straightening treatment which will damage your hair and remove your curls. The treatments that will provide keratin without the straightening process are the Bhave Rescue, the Paul Mitchell Awapuhi Wild Ginger Keratriplex treatment, and the Keraplast Hair Rescue Treatment. The BHAVE range is available in salons in Australia and Awapuhi is available in many countries. Keraplast have recently added a salon locator to their website and you can find it at
      http://www.keraplast.com/component/option,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 stockist nearby – you could ask your salon to contact Keraplast at http://www.keraplast.com/contact and Keraplast will be happy to supply them the Hair Rescue Treatment and directions so that they can undertake the treatment with you.

    My daughter had the keratin dine to her hair and a week later her hair is falling out.it has been a month now and it is dry and damaged in still falling out in different spots what can I do ?…..

    • Keratin Questions on

      Hi Jenn,
      To answer your question I have to ask you one.
      Do you have a salon you trust? If so Rescue is on the way.
      Keraplast has an intensive repair conditioner called Hair Rescue. It helps to restore dry, frizzy, and chemically damaged hair back to a healthy, shiny state. The treatment takes about 30 minutes.The Hair Rescue contains the unique Replicine Functional Keratin comprised of oxidized keratin, intact keratin proteins, and keratin peptides. This keratin is the closest in form to your own natural keratin.
      If your daughter’s hair is truly damaged it may take a few treatments.
      Is the hair falling out or breaking?
      The Hair Rescue will not keep the hair from falling out but will help strengthen existing hair.
      When the hair falls out it is more of a medical concern but if it is breaking off due to brittleness then the Hair Rescue product can help.
      Contact mary@keraplast.com for further assistance.
