What sort of products can I find keratin in and why is it used?


So now you know what keratin is, you probably want to know where you can find it and what it can do for your hair, right?


The good news is Keratin is found in a range of hair shampoos, conditioners, treatments for damaged and colored hair; but you’ll have to do some careful ‘label checking’ next time you’re shopping.

The purest type of keratin is the one we discussed in the last blog post – grown right  in the country of the Lord of the Rings’ ‘Middle Earth’ – yep little old New Zealand from their most common woolly mammals – sheep!

So wherever you shop, whether in the supermarket, drug store or at the hairdresser – what you want to look for is products that contain (the purest stuff) Replicine Functional Keratin technology.  This sometimes appears on the label as Keratin or oxidized keratin.

Some products sound like they contain Keratin (they use keratin in their product name to falsely mislead you, the consumer) but they don’t actually list keratin in their ingredients, or may only have hydrolyzed keratin, which is so far from being real keratin that it doesn’t do much.

So why is it used? And what are the benefits?

Replicine Functional Keratin technology contains a purified form of keratin intermediate filament protein manufactured purely, as mentioned before, from New Zealand sheep wool. The intermediate filament protein is the protein that gives natural hair fibers their strength.

This protein is really clever in how it works:

  1. It coats the outside of the hair shaft in a shield which protects from nasty pollutants.
  2. It penetrates the hair fibers and starts working to heal hair from the inside out.

The combined action makes it so effective – it’s basically a liquid form of hair!

As well as healing your hair from the inside out, it takes on the damage itself so your hair doesn’t! How cool is that?!

The nasty environmental pollutants that damage hair include cigarette smoke, UV radiation, and sulfur dioxide gas (from car and truck exhaust fumes).

It’s especially important to use Replicine Functional Keratin technology after chemically straightening hair, because the straightening agent formaldehyde destroys the hair structure in the straightening process and the keratin is what ‘heals’ it again.

In the next blog post we’ll discuss exactly how to decipher that scientific jargon on the back of your hair care products…so stay tuned!

    I want to buy Replicine! Where can I find it???

    It would be nice to get an answer to your question. I am asking the same thing but all I seem to get is an explanation on how it works and what to look for in the ingredients. I looked at all the shampoes and conditioners in 2 stores, not one of them had Replicine Functional Keratin in it.

    I can find it on-line for 100 + That is ridicules.

    I cannot verify what kind of Keratin is in this product until I go there and read the ingredients. Hope it is the real thing and not Hydrolized Keratin because it is useless.

    • Keratin Questions on

      When you look at the ingredients list of this product you see Keratin, Hydrolyzed Keratin, Oxidized Keratin. The Keratin and Oxidized Keratin components are the right forms of keratin providing good performance.

    You can also find Keratin and Oxidized Keratin in Paul Mitchell’s new Awapuhi line of products and their Keratriplex Treatment! :-)

    I stay in South Africa,where can I find these products and does Kerastase products also contain the correct type of Keratin?

    • Keratin Questions on

      Unfortunately Replicine Functional Keratin is not yet available in South Africa. Kerastase products do not contain any keratin of any type. The name often makes people think that it should contain keratin, but unfortunately that is not the case.

    Very happy with this product, buying my 2nd bottle. Makes my curly wavy hair straighter, healthy and shiny, my hair was looking damaged before I tried this and now it looks great.

    I live in North America. I was super excited about the new Suave keratin infusion smoothing shampoo and conditioner, but after reading that article on real and “fake” keratin I found out the suave thing uses Hydrolized Keratin! It got really good reviews but I don’t know if it will be as good as real keratin. Is there any cheap local-ish shampoo and conditioner with real keratin?

    • Keratin Questions on

      Awapuhi wild ginger, from Paul Mitchell, contains keratin and oxidized keratin, these are real keratins that provide great performance and is available widely in North America. Also look out for treatment products with Replicine Functional Keratin, this is the latest and most concentrated form of the real keratin technology ever produced.

  9. Wonderful post but I was wanting to know if you could
    write a litte more on this topic? I’d be very grateful if you could elaborate a little bit further. Thank you!

      That’s a bit of an open ended question…there is a great deal that could be said on keratins, products that contain keratins and what they can do for you! Perhaps it would be helpful to talk a bit about the functionality of the different keratin ingredients that are available out there?

      “Hydrolyzed Keratin” is from a process where a keratin source is treated with a chemical such as caustic, which breaks up the keratin into small water soluble components known as peptides. These will contain a few – usually less than 10- amino acids linked together. Amino acids are the basic building blocks of all proteins and there are 20 that are most common. The peptides are small so able to transfer easily across the skin and get into the crevices in your hair. They will also draw water into your skin with them so acting as a “humectants”. But, because of the process by which they have been extracted from the Keratin source, they will form only weak attachments with the proteins in hair and have lost much of their original functionality.

      In contrast Replicine™ Functional Keratin® is produced by patented processes that retains the functionality of the keratins. Replicine™ contains three broad groups of Keratins which are listed in the ingredients as: Keratin, Hydrolyzed Keratin and Oxidized Keratin, or as subsets of these three groups. The” Keratin” has been extracted from New Zealand sheep wool by a gentle process that retains the full length of the proteins and their functionality. These large proteins, also known as Intermediate Filament proteins, have fascinating properties and are able to form films and realign with each other back into the helical forms that are present in keratin structures. They are great for providing a protective layer to hair and skin. And because the functionality of the cysteine amino acids has been retained in the keratins they are able re-crosslink with your hair to form durable bonds that can help with small cracks and tears in the shaft and in the protective cuticle layer of your hair.

      Like “Hydrolyzed Keratin” extracted via other processes the Hydrolyzed Keratin that is the second group in Replicine™ Functional Keratin®, is small and able to penetrate into your skin and the hair shaft drawing in moisture along with it. However in contrast to conventional Hydrolyzed Keratin Replicine™ Hydrolyzed Keratins still retains the functionality of the cysteine amino acids and so are able to crosslink with the keratin of your hair.

      The Oxidized Keratin within Replicine™ has been shown through science research, to have some amazing properties. This ingredient is used in wound healing products as it accelerates the rate of healing through increasing activity of keratinocytes in the wound. It has also been shown to promote the production of collagens 4 and 7, which are situated in the skin at the dermal-epidermal junction. This helps to repair and strengthen the junction, and incidentally reversing the development of wrinkles which begin at this point through the aging loss of collagen 4 and 7. Oxidised Keratin has retained the amino acid sequence of the original keratin source and is able align with the proteins in hair forming what are known as ”hydrogen bonds” and “salt bridges” to help repair to give hair back its strength and shine.

      Collectively, these keratin types within Replicine™ Functional Keratin® promote the production of glutathione within the skin, which is the cells own master antioxidant which helps counteract the impacts of environmental stress and aging.

      That’s a fairly whirlwind description of the different types of keratins and their activity in skin and in hair, as discovered through the recent research undertaken with Replicine. If you have any more questions please come back to us!

    Care of the hair and care of the scalp skin may appear separate, but are actually intertwined because hair grows from beneath the skin. The living parts of hair (hair follicle, hair root, root sheath, and sebaceous gland) are beneath the skin, while the actual hair shaft which emerges (the cuticle which covers the cortex and medulla) has no living processes. Damage or changes made to the visible hair shaft cannot be repaired by a biological process, though much can be done to manage hair and ensure that the cuticle remains intact..’

      You are quite right that damages to the hair shaft cannot be repaired by a biological process. However it is possible to “glue” small splits in the shaft and cuticle with an appropriate material. Replicine™ Functional Keratin® has been extracted from clean New Zealand sheep wool and is the same as the keratins in your hair. Unlike other extraction processes the Replicine™ process is able to extract the long proteins intact, retaining the amino acid sequences, while also maintaining the crosslinking functionality of the cysteine that holds the proteins together in your hair naturally. These properties allow the Replicine™ proteins to align with the proteins in your hair and form durable bridges across spaces where the hair shaft has begun to come apart. The Replicine™ Functional Keratin® will also coat the hair shaft crosslinking with the cuticle of your hair to provide a smooth and glossy protective layer; helping to add body and shine to your hair. But unlike silicones these proteins are chemically identical to your hair so do not interfere with the transfer of dyes or conditioning agents.

    I have stopped using hair relaxer on my hair in the past 6 months with the aim of going natural , but being an African my hair is all so thick ,difficult to comb or manage which products would you recommend I use taking into consideration that I want the hair to be soft ,smooth and easy to manage without getting a perm thank you

    My hair is very curly and I use a leave in product with keratin 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.
