I thought I would share this information about protein in hair products with you. I have found it on several hair boards and I do not know who the original author is.
Protein can be found in many hair products. All proteins are strengthening to some degree but here are more specific characteristics of these proteins:
Collagen Proteins – known for increasing elasticity in the hair.
Silk Proteins – known for softening the hair.
Wheat Proteins – a moisturising and strengthening protein. Known for increasing the hair’s ability to maintain and receive moisture.
Vegetable Protein – Vegetable protein absorbs more easily into the hair shaft (than animal protein) and does not create build-up, leaves the hair very shiny, radiant and healthy.
Animal Protein – Animal protein breaks down into fatty acids, which coats the hair and can create residual build-up.
Silk Amino Acids/Protein – Natural silk is the strongest, natural fibre known to mankind. Discovered in Japan, it has been used for centuries in all kinds of products that require durability. Silk has a tiny molecule that can penetrate the entire hair shaft deeper than all other proteins without adding any weight and leaving the hair feeling clean and non-greasy.
Keratin Protein – responsible for keeping the hair strong and pliable. This is the strongest of the proteins found in hair products and is actually the one hair is made from. Keratin Protein re-structures hair that has been damaged or broken down by chemicals. It helps to replace the amino acid cysteine which is the main one lost during chemical processing. This is what is known as a heavy duty protein. You can identify it as the following:
* Keratin Protein – this will re-structure and strengthen the hair cuticle.
* Hydrolyzed Keratin Protein or Keratin Amino Acids – this means that the Keratin molecules have been broken down and are small enough to go beyond the cuticle and penetrate the hair shaft. It will strengthen all 3 layers of the hair.
* Hydrolyzed Human Hair Keratin – This is an exact match for the keratin your hair has (or has lost due to chemical processing). This is the highest quality and most potent keratin that can be used in hair products.
You can read this post for more on protein as well as the importance of protein/moisture balance.
