Investigations of keratins extracted from wool by reduction hydrolysis and by alkaline hydrolysis showed that their chemical compositions and secondary structures were similar to original wool. The keratin isolates were similar in amino acid, Amides I and II, and secondary structure to each other and to original wool.
Keratin is a protein found naturally in our hair. With our current lifestyle, hair tends to get more dry and loses natural keratin, because of pollution, heat, styling, coloring etc. To explain in a simple way, a keratin hair treatment infuses the vital element keratin back in to each strand of the hair. This helps to fill in the gaps in the hair cuticles, and once Keratin is infused in to the hair â hair becomes healthier, straighter and much easy to style. Keratin treatment eliminates the frizz factor from hair. Keratin treatment protects hair from damaging UV rays and humidity.
