Hydrolyzed keratin is essentially a large protein molecule that has gone through a chemical process that is broken down in a way that allows it to penetrate the hair cuticle. It moisturizes and conditions both skin and hair and also forms a film when used on the skin or nails.

What is HYDROLYZED KERATIN used for?

Hydrolyzed keratin is used in creams, lotions, moisturizers, nail creams as well as shampoos, leave on cream, conditioners, serums.
  • Hair care: It is used to smooth and moisturize the damaged hair cuticle. It fills cracks and eliminates frizz associated with dryness. It helps fill the minor gaps throughout the hair shaft, including its three layers known as the cuticle, cortex, and medulla. Filling these microscopic gaps with broken-down protein helps to strengthen hair's structure, thereby improving its overall elasticity. Hydrolyzed keratin minimizes the damaging effects of sun exposure, heat styling, chemical treatments, and combing hair - tangled tresses. It is used as an antistatic agent that reduces static electricity by neutralizing the electrical charge on the surface of hair. It conditions the hair and leaves them easy to comb, soft and shiny and/or gives volume, lightness and shine
  • Skin care: It is used as a humectant to keep the moisture intact and skin conditioning agent, to maintain softness, suppleness. It is also used as a film forming agent to produce a continuous film on the skin as well as nails
