Keratin serum is formulated with Hydrolyzed Keratin. Keratin is a protective protein differed from other protein in that it is rich in cystine, which cross-links covalently into disulfide bonds and counts for it’s unique strength and protective qualities. Keratin serum is particularly useful for waving hair. Adding it to the product not only protects the hair, but also increases the amount of cystine available to the hair, minimizing damage and increasing tensile strength.
