Hydrolyzed silk protein replenishes the hair with cysteine, which is one of the 4 amino acids needed to produce keratin.
Anti-breakage
Hydrolyzed silk protein has a low molecular weight and has greater ability to infiltrate the hair strands. It improves elasticity against breakage and forms a protective barrier on the hair.
Protection & moisturizer
Hydrolysed silk protein dries to form a transparent crystalline protective film. The protective film seals the hair cuticle, increasing combability (detangling) and shine, and acts as a moisturizer by preventing drying.
