Silk Amino Acids contain 3 of the smallest amino acids (alanine, glycine and serine) and have a chemical composition that is very close to that of human skin and hair making them a wonderful source of nourishment and maintenance. Silk Amino Acids are highly hygroscopic and have excellent moisture binding ability, protecting hair from moisture loss.
They can penetrate very deeply into the hair cortex (hair cuticle and hair shaft), drawing moisture into these areas, improving hair hydration. Even when employed in low concentrations, the use of Silk Amino Acid can have a noticeable effect on the appearance of hair.
