Promois WS-HQ is a cationized derivative type of hydrolyzed soy protein. It can adsorb to the damaged hair effectively and provide anti-static character because of its cationic character. Soy protein is distinct from animal proteins such as collagen and keratin in that it is composed of 30% glutamic acid and aspartic acid. Like collagen, it brings high moisturizing property, but it brings a different texture. Additionally, it produces a moist feeling and prevents unmanageable hair. Promois series is peptide, obtained through the hydrolysis of natural proteins, and their derivatives.
