Promois™ WK-Q is a cationized derivative of hydrolyzed keratin.Thanks to its cationic character, it can adsorb to the damaged part of the hair, repair very effectively and improve texture. It also has anti-static properties. Keratin is one of the structural proteins that compose the hair, the nails and the stratum corneum of the skin. It makes up 80% of human hair. About its amino acid composition, it must be noted that keratin has plenty of cystine, the amino acid that forms a bond between the helix of the protein and thus provides physical resistance to the hair structure as well as moisture. This is why it is important to supply keratin regularly through hair care products. Promois™ series is a range of peptides and derivatives obtained through hydrolysis of natural proteins. It is developed and manufactured in Japan by SEIWA KASEI.
