Juvexin™ Hair Taming System. Shampoos and Conditioners contain Juvexin™ Hair Taming System, a unique organic and active keratin that unlike over processed hydrolyzed keratin has a structure very close to the hair keratin that binds and coats the hair. It protects it from damages, maintaining and enhancing the shine and softness of the hair after every wash. It is also free of Sodium Chloride, a salt that make shampoos harsh for the eyes, and strip the color dye of your hair. Due to this it is specially recommended to be used after the Juvexin™ Hair Treatment.
