Keratin Shampoo Keratin restructuring shampoo is a keratin restructuring product with detangling, polishing, and immediate strengthening action. Formulated with a mix of gentle surfactants with low dermatological impact, derived from sugars. It deeply cleanses by removing all residues from the hair without impoverishing the essential hydrolipidic barrier of the hair and scalp. It leaves hair soft, shiny, and smooth. Hydrolyzed keratin, of which the shampoo is particularly rich, has a high restructuring power, as this protein is the main structural component of hair.
