Phytokeratine Reparative Shampoo is a sulfate-free, silicone-free shampoo. This creamy shampoo gently cleanses the most delicate, fragile hair. Inspired by cosmetic technology, Phytokeratine uses an injection of keratin to repair the inner hair cortex plus hyaluronic acid to intensely hydrate deep down in the hair fiber. This innovative technology revives the most damaged and brittle hair, repairs the effects of heat styling and chemical processes, and prevents breakage.
