I love this shampoo it cleans your hair so well and leaves it smelling great! I can go longer in between shampoo's. The blue gel lathers nicely and has a clean, marine-like scent. It's sulfate- and paraben-free, so it's safe for all hair types even keratin- or color-treated hair. Unlike some sulfate-free formulas, it lathers well and gets hair squeaky clean with no residue. Fresh, clean, rich lather gently cleanses the hair and scalp. Marine botanicals and algae extracts combined with silk and wheat proteins smooth and hydrate the hair while providing protection against split ends.
