Treat your hair to the very gentlest of cleanses with PURIFY, INNOluxe pre-treatment shampoo. The perfect start to a Stand-Alone or pre-perm treatment, PURIFY is designed to be super-kind to hair and (as you'd expect from INNOluxe) it's a sodium chloride and sulphate-free zone. With a pH just a little higher than the hair's, it lifts the cuticles as gently as possible, leaving it ready for the next stages of treatment.
