Restore your hair's strength and resilience with this leave-in treatment mask, clinically proven to reverse damage in just four minutes. Suitable for all hair types, it repairs the effects of bleach, colour, chemical services, and heat styling to bring back softness, smoothness, and natural bounce.
Powered by the patented K18PEPTIDE™, this highly concentrated formula is engineered with the precise size and structure needed to penetrate the innermost layers of the hair.
