K18 Leave-In Molecular Repair Hair Mask 50ml

Four Minutes to Transformed Hair

The K18 Leave-In Molecular Repair Hair Mask is a clinically proven, no-rinse treatment that works at the molecular level to reverse damage caused by colouring, bleaching, heat styling, and everyday stress. Powered by the patented K18Peptide™, it reconnects broken keratin chains to restore hair's natural strength, elasticity, and vitality — in just four minutes.

The Science Behind K18Peptide™

At the heart of this treatment is K18Peptide™ — a bioactive molecule engineered to mimic the natural structure of hair. Unlike surface-level conditioners, K18 penetrates to the deepest cortical layer, repairing polypeptide chains that conventional treatments cannot reach. The result is a lasting transformation that does not wash out.
