"Hair definitely feels softer and shinier since using"
The K18 Leave-In Molecular Repair Mask is a revolutionary, patented treatment that reverses hair damage in just four minutes. This leave-in mask is powered by the K18PEPTIDE™, a bioactive peptide that travels to the innermost layers of the hair to reconnect broken keratin chains, providing lasting repair from the inside out, not just a temporary conditioning effect. Clinically proven to reverse damage from bleach, colour, chemical services, and heat, it restores the hair's strength, softness, smoothness, and bounce, renewing hair to a near-virgin state.
