K18 Hair Mask – Unisex Molecular Leave-In Treatment for Damaged Hair Repair

The K18 Hair Mask is an advanced leave-in molecular repair treatment designed to restore severely damaged hair in just 4 minutes. Powered by the patented K18PEPTIDE™, this innovative formula works deep inside the hair fiber to reconnect broken keratin chains and disulfide bonds caused by bleaching, coloring, chemical treatments, and heat styling.

Unlike traditional hair masks that only coat the surface, the K18 hair mask repairs hair at a molecular level, delivering long-lasting strength, elasticity, and softness. Suitable for all hair types, this leave-in treatment provides progressive results with continued use, helping maintain healthier, stronger, and more resilient hair.
