Transform severely damaged hair with the K18 Pro Molecular Repair Hair Mask, a professional-strength, leave-in treatment engineered to reverse hair damage at a molecular level. Whether your hair has been compromised by bleach, professional color services, chemical treatments, or frequent heat styling, this advanced 4-minute treatment restores strength, softness, and elasticity.

Unlike traditional rinse-out hair masks that only offer temporary surface conditioning, the patented K18PEPTIDE™ technology works deep within the hair cortex to reconnect broken polypeptide chains and disulfide bonds, delivering true, lasting repair.
