K18 Leave-In Molecular Repair Hair Mask – 4-Minute Damage Repair for Dry, Frizzy & Color-Treated Hair is a high-performance leave-in treatment designed to repair damaged hair at a molecular level and restore strength, softness, and elasticity.

It is powered by K18Peptide technology, which helps reconnect broken keratin chains within the hair structure caused by chemical treatments, heat styling, and mechanical damage. Unlike traditional masks that only coat the hair, this treatment works inside the hair fiber to improve overall hair health and resilience over time.

The lightweight, non-greasy formula is applied after shampooing and works in just 4 minutes, making it a quick and effective step in a modern hair care routine.
