K18 Leave-In Molecular Repair Hair Mask – Patented K18Peptide Treatment, Reverses Damage in 4 Minutes from Bleach, Color & Heat

K18 Leave-In Molecular Repair Hair Mask

Powered by the patented K18Peptide™, this leave-in treatment works on a molecular level to reverse hair damage in just 4 minutes — no rinsing required. Unlike traditional deep conditioners that coat the hair's surface, K18Peptide travels deep into the hair's inner layers to reconnect broken keratin chains, restoring strength, elasticity, and bounce from bleach, color, chemical services, and heat styling. Results are immediate and don't wash away with shampoo.
