Molecular Repair That Works
The K18 Leave-In Molecular Repair Hair Mask is a patented peptide-powered treatment that reverses hair damage at the molecular level. Unlike traditional masks that only coat the hair, K18’s bioactive K18Peptide™ travels deep into the inner cortex to reconnect broken keratin chains caused by bleaching, coloring, heat, and chemical services.
Clinically proven to restore strength, softness, and elasticity in just 4 minutes, this no-rinse treatment works across all hair types—making it a must-have for anyone recovering from damage or looking to protect their hair from future stress.
