Looking for the ultimate molecular repair for severely damaged hair? The K18 Leave-In Molecular Repair Hair Mask is a clinical-strength peptide treatment that repairs hair at the innermost layer. Powered by the patented K18PEPTIDE™, it reconnects broken polypeptide chains and disulfide bonds damaged by bleaching, color, heat styling, and chemical treatments in just 4 minutes.
Works fast at a molecular level to restore strength, elasticity, and softness instantly.
Repairs damage caused by bleach, hair dye, chemical services, and extreme heat.
Does not wash out with shampoo; provides permanent structural repair with long-term results.
Restores hair’s natural elasticity and smooth shine without weighing down strands.
Conditioners leave a barrier on the hair shaft that prevents the K18PEPTIDE™ from penetrating into the inner core to repair broken bonds.
Use it for 4 to 6 consecutive washes initially, then transition to maintenance mode by applying it every 3 to 4 washes.
