01 About This Product +

K18 Leave-In Molecular Repair Hair Mask is a targeted at-home treatment clinically formulated to reverse damage from bleach, color, chemical processing, and heat in just 4 minutes. Powered by the patented K18Peptide, this innovative formula penetrates deep into the inner layers of the hair shaft to reconnect broken polypeptide chains and restore natural strength and elasticity.

Unlike surface conditioning treatments that wash away, this leave-in peptide mask integrates seamlessly into the hair structure for lasting renewal across all hair types. It delivers restored softness, smoothness, and bounce, leaving hair looking and feeling renewed from the core outward.
