K18 Leave-In Molecular Repair Hair Mask – 50 ml (Bond Rebuilding Treatment)

Product Overview

K18 Leave-In Molecular Repair Hair Mask is an innovative, professional-grade hair treatment designed to repair damaged hair at the molecular level. Powered by K18’s patented peptide technology, this leave-in mask works deep within the hair’s inner structure to reverse damage caused by chemical treatments, heat styling, and environmental stress.

Unlike traditional masks that only coat the hair, K18 restores broken keratin chains, helping hair regain its original strength, softness, and elasticity in just minutes—without weighing it down.

Advanced Molecular Repair Technology

K18Peptide™

At the heart of this formula is the patented K18Peptide™, a biomimetic peptide that penetrates deep into the hair cortex. It reconnects broken keratin chains and restores strength lost from:

• Bleaching and coloring

• Chemical straightening and perms

• Heat styling tools

• Mechanical damage from brushing and styling

This molecular repair process delivers long-lasting results that do not wash out.
