K18 Biomimetic Hairscience Leave-In Molecular Repair Hair Mask (150 ml / 5.0 fl. oz.)

Reverse hair damage in just 4 minutes with the groundbreaking K18 Biomimetic Hairscience Leave-In Molecular Repair Hair Mask (150 ml). Powered by the patented K18PEPTIDE™, this professional-grade treatment penetrates deep into the inner layers of hair to reconnect broken polypeptide chains and disulfide bonds. Unlike traditional conditioners and hair masks that only coat the outer layer, this leave-in formula permanently repairs damage caused by bleach, color treatments, chemical services, and high heat styling—restoring core strength, elasticity, and softness to all hair types.
