The Cosrx Peptide-132 Ultra Perfect Hair Bonding Treatment is a professional-grade, intensive repair mask designed to revitalize dry, damaged, and chemically treated hair. Powered by the patented PEPTIDE-132™ complex, it works to reinforce weakened keratin bonds, effectively mending split ends and improving overall hair elasticity. This rich, silky formula is infused with collagen, 18 amino acids, ceramides, and a blend of 7 nourishing plant oils (including Argan and Jojoba) to provide deep hydration and tame frizz. Regular use transforms brittle, dull strands into smooth, resilient, and luminous hair, delivering a healthy, salon-quality finish from root to tip.
