The COSRX PEPTIDE-132 Ultra Perfect Hair Bonding Shampoo is a salon-grade, bond-repairing shampoo designed to strengthen and repair damaged hair while also caring for the scalp. Its core ingredient is the patented PEPTIDE-132 complex, which works to repair hair’s inner structure.

Key features and benefits

• Bond repair: The proprietary PEPTIDE-132 complex, a tripeptide with a low molecular weight of just 384.9 Da, is engineered to penetrate the hair’s cortex and bind to weakened keratin structures. This helps to repair broken hair bonds, reduce breakage, and minimize split ends.
• Strengthens hair: By reinforcing the hair’s internal keratin structure, the shampoo improves the overall strength, elasticity, and resilience of each strand.
• Soothes the scalp: A blend of active ingredients, including caffeine, zinc PCA, and niacinamide, works to calm and hydrate the scalp. This helps reduce dryness, flakiness, and irritation.
• Boosts shine and softness: The formula contains nourishing ingredients like collagen, ceramides, and 18 types of amino acids to smooth the hair cuticles, resulting in a noticeably softer, smoother, and shinier finish.
