COSRX - PEPTIDE-132 Bonding Treatment - Conditioner Strengthening and Reconstructing Hair - 120ml

COSRX PEPTIDE-132 Ultra Perfect Hair Bonding Treatment 120ml

The treatment that repairs hair where damage actually lives. The COSRX PEPTIDE-132 Ultra Perfect Hair Bonding Treatment is a salon-grade Korean rinse-out hair treatment powered by the same patented PEPTIDE-132 technology as the Ultra Bonding Shampoo — a low molecular weight peptide with a precisely designed amino acid sequence that passes through the cuticle to reach the cortex, bonding specifically to weakened keratin areas and filling in the gaps where protein is missing.  This silky, cloud-like cream texture is fatigue-free, providing a professional-grade finish that leaves hair resilient and frizz-free with a refreshed citrus and woody scent. 

The nourishing formula blends collagen, amino acids, ceramides, biotin, and a complex of 7 lightweight plant-based oils to reinforce resilience and improve elasticity — restoring moisture balance, taming frizz, and creating a silky finish from roots to ends. Use it twice a week as the intensive repair step in the complete PEPTIDE-132 Bonding Trio, and the cumulative structural strengthening compounds with every single application.

Why it works:

• Patented PEPTIDE-132 (Tripeptide-132 HCl) — repairs keratin bonds to rebuild and strengthen the hair structure from within  — at just 384.9 Daltons, it is optimally sized to penetrate the cuticle and reach the cortex where the real structural damage resides

• 18 types of Amino Acids (Arginine, Serine, Glutamic Acid, Threonine, Leucine, Proline, Aspartic Acid, Isoleucine, Glycine, Phenylalanine, Alanine, Tyrosine, Lysine + 5 additional) — restores hair elasticity, strength, and moisture balance  by replenishing the complete protein building blocks of healthy keratin

• Soluble Collagen — contributes to increased softness and improved texture  sealing the hair surface for a smooth, light-reflecting finish after every rinse

• Hydrolyzed Vegetable Protein — improves resilience by filling in weak spots along the hair shaft, leaving hair smoother and easier to manage 

• 5 types of Ceramide (Ceramide NP, NS, AP, AS, EOP) — strengthens the hair's natural protective barrier to prevent future damage, sealing the cuticle and locking in every active ingredient after rinsing

• 7 Premium Plant Oils (Argan, Jojoba, Macadamia, Camellia Japonica, Olive, Grape Seed, Rice Bran) — encapsulate moisture, reduce frizz, and provide a beautiful shine  — each oil chosen for a specific conditioning function, delivering a combined result no single oil could achieve alone

• Oat Peptide (Avena Sativa) — smooths the cuticle surface, improves detangling, and adds natural softness and manageability

• Hydrolyzed Hyaluronic Acid — a low molecular weight HA that penetrates the hair shaft to deliver deep, lasting hydration without any heaviness or residue

• Sodium Hyaluronate — locks surface moisture in and maintains a smooth, frizz-free finish throughout the day

• Biotin (Vitamin B7) — strengthens hair fibres  from root to tip, supporting keratin infrastructure and reducing brittleness and breakage

• Panthenol (Pro-Vitamin B5) — delivers deep hydration, locks in moisture, and adds a natural-looking shine  while conditioning the scalp at the roots

• Niacinamide (Vitamin B3) — supports scalp comfort, strengthens the barrier, and contributes to overall hair vitality 

• Tocopherol (Vitamin E) — a powerful antioxidant that protects hair from external stress and UV-induced oxidative damage
  

• Laminaria Japonica (Seaweed) Extract — mineral-rich marine botanical that nourishes and revitalises each strand with ocean-derived trace elements

• Chamomile Flower Water (Anthemis Nobilis) — soothes scalp irritation and adds a gentle anti-inflammatory base throughout the treatment

• Free from SLS/SLES, parabens, phthalates, and animal-derived ingredients · No animal testing · Cruelty-free  · Made in Korea 🇰🇷

How to use: After shampooing with the COSRX PEPTIDE-132 Ultra Bonding Shampoo, gently squeeze out excess water and apply the treatment to the lengths and ends of the hair, avoiding the scalp.

Use twice a week for bond repair and split end treatment.  Follow with the COSRX PEPTIDE-132 Hair Oil on semi-wet hair for maximum repair, frizz control, and lasting shine.

Best for: All damage levels from mild dryness to severe chemical damage · Color-treated & bleached hair · Heat-damaged & chemically processed hair · Coarse, tangled & frizzy hair · Fine hair needing strength without weight · All hair types · Made in Korea 🇰🇷

Why Seoulma recommends it:

If the COSRX PEPTIDE-132 Shampoo is the daily foundation of the bonding system, the Treatment is the intensive weekly repair session that drives the cumulative transformation. Used twice a week alongside daily shampooing, it dramatically accelerates the structural rebuilding that PEPTIDE-132 delivers — because the treatment format allows the actives to sit undisturbed in contact with the hair for the full 3–5 minutes needed for the deepest cortex penetration.

The texture is one of the most immediately impressive things about this product. It applies as a rich, silky cream that melts on contact with wet hair — no dragging, no unevenness, no fighting with tangles. 

The 7-oil complex is also worth understanding as a carefully considered system rather than a list of premium-sounding ingredients. Argan handles frizz and shine. Camellia Japonica seals the cuticle edge. Macadamia restores softness to coarse, brittle hair. Jojoba mimics the scalp's natural sebum to balance moisture along the full hair length. Olive and Rice Bran add conditioning richness. Grape Seed provides lightweight antioxidant protection. Together they deliver a finishing result that feels genuinely luxurious — a deep natural gloss and silky softness that most treatments only achieve with heavy silicones, without any of the long-term buildup and weighing-down that silicones cause.

The complete COSRX PEPTIDE-132 Bonding Trio — Shampoo daily, Treatment twice a week, Hair Oil every day — is the most scientifically rigorous hair repair system we carry at Seoulma, and the one we recommend most confidently to customers dealing with serious structural hair damage. The results compound with every use, and the difference after four consistent weeks is the kind of transformation that makes customers wonder why they waited so long to try it.
