COSRX PEPTIDE-132 Ultra Bonding Shampoo 200ml

The shampoo that repairs hair from the inside out. The COSRX PEPTIDE-132 Ultra Bonding Shampoo is built around a world-first breakthrough in hair science — a patented peptide engineered using AI molecular modelling technology that is absorbed not only into the cuticle but also into the cortex, which plays an important role in the strength and elasticity of the hair.  This is not surface-level repair. PEPTIDE-132 fits into the keratin like a puzzle piece, filling in the gaps where protein is missing and strengthening the structure of weakened keratin — restoring hair to a healthy state from its core. 

Powered by patented PEPTIDE-132, this bond-repair formula helps reinforce protein and keratin bonds to improve resilience and smoothness in damaged strands — enriched with collagen, ceramides, and amino acids to deliver hydration and nourishment that restores softness and shine.] And it does all of this while gently and thoroughly cleansing — its rich lather cleanses without residue, leaving both scalp and hair feeling fresh and soft. 

Why it works:

• Patented PEPTIDE-132 (Tripeptide-132 HCl) — 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  — the more you use it, the stronger and more resilient your hair becomes
  

• 18 types of Amino Acids (Arginine, Serine, Glutamic Acid, Threonine, Leucine, Proline, Aspartic Acid, Isoleucine, Glycine, Phenylalanine, Alanine, Tyrosine, Lysine + 5 additional) — the complete protein building blocks of healthy keratin, replenishing exactly what heat, colour, and environmental stress strips away from each strand

• Hydrolyzed Vegetable Protein & Low-Molecular Collagen — recharge hair protein and support keratin bonding  at every structural level of the hair shaft, from cuticle to cortex

• 5 types of Ceramide — seal the hair cuticle and lock in moisture, preventing further protein loss and environmental damage between washes

• Oat Peptide (Avena Sativa) — a natural conditioning peptide that smooths the cuticle surface, reduces frizz, and improves overall manageability and softness\

• Niacinamide — rejuvenates and hydrates the scalp, reducing itchiness and excess oil  while brightening any uneven scalp tone

• Caffeine — addresses flakes, oiliness, and irritation  by stimulating scalp microcirculation and energising hair follicles for a visibly healthier growth environment

• Zinc PCA — regulates excess sebum production and provides antimicrobial scalp protection, reducing the conditions that lead to dandruff and scalp sensitivity\

• Piroctone Olamine — a clinically proven anti-dandruff active that eliminates scalp flaking and itching without the harshness of traditional anti-dandruff shampoos

• Biotin (Vitamin B7) — reinforces the hair structure from root to tip, supporting keratin infrastructure and reducing the brittleness that leads to breakage and shedding
• Macadamia Seed Oil & Grape Seed Oil — lightweight, non-greasy plant oils that condition the hair shaft and add a subtle natural gloss without weighing fine hair down

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

• Chamomile Flower Water (Anthemis Nobilis) — soothes scalp irritation and redness, providing a gentle anti-inflammatory base for sensitive scalp types

• Tocopherol (Vitamin E) — antioxidant protection against environmental free radical damage and oxidative stress on the scalp

How to use: Apply a generous amount to wet scalp and hair. Gently massage into the scalp using circular motions, then work through the lengths of the hair until fully lathered. Rinse thoroughly with lukewarm water. For best results, use daily and follow with the COSRX PEPTIDE-132 Hair Treatment twice a week and the COSRX PEPTIDE-132 Hair Oil on semi-wet hair to lock in moisture, tame frizz, and deliver long-lasting shine. 

Best for: All damage levels from mild dryness to severe chemical damageThose seeking both hair repair and scalp care in one step · Color-treated & bleached hair · Fine to coarse hair · All hair types · Made in Korea 🇰🇷

Why Seoulma recommends it:

COSRX built its reputation on one principle — take what works in skincare science and apply it rigorously to whatever it touches next. With the PEPTIDE-132 line, that principle has produced something genuinely new in the hair care category. Most bond-repair shampoos borrow the language of skincare without delivering the science. COSRX has actually done the science — developing a patented peptide using AI molecular modelling, verifying its absorption into the hair cortex in laboratory cross-section analysis, and registering an official Korean patent for the technology. That level of rigour is rare in hair care at any price point.

We recommend it as the daily foundation of a serious K-Beauty hair repair routine — and particularly for anyone who has been frustrated by bond-repair products that deliver short-term improvement but no lasting change. Pair it with the COSRX PEPTIDE-132 Hair Treatment twice a week and the Hair Oil as your daily finishing step for the complete bonding system that consistently delivers the strongest results.
