COSRX Peptide-132 Hair Bonding Shampoo — 13.52 fl oz daily scalp treatment that repairs and strengthens damaged hair

COSRX PEPTIDE 132 Hair Bonding Shampoo is a daily cleansing and strengthening shampoo that repairs weakened keratin bonds while calming dry, itchy, or flaky scalps.

This lightweight, salon-inspired formula uses COSRX’s proprietary PEPTIDE-132 tripeptide complex to target broken keratin structures and reinforce each strand, helping hair feel stronger and look smoother after regular use. It removes buildup gently, supports scalp comfort, and is designed to pair with the PEPTIDE-132 Hair Treatment and Hair Oil for a complete hair-bonding routine. Free from SLS/SLES, parabens, phthalates and animal-derived ingredients, it’s suitable for routine use on sensitive scalps and damaged hair types.

How does PEPTIDE-132 help repair damaged hair?

The PEPTIDE-132 complex is formulated to bind to weakened keratin and assist in rebuilding structural integrity along the hair shaft. Instead of coating hair with heavy silicones, the peptide targets internal bonds to reduce breakage and improve manageability over time.

• Tripeptide technology that interacts with damaged keratin.
• Reinforces weak points to minimize split ends and snapping.
• Lightweight action that avoids a greasy finish.

Will this shampoo help a dry, itchy, or flaky scalp?

This shampoo combines gentle cleansing with calming, moisture-supporting ingredients to soothe irritation and reduce flakiness. It balances the scalp environment without stripping natural oils, making it a good daily option for sensitive or disrupted scalps.

• Removes buildup that can worsen itch and flakes.
• Helps restore moisture balance for less dryness.
• Safe for everyday use on sensitive scalps thanks to mild surfactants.

How should I use the PEPTIDE-132 shampoo for best results?

Use the shampoo as your regular daily cleanser, then follow a targeted routine to maximize bond repair. Incorporating the full PEPTIDE-132 trio — shampoo, treatment mask, and hair oil — delivers cumulative benefits for strength, reduced frizz, and improved shine.

• Wet hair thoroughly and massage a small amount into scalp and lengths; rinse well.
• Use the PEPTIDE-132 Hair Treatment twice weekly to rebuild bonds and treat split ends.
• Apply the PEPTIDE-132 Hair Oil to semi-dry hair to seal cuticles, reduce frizz, and add shine.

Is this shampoo free from harsh ingredients and cruelty-free?

Yes — the formula avoids common irritants and animal-derived components while being developed without animal testing. It’s a cleaner alternative for those who prefer conscious beauty options but still need targeted hair repair.

• Formulated without SLS/SLES, parabens, or phthalates.
• No animal-derived ingredients; cruelty-free development.
• Lightweight, everyday formula suited to sensitive hair and scalp.

Who is this for: COSRX PEPTIDE 132 Hair Bonding Shampoo is suited for people with dry, brittle, color‑treated, or chemically processed hair who want to reduce breakage and soothe scalp discomfort. It also fits anyone seeking a gentle daily shampoo that complements an intensive bond-repair routine with treatment and oil steps. If you prioritize cleaner ingredient lists and targeted peptide repair rather than heavy smoothing agents, this product is designed for your ongoing hair maintenance.
