COSRX Peptide 132 Hair Bonding Shampoo — 6.76 fl oz, sulfate-free daily scalp treatment that repairs and strengthens damaged hair

COSRX PEPTIDE 132 Hair Bonding Shampoo is a gentle daily cleanser that repairs weakened keratin bonds, soothes dry or flaky scalps, and strengthens damaged hair.

This sulfate-free shampoo combines COSRX’s patented PEPTIDE-132 tripeptide complex with a scalp-friendly cleansing base to remove buildup while targeting broken hair bonds. It’s designed for everyday use and plays a central role in the PEPTIDE-132 Hair Bonding Trio, helping minimize breakage and improve manageability without harsh surfactants or animal-derived ingredients.

How does this shampoo repair damaged hair bonds?

The formula’s Tripeptide complex is engineered to interact with weakened keratin and reinforce strands where they’re most vulnerable. Rather than coating hair with heavy silicones, it supports internal bond strength to reduce split ends and improve elasticity over time.

• PEPTIDE-132 targets keratin breakage and helps reseal compromised bonds.
• Supports strand integrity to reduce hair breakage and brittleness.
• Lightweight conditioning helps preserve natural movement and shine.

Will it help a dry, itchy, or flaky scalp?

The shampoo includes calming, hydrating ingredients and avoids harsh sulfates that can strip the scalp, so it helps normalize scalp condition with routine use. Users often notice less visible flakes and reduced dryness when combined with the complementary treatment and oil.

• Balances moisture without heavy residue that can worsen flaking.
• Gentle cleansing removes buildup that can irritate the scalp.
• Formulated to be suitable for sensitive scalps and daily use.

How should I use it for the best bond-repair results?

For optimal results, use the shampoo daily to cleanse and prepare hair for intensive treatments. Incorporate COSRX PEPTIDE-132 Hair Treatment twice weekly and finish with the Hair Oil on damp hair to lock in repair benefits and tame frizz.

• Daily: COSRX PEPTIDE-132 Shampoo to cleanse and strengthen.
• Twice weekly: PEPTIDE-132 Hair Treatment to bond split ends.
• After shower: PEPTIDE-132 Hair Oil on semi-wet hair to seal and add shine.
