COSRX Peptide 132 Hair Bonding Shampoo — 13.52 fl oz Daily Repair for Dry, Damaged Scalp & Split Ends

This shampoo is formulated to remove buildup gently while rebuilding weakened keratin bonds to reduce breakage and improve hair resilience. Designed for everyday use, it targets signs of damage such as split ends, rough texture, and scalp irritation without harsh sulfates or parabens. Paired with the rest of the PEPTIDE-132 trio, it becomes part of a complete regimen for stronger, smoother hair.

How does PEPTIDE-132 repair broken hair bonds?

The proprietary PEPTIDE-132 contains a tripeptide complex that seeks out weakened keratin and helps reattach protein structures along the hair shaft. This action reduces breakage and helps strands withstand mechanical stress from brushing and styling. Over time, hair feels denser and looks healthier as fewer ends split and fray.

• Tripeptide complex targets and reinforces keratin bonds.
• Reduces mechanical breakage and visible split ends.
• Improves strand elasticity and smoothness with regular use.

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

Yes — the formula is designed to calm and balance the scalp while providing cleansing that doesn't strip natural oils. It removes excess buildup that can aggravate flaking and leaves the skin feeling refreshed. Its gentler surfactant base helps maintain hydration, reducing tightness and itchiness.

• Gently removes sebum and product residue that worsen flaking.
• Supports a more comfortable, less irritated scalp environment.
• Free from SLS/SLES and harsh sulfates to minimize dryness.

How should I use this shampoo for best results?

Use daily to cleanse hair and scalp, then follow a targeted routine with the PEPTIDE-132 Treatment and Hair Oil for repair and shine. Apply shampoo to wet hair, lather gently, and rinse thoroughly; repeat if needed. For intensive repair, apply the PEPTIDE-132 Hair Treatment twice weekly and finish on damp hair with the PEPTIDE-132 Hair Oil to seal and smooth.

• Daily: PEPTIDE-132 Shampoo to cleanse and strengthen.
• Twice weekly: PEPTIDE-132 Hair Treatment for bond repair.
• Finish: PEPTIDE-132 Hair Oil on damp hair to reduce frizz and add shine.

Is this shampoo suitable for sensitive scalps and clean-beauty routines?

Formulated without parabens, phthalates, SLS/SLES, and animal-derived ingredients, it fits many clean-beauty preferences. The milder surfactants and calming actives make it a reasonable option for reactive or sensitive scalps, though patch testing is recommended if you have extreme sensitivity. COSRX also avoids animal testing in this formula.

• Free from common irritants like SLS, parabens, and phthalates.
• Vegan-friendly formulation without animal-derived ingredients.
• Recommended pairing with other PEPTIDE-132 products for optimal results.

Who is this for: COSRX PEPTIDE 132 Hair Bonding Shampoo is aimed at anyone with dry, damaged, or chemically treated hair who wants to reduce breakage and soothe scalp discomfort. It's well suited for people seeking a daily, clean-beauty shampoo that supports protein rebuilding and pairs easily with concentrated treatments for visible improvement in texture and manageability.
