COSRX Peptide 132 Hair Bonding Shampoo 13.52 fl oz — Sulfate-free daily repair to strengthen and soothe scalp

COSRX PEPTIDE 132 Hair Bonding Shampoo is a daily, bond-rebuilding cleanser that strengthens weakened keratin, soothes dry or flaky scalps, and reduces breakage for visibly healthier hair.

This sulfate-free shampoo combines COSRX's patent-backed PEPTIDE-132 tripeptide complex with a gentle cleansing base to lift oil, product buildup, and impurities while supporting the structure of each hair strand. Designed for everyday use, it focuses on repairing internal bonds rather than only coating the surface, helping dry, damaged, or chemically treated hair feel stronger and look smoother over time.

How does this shampoo rebuild hair bonds?

The PEPTIDE-132 complex is formulated to interact with compromised keratin, helping to reconnect and reinforce weakened areas inside the hair fiber. Regular use supports reduced breakage and improved strand integrity without harsh surfactants or heavy silicones.

• Patented tripeptide targets broken keratin linkages at the cortex level.
• Lightweight formula that penetrates rather than masks damage.
• Sulfate-free cleansing preserves natural oils during repair.

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

Yes — the formulation includes soothing and moisturizing components to balance scalp condition while removing flakes and buildup. It helps reduce irritation tendencies by restoring a healthier scalp environment, which supports stronger hair growth over time.

• Gently removes dandruff-causing residue and excess oils.
• Moisture-supporting ingredients help relieve tightness and itchiness.
• Non-irritating surfactants suitable for sensitive scalps.

How should I incorporate this into my haircare routine for best results?

For optimal bond repair, use the PEPTIDE-132 Shampoo daily, pair it with the PEPTIDE-132 Hair Treatment two times weekly, and finish with the Hair Oil on damp hair to seal and smooth. Consistent layering of the trio strengthens strands, reduces split ends, and maintains manageability between styling.

• Daily: shampoo to cleanse and begin bond rebuilding.
• 2x/week: intensive hair treatment to target deeper damage.
• After-wash: apply hair oil on semi-damp lengths to reduce frizz and lock in shine.

Is this product safe for color-treated or chemically processed hair?

The gentle, bond-focused formula is formulated without SLS/SLES, parabens, phthalates, or animal-derived ingredients, making it suitable for many color- or treatment-maintained hairs. Because it works to rebuild internal keratin, it can complement professional services aimed at strengthening chemically altered strands.

• Free from harsh sulfates that strip color or weaken treated hair.
• Non-animal-derived actives and cruelty-free formulation.
• Supports structural repair without heavy residue buildup.

Who is this for: COSRX PEPTIDE 132 Hair Bonding Shampoo is tailored for anyone with dry, brittle, chemically treated, or frequently styled hair seeking a daily cleanser that actively repairs inner hair structure while calming a flaky or irritated scalp. It’s a good match for people who want salon-grade bond repair at home and prefer cleaner, gentler ingredients in their routine.
