COSRX PEPTIDE 132 Hair Care Kit — 3-Step Bond-Repair Shampoo, Treatment & Oil Serum for Damaged, Dry Hair

COSRX PEPTIDE 132 Hair Care Kit is a three-step bond-repair system — shampoo, deep treatment, and oil serum — formulated to strengthen damaged, dry hair and soothe irritated scalps.

This kit combines COSRX's patented PEPTIDE-132 complex with gentle cleansing and salon-grade conditioning to rebuild weakened keratin bonds, reduce breakage, and add lasting shine. The trio is designed to be used together for optimal results: a daily bonding shampoo to cleanse and fortify, a periodic treatment to repair and restore, and a lightweight oil serum to seal moisture and control frizz. All formulas avoid harsh sulfates and parabens, making the set suitable for sensitive scalps and regular use.

How should I use the three-step kit for best results?

Follow a simple routine: cleanse daily with the PEPTIDE-132 Shampoo, apply the Hair Treatment twice weekly as an intensive bond-rebuilding mask, and use the Hair Oil on damp or dry hair to lock in moisture and polish strands. Consistent layering of these steps enhances bond repair and long-term smoothness.

• Daily: massage shampoo into scalp, rinse thoroughly to remove buildup.
• Twice weekly: apply treatment mid-length to ends, leave per instructions, then rinse.
• Finishing: pump a small amount of oil onto semi-wet or dry hair to tame frizz and add shine.

What does the PEPTIDE-132 complex do for damaged hair?

PEPTIDE-132 is a tripeptide-based technology designed to target broken keratin bonds and reinforce hair structure. It acts at weak points in the fiber to reduce split ends and improve tensile strength without weighing hair down.

• Targets weakened keratin and broken bonds to reduce breakage.
• Helps rebuild elasticity and resilience in stressed fibers.
• Works in combination across the shampoo, treatment, and oil for cumulative effects.

Can this kit help sensitive or itchy scalps and dandruff-prone hair?

The Shampoo cleanses gently to remove dirt and buildup while avoiding strong sulfates, which can strip the scalp. Though not a medicated dandruff treatment, the formula is designed to calm and refresh irritated scalps and support healthier-looking hair when used regularly.

• Sulfate-free cleansing to reduce irritation risk for sensitive scalps.
• Removes residue that can exacerbate flakiness and discomfort.
• Follow with treatment and oil to restore moisture balance and reduce dryness.

How will the Hair Oil Serum affect styling and daily manageability?

The lightweight oil serum smooths cuticles, detangles strands, and provides a glazed, low-frizz finish that supports styling. A small amount delivers shine and slip without greasiness, helping hair hold styles more cleanly and resist flyaways throughout the day.

• One pump smooths and tames frizz for a polished look.
• Adds slip to ease combing and minimize breakage during styling.
• Seals moisture to prolong the effects of the treatment and reduce dryness.

Who is this for: COSRX PEPTIDE 132 Hair Care Kit is tailored for people with chemically treated, heat-styled, or physically stressed hair who want to repair bonds and improve manageability. It suits sensitive scalps and anyone seeking a clean-beauty, salon-quality repair routine they can use at home. If your priority is medicated scalp therapy for severe dandruff, consult a specialist; for structural repair, this kit is a targeted, everyday regimen to strengthen and smooth hair over time.
