COSRX PEPTIDE 132 Hair Bonding Repair Treatment Deep Conditioner, 4.05 fl oz — Repairs Breakage & Split Ends with Tripeptide, Coll

COSRX PEPTIDE 132 Hair Bonding Repair Treatment is an intensive deep conditioner that rebuilds weakened keratin bonds to reduce breakage, soften fibers, and restore moisture for visibly healthier hair.

This salon-level bonding treatment combines COSRX’s patented PEPTIDE-132 tripeptide complex with collagen and hyaluronic acid to target strands weakened by heat, chemical services, or environmental stress. The formula is designed to attach to compromised keratin structures and reinforce them, delivering hydration, elasticity, and improved manageability. Free from SLS/SLES, parabens, phthalates, and animal-derived ingredients, it fits a clean-beauty routine and works across hair types.

How does this treatment repair split ends and breakage?

The PEPTIDE-132 complex acts like a molecular connector that adheres to damaged keratin sites and helps rebuild the internal structure of the hair fiber. Regular use fills in weak points along the shaft, reducing the appearance and progression of splits while increasing tensile strength.

• Patented tripeptide formula targets and bonds to weakened keratin.
• Collagen supports elasticity to prevent future snapping.
• Hyaluronic acid delivers long-lasting hydration for flexible strands.
• Use twice weekly for noticeable reductions in breakage and split ends.

When and how should I use the COSRX PEPTIDE-132 treatment in my routine?

Apply after cleansing with a compatible shampoo; for best results, follow the full PEPTIDE-132 system. Work the mask through towel-dried hair, focusing on mid-lengths and ends, leave on for the recommended time, then rinse thoroughly.

• Use the PEPTIDE-132 Shampoo to prep the hair and remove buildup.
• Apply treatment twice a week or whenever hair feels dry and brittle.
• Finish with PEPTIDE-132 Hair Oil on semi-damp hair to lock in moisture.
• Can be used before styling to improve smoothness and manageability.

Will this product work for my hair type and scalp sensitivity?

The formula is designed for universal compatibility—safe for fine, thick, curly, chemically treated, or color-treated hair—because it focuses on rebuilding protein bonds and restoring hydration rather than coating hair with heavy silicones. It’s also formulated without common irritants, making it suitable for many sensitive scalps, though patch testing is recommended for those with severe sensitivities.

• Suitable for all hair textures and chemical histories.
• Free of SLS/SLES, parabens, and phthalates to reduce irritation risk.
• Non-animal derived ingredients and not tested on animals.
• Patch test if you have a reactive scalp or known allergies.

How quickly will I see results and what improvements can I expect?

Some users notice immediate changes in softness, shine, and manageability after the first application; measurable reductions in breakage and split ends typically appear with consistent use over several weeks. The treatment supports cumulative repair by strengthening bonds with repeated applications.

• Immediate: smoother texture, enhanced shine, reduced frizz.
• Short-term (2–4 weeks): improved elasticity and fewer breakages.
• Long-term: strengthened strands and less frequent need for trims.
• Best results when paired with the full PEPTIDE-132 hair system.

Who is this for: COSRX PEPTIDE 132 Hair Bonding Repair Treatment is made for anyone dealing with dryness, brittleness, heat or chemical damage, and visible split ends who wants a clean, science-forward deep conditioner. It suits shoppers seeking salon-grade results at home, people who prefer gentle, thoughtfully formulated products, and those building a targeted routine to rebuild hair health over time.
