COSRX Peptide-132 Hair Bonding Repair Treatment Deep Conditioner Mask, 4.05 fl oz — Repairs Breakage & Restores Softness

COSRX PEPTIDE-132 Hair Bonding Repair Treatment is a salon-grade deep conditioner that rebuilds weakened keratin bonds to restore softness, reduce breakage, and improve manageability.

This intensive hair mask blends COSRX’s patented PEPTIDE-132 complex with collagen and hyaluronic acid to target damaged, dry, or brittle strands. Designed to work as a repair step in a routine or as a weekly deep treatment, it focuses on reconstructing hair structure and locking in moisture without sulfates, parabens, phthalates, or animal-derived ingredients.

How does this treatment actually repair broken hair bonds?

The formula uses a tripeptide complex (PEPTIDE-132) that adheres to weakened keratin sites and reinforces them, helping strands resist breakage and split ends. Collagen and hyaluronic acid support moisture retention and elasticity so repair lasts beyond the first rinse.

• PEPTIDE-132 targets damaged keratin to rebuild internal bonds.
• Collagen adds pliability and strand support.
• Hyaluronic acid boosts hydration to reduce brittleness.

When and how should I use the COSRX PEPTIDE-132 mask for best results?

Use the treatment after shampooing: apply from mid-lengths to ends, leave on for the recommended time, then rinse. For visible improvement, incorporate it twice weekly and combine with the PEPTIDE-132 shampoo and oil in the same line for a coordinated bond-repair routine.

• After cleansing, apply to towel-dried hair focusing on damaged areas.
• Leave in according to directions (typically several minutes) then rinse.
• Use twice weekly, or more often on very damaged hair; finish with the matching hair oil for sealing.

Will this work for my hair type and common damage concerns?

The treatment is formulated to be effective for all hair types—straight, curly, wavy, and chemically treated—because it repairs keratin rather than changing hair texture. It targets common problems such as dryness, brittleness, split ends, and breakage caused by heat styling, coloring, or daily wear.

• Safe for color-treated and heat-styled hair when used as directed.
• Helps minimize split ends and reduce mechanical breakage.
• Suitable for fine to coarse hair because the action is bond-focused, not weighty conditioning.

Is the product clean and safe for sensitive scalps?

COSRX formulated this hair bonding treatment without SLS/SLES, parabens, phthalates, or animal-derived ingredients and did not test on animals. Because it concentrates on strand repair rather than harsh surfactants, it is generally gentle on sensitive scalps when used as a rinse-out mask.

• Free from SLS/SLES, parabens, and phthalates.
• Vegan-friendly formulation and cruelty-free practices.
• Recommended as a rinse-out treatment to avoid prolonged scalp contact if very sensitive.

Who is this for: COSRX PEPTIDE-132 Hair Bonding Repair Treatment is ideal for anyone with dry, damaged, chemically treated, or frequently styled hair who wants a targeted bond-repair step. It suits customers seeking salon-quality keratin repair at home, those wanting a clean-beauty option, and people who prefer a focused weekly mask to strengthen and hydrate hair without heavy buildup.
