COSRX Peptide-132 Hair Bonding Repair Treatment, 8.11 fl oz — Deep Conditioner for Damaged Hair, Restores Strength & Shine

This rich hair mask blends COSRX’s patented PEPTIDE-132 tripeptide complex with collagen and hyaluronic acid to target broken bonds, split ends, and dryness. Designed for at-home use, the formula works as an intensive repair step in a weekly routine or as an emergency recovery treatment after chemical, heat, or mechanical damage. It’s free from SLS/SLES, parabens, phthalates, and animal-derived ingredients, making it a clean option for sensitive scalps and everyday haircare.

How does PEPTIDE-132 repair broken hair bonds?

The PEPTIDE-132 complex is engineered to interact with weakened keratin, helping to reconnect and reinforce hair structure rather than simply coating the strand. Regular use targets the points of breakage and split ends so hair becomes more resilient over time. Results are cumulative: the treatment repairs progressively with repeated applications.

• Tripeptide formula that adheres to damaged keratin for structural repair
• Collagen supports elasticity to reduce breakage under tension
• Hyaluronic acid restores internal moisture for improved strand flexibility
• Designed for repeated, weekly use for visible improvement

When and how should I use this deep conditioner?

Use the mask after shampooing on towel-dried hair, leaving it on for the recommended time to let peptides penetrate the cortex. For best results, incorporate it into a three-step PEPTIDE-132 routine: shampoo, treatment, then oil. You can apply the mask twice a week for damaged hair or once weekly for maintenance.

• Apply on clean, damp hair focusing on mid-lengths to ends
• Leave in according to instructions for intensive bond repair
• Rinse thoroughly and follow with PEPTIDE-132 Hair Oil for sealing and shine
• Use consistently—especially after chemical services or heat styling

Will this work on all hair types and textures?

Yes—formulated to benefit fine, medium, and coarse textures as well as chemically treated, curly, straight, and color-treated hair. The treatment restores moisture and structural integrity without heavy silicones or animal-derived agents, so it won’t leave fine hair feeling weighed down when used as directed. Curly and textured hair gain elasticity and reduced breakage; chemically treated hair can regain smoother, less-frayed ends.

• Safe for color-treated and chemically processed hair
• Light enough for fine hair when used sparingly; nourishing for thick hair
• Improves manageability for textured and curly hair types
• Free from SLS/SLES, parabens, and phthalates to suit sensitive scalps

What practical benefits can I expect after a few uses?

After several treatments, hair should feel softer, show fewer visible split ends, and handle mechanical stress (brushing, styling) better. Shine and slip improve as the mask hydrates the core of the hair fibers and reinforces bonds, making daily styling easier and less damaging. Effects build with consistent use as the product repairs progressively rather than masking damage temporarily.

• Reduced breakage and fewer split ends with repeated application
• Softer, smoother texture and improved comb-through ease
• Increased shine from restored moisture balance and sealed cuticles
• Hair feels stronger and more elastic under tension

Who is this for: COSRX PEPTIDE-132 Hair Bonding Repair Treatment is ideal for people with dry, brittle, chemically treated, or heat-damaged hair who want an at-home protocol that focuses on structural repair. It also fits those seeking a clean-beauty deep conditioner—suitable for sensitive scalps—and anyone wanting a weekly intensive mask to support longer, healthier-looking hair. Use it within a routine that includes a gentle cleanser and a sealing oil for the most consistent bond-repair results.
