COSRX PEPTIDE 132 Hair Bonding Repair Treatment - Deep Conditioner Hair Mask, 4.05 fl oz, Repairs Breakage & Restores Shine

COSRX PEPTIDE 132 Hair Bonding Repair Treatment is a salon-grade deep conditioner designed to rebuild weakened keratin bonds, hydrate brittle strands, and reduce breakage and split ends.

This concentrated hair mask uses COSRX's patented PEPTIDE-132 tripeptide complex plus collagen and hyaluronic acid to reinforce hair structure from within while delivering lasting moisture and shine. It’s formulated for all hair types and created to be used as a regular intensive step in a bond-repair routine—bringing professional-level keratin support into a simple at-home treatment.

How does this treatment repair damaged or broken hair fibers?

The PEPTIDE-132 complex is engineered to target compromised keratin and help reconnect weakened sites along the hair shaft. Rather than just coating the surface, the formula works to strengthen internal bonds and help prevent further breakage when used consistently.

• Tripeptide complex designed to interact with damaged keratin structures
• Collagen supports elasticity for reduced snap and brittleness
• Hyaluronic acid draws and locks in moisture for pliability

When and how often should I use this deep conditioner for best results?

Apply the treatment twice weekly or whenever hair feels particularly dry or stressed from styling and chemical services. For optimal outcomes, use as part of the COSRX PEPTIDE-132 Hair Bonding Trio: shampoo, treatment, and finishing oil.

• Use PEPTIDE-132 Shampoo to cleanse before treatment
• Leave the mask on treated hair for the suggested time per instructions
• Finish with PEPTIDE-132 Hair Oil on semi-wet hair to lock in results

Will this product work for different hair types and colored or chemically treated hair?

Yes—this formula is suitable for all hair types, including color-treated and chemically processed hair, because it focuses on rebuilding keratin bonds and restoring moisture without harsh sulfates or animal-derived ingredients. Its gentle, concentrated approach helps reinforce fragile strands regardless of texture or treatment history.

• Safe for color-treated and chemically processed hair
• Free from SLS/SLES, parabens, and phthalates for gentler care
• Non-animal-derived ingredients and cruelty-free testing

What sensory and practical benefits can I expect after using the treatment?

After a few applications, hair typically feels softer, smoother, and more manageable with improved elasticity and reduced frizz. The treatment aims to leave hair shinier and less prone to split ends, making styling easier and extending the life of blowouts and finished looks.

• Softer, silkier texture and visible shine
• Reduced frizz and easier detangling
• Stronger strands that resist breakage during styling

Who this is for: This deep-conditioning bond repair treatment is intended for anyone experiencing dryness, breakage, split ends, or loss of elasticity—especially people who regularly color, heat-style, or chemically treat their hair. It’s also a good match for anyone seeking a clean-beauty, salon-level repair step that integrates easily into a weekly hair-care routine.
