COSRX PEPTIDE 132 Hair Bonding Repair Treatment Deep Conditioner Mask — 8.11 fl oz, Repairs Breakage & Hydrates

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

If your hair feels brittle, has split ends, or looks dull from chemical processing or heat styling, this concentrated treatment is formulated to strengthen strands and add lasting hydration. The formula centers on COSRX's proprietary PEPTIDE-132 tripeptide complex alongside collagen and hyaluronic acid to target the internal keratin structure while improving surface smoothness. It’s designed for at-home use as part of a weekly routine or whenever strands need intensive repair and shine.

How does this treatment rebuild damaged hair bonds?

The PEPTIDE-132 complex works like a binding agent that complements weakened keratin chains, helping to reconnect and fortify strands from the inside out. Regular use supports reduced breakage and improved elasticity without weighing hair down.

• Tripeptide PEPTIDE-132 targets and reinforces compromised keratin fibers.
• Collagen boosts internal strength and resilience for brittle sections.
• Hyaluronic acid delivers moisture to restore flexibility and reduce snapping.

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

Use the mask after shampooing two to three times weekly or as needed on especially damaged hair. Leave on for several minutes to allow the active ingredients to penetrate, then rinse thoroughly; pair with the matching shampoo and oil for a comprehensive repair routine.

• Apply to clean, towel-dried hair focusing on mid-lengths and ends.
• Leave in according to label directions for deeper bond repair.
• Follow with PEPTIDE-132 Hair Oil on semi-damp hair to seal and add shine.

Will this product work on all hair types and textures?

The formula is designed to be compatible with a wide range of hair types—fine, thick, curly, or chemically treated—because it targets structural keratin rather than just surface coating. It’s lightweight enough for many users yet concentrated enough to benefit very dry or chemically damaged hair.

• Suitable for color-treated, heat-styled, or chemically processed hair.
• Balances moisture without leaving a heavy residue on finer strands.
• Helps strengthen textured and curly hair prone to breakage.

Is this treatment formulated with clean-beauty standards?

COSRX PEPTIDE 132 Hair Bonding Repair Treatment is made without SLS/SLES, parabens, phthalates, or animal-derived ingredients and is not tested on animals. The formulation focuses on effective, conscious ingredients for everyday hair care.

• Free of common sulfates and parabens to reduce irritation risk.
• Vegan-friendly and cruelty-free; no animal testing.
• Concentrated actives promote repair rather than temporary gloss alone.

Who is this for: This treatment is ideal for anyone with dry, brittle, or chemically treated hair seeking a targeted repair mask that strengthens from within. It fits into weekly maintenance routines for users who want salon-level keratin support at home, and is a good match for those avoiding harsh sulfates and animal-derived ingredients. If you frequently heat style, color, or notice split ends and snap-prone lengths, incorporating this product into your regimen can help restore resilience and shine over time.
