COSRX Peptide 132 Ultra Perfect Hair Bonding Treatment

• Helps hair feel stronger and less brittle over time
• Improves smoothness + shine for a more polished finish
• Supports the look of reduced frizz and flyaways
• Adds slip for easier detangling and less breakage from brushing
• Great weekly “reset” for dry, processed, or heat-stressed hair

• Shampoo as usual and squeeze out excess water.

• Apply through mid-lengths to ends (focus on the most damaged areas).

• Leave on for 3–10 minutes depending on hair condition.

• Rinse thoroughly.

Pro tips:

• For fine hair: use a smaller amount and keep application mainly on the ends.

• For very dry/bleached hair: use 2–3x weekly until hair feels healthier, then maintain weekly.

• Avoid heavy application at the roots if you’re prone to oiliness.

• Chemically treated hair (bleach, colour, perms, straightening)
• Heat-styled hair that feels dry, rough, or prone to snapping
• Frizz-prone hair needing more smoothness and manageability
• Anyone wanting a bonding-style treatment that still feels lightweight

• Peptide 132 complex — supports the feel of stronger, more resilient hair and improves manageability
• Conditioning + slip agents — help detangle, soften, and reduce friction (less breakage from brushing)
• Smoothing support — helps reduce the look of frizz and improves shine
