Peptide 132 Hair Bonding Repair TreatmentCOSRX Peptide 132 Hair Bonding Repair Treatment 240 ml (8.1 fl oz)

A twice-weekly bond-care step

This treatment is designed to be used twice a week after shampooing, giving dry, damaged hair a dedicated treatment step at home. Used regularly, it aims to leave hair feeling soft, smooth and silky, and the brand suggests reaching for it whenever hair feels dry or before styling.

How Peptide 132 is meant to work

The formula is built around Peptide 132, COSRX's patented tripeptide complex, which the brand says targets damaged keratin. It is described as fitting onto weakened keratin structures like a puzzle piece, reinforcing each strand and reducing the look of breakage and split ends.

Moisture for dry, brittle lengths

Collagen and hyaluronic acid are added to bring moisture and elasticity back to strands that feel dry and brittle. The manufacturer states the formula is free from SLS/SLES, parabens, phthalates and animal-derived ingredients, and is made without animal testing.

How to use

Cleanse hair and scalp with shampoo, then apply the treatment twice a week. For the full routine the brand pairs it with the Peptide 132 Hair Bonding Shampoo, finishing with the Peptide 132 Hair Oil Serum on towel-dried hair.
