How it works
A rinse-out treatment gets a few minutes on the hair and nothing more, so where it goes matters as much as how long it stays. This is the treatment step in COSRX's PEPTIDE-132 range, spread through the mid-lengths and ends on hair towelled to damp rather than dripping. Water left in the hair is what stops a thick cream sitting in one place, and the scalp is left out of it on purpose. It follows the shampoo and comes before any leave-in or oil, once or twice a week rather than at every wash. Hair that feels rough from heat or color is the case a treatment step answers.
Key benefits
- Tripeptide-132, the bond-minded peptide the line is named for, is on the list
- Argan, olive, camellia, jojoba, rice bran and grape seed oils carry the gloss
- Oat peptide, soluble collagen and amino acids condition the lengths
- Rinses to silky, detangled hair without buildup

COSRX Peptide-132 Ultra Perfect Hair Bonding Treatment
What is this hair bonding treatment for?
This is a rich rinse-off conditioning cream built around tripeptide-132, listed among a run of six plant oils, argan, olive, camellia, jojoba, rice bran and grape seed, further down the ingredient list. Oat peptide and soluble collagen follow shortly after, adding a conditioning layer on top of the oil blend. It is meant to condition mid-lengths and ends rather than clean the scalp.
Will this feel too heavy for fine hair?
The base leans on dimethicone, cetyl alcohol and stearyl alcohol for slip and richness, so fine or easily weighed-down hair may prefer keeping it to the ends. No mineral oil, paraben or added colourant appears on the list. Applying it as directed, to damp mid-lengths and ends rather than the roots, is the way to manage that richness.
Does this treatment need repeated use to work, or is one application enough?
A rinse-off cream leaves behind only what the oils, silicones and tripeptide-132 deposit in the few minutes it sits on hair, so each wash builds on the last rather than resetting. Consistent use through the bottle, paired with the matching shampoo, is how a bond-support routine is meant to show up over time rather than after a single wash.
Can this be layered with a leave-in oil serum?
Yes, since this treatment rinses out before hair dries, a leave-in oil serum applied afterward to damp or dry hair is not competing with anything left behind by the rinse step. The treatment's own oils, argan and camellia among them, are formulated to mostly rinse away rather than remain on the surface.
How do I check this tube is genuinely Korean-market COSRX?
COSRX handles its own authentication: find the batch code and expiration date printed on your tube, then enter them on the verification page at cosrx.com rather than taking a seller's description at face value. That is the deliberate design of the check. The EAN for this size is 8809598457348.

How to use
- Use the PEPTIDE-132 Ultra Perfect Hair Bonding Treatment after shampooing, on hair towelled to damp rather than dripping.
- A generous amount through the mid-lengths and ends, kept off the scalp itself.
- Shampoo first, this second. Leave it for the time the pack gives, then rinse.
- Once or twice a week. Do not work it into the roots; a treatment weighs down the one part of the hair that does not need it.
Worth knowing
- Fragrance is on the ingredient list.
- This formula carries an active acid, so pairing it with another exfoliant in the same routine is worth spacing out.
- Collagen here is not plant-derived, so this is not a vegan formula.
