How it works
Damaged or color-treated hair often feels rough because the surface layer has lifted, and a standalone oil only masks that without reaching the mid-shaft. This treatment pairs tripeptide-132 with argan, olive, camellia, jojoba and rice bran oils, worked through damp mid-lengths and ends after shampooing. Dimethicone and amodimethicone add slip and a sealed-feeling surface once rinsed. Soluble collagen and oat peptide add conditioning without the weight of a leave-in oil. Leave it in briefly, then rinse well.
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
- Five ceramide entries and amino acids close out the formula
- Soluble collagen and oat peptide condition without weighing hair down

COSRX PEPTIDE-132 Ultra Perfect Hair Bonding Treatment (Single / 240mL)
What is this hair treatment for?
This is a rinse-off conditioning treatment built around tripeptide-132, positioned mid-list after a base of glycerin, dimethicone and cetyl ethylhexanoate. Argan, olive, camellia, jojoba and rice bran oils sit further down the list alongside grape seed oil, giving the formula a gloss-focused oil blend on top of the peptide. It is meant for mid-lengths and ends rather than the scalp.
Is this treatment too heavy for fine or oily-scalp hair?
The formula is silicone-forward, dimethicone appears third and amodimethicone further down, which is what gives it slip and shine, so fine hair may want it kept to the ends rather than the roots. No mineral oil, paraben or added colourant appears on the list. Applying it only to damp mid-lengths and ends, as directed, keeps the richness away from the scalp.
Does the effect build with repeated use or is it a one-time fix?
A rinse-off treatment leaves behind whatever the oils, silicones and tripeptide-132 can deposit in the few minutes it sits on hair, so each wash reinforces the last rather than resetting from zero. Cumulative use across the bottle is what a bonding routine is built around, not a single application after damaged hair. Pairing it with the matching shampoo each wash keeps that build-up consistent.
Can I use this with a leave-in oil serum afterward?
Yes, this treatment rinses off before hair dries, so a separate leave-in oil serum applied to towel-dried or dry hair afterward is not competing with anything left behind. The treatment's own oil blend, argan, olive, camellia and jojoba among them, is designed to rinse mostly clear rather than sit on the surface like a leave-in would.
How can I tell this tube is the real Korean-market formula?
COSRX verifies its own units rather than leaving that to a seller: locate the batch number and expiration date printed on the tube itself, then check them against the verification page on cosrx.com. Reading those numbers off your own packaging is deliberate, not a formality. The barcode on this size is 8800311121478.

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.
