How it works
A shampoo is the one hair step meant to be rinsed away, so what it leaves behind on the scalp is the whole question. This is the wash step in COSRX's PEPTIDE-132 range, worked into a lather in the hands first and then massaged into a scalp that is wet all the way through. The lather running down through the lengths is enough for them; the ends do not need to be scrubbed. It comes before the bonding treatment, which is the step that belongs on the mid-lengths and ends afterwards. Wash as often as you already do, because a bonding routine is a habit rather than a weekly rescue.

COSRX Peptide-132 Ultra Perfect Hair Bonding Shampoo
What is this shampoo actually for?
This is a low-sulfate shampoo built around a trio of tripeptides, tripeptide-1, tripeptide-2 and tripeptide-3, positioned mid-list alongside biotin, niacinamide and zinc PCA. The cleansing base runs on gentler surfactants like sodium C14-16 olefin sulfonate and cocamidopropyl betaine rather than a harsh sulfate, so it is aimed at washing hair that needs conditioning support, not stripping it. Niacinamide and zinc PCA sit toward the scalp-care side of the formula.
Is this shampoo suitable for a sensitive or oily scalp?
No mineral oil, silicone, paraben or added colourant appears on the ingredient list, and the surfactant system leans on milder cleansers rather than a classic sulfate. Zinc PCA and piroctone olamine, both associated with a fresher-feeling scalp, sit in the middle of the list. Anyone with a known sensitivity to fragrance should note that fragrance/parfum is present.
How long before I notice a difference from using this shampoo?
A shampoo rinses off within minutes, so the tripeptides, biotin and niacinamide on this list get brief contact time on each wash rather than a leave-on window. Consistent use across the wash cycle is what lets a bond-support routine show up in how hair feels, not a single application. Pair it with the matching treatment for the fuller effect the line is built around.
Can I follow this shampoo with a leave-in oil or serum?
Yes, this shampoo is a rinse-off cleansing step, so a leave-in oil or serum applied afterward is not layering onto anything left behind by the shampoo itself. The formula's own conditioning agents, polyquaternium-10 and polyquaternium-6, are meant to detangle through the wash, not to replace a separate leave-in step.
How do I confirm my bottle is the authentic Korean-market formula?
COSRX runs its own verification rather than relying on a reseller's word: find the batch number and expiration date printed on your actual bottle, then enter them on the verification page at cosrx.com. Reading those two numbers off your own packaging, rather than trusting a listing, is the whole point of the check. This EAN, 8809598457331, is the real barcode for this size.

How to use
- Use the PEPTIDE-132 Ultra Perfect Hair Bonding Shampoo in place of your usual shampoo, on hair wet all the way through.
- A palmful, worked into a lather in your hands first, then massaged into the scalp with fingertips rather than nails.
- Rinse thoroughly, then follow with your usual conditioner or treatment through the mid-lengths and ends.
- As often as you already wash. Do not pile it straight onto dry hair; a shampoo needs water in the hair to spread at all.
Worth knowing
- Fragrance is on the ingredient list.

We find biotin to be very helpful for hair disorders. It also makes nails thicker, and oral biotin is exceedingly safe.
