How it works
Colored, heat-styled or over-washed hair loses the density strands used to have, and a rich conditioner alone only coats the surface. This 400 mL shampoo works tripeptide-132, biotin and caffeine into the cleansing step, using milder surfactants like sodium C14-16 olefin sulfonate rather than a harsh sulfate. Zinc PCA and piroctone olamine add scalp comfort, while five ceramide entries near the list's end support the lengths. Washing consistently across a bottle this size is what a bond-support routine relies on. Follow with the matching treatment.
Key benefits
- Tripeptide-132, the bond-minded peptide the line is named for, is on the list
- Biotin, caffeine and zinc PCA look after the scalp side
- Five ceramide entries and amino acids close out the formula
- A dense, conditioned lather that rinses without squeak

COSRX PEPTIDE-132 Ultra Perfect Hair Bonding Shampoo (Single / 400mL)
What is this larger shampoo bottle formulated to do?
This 400 mL shampoo is the same low-sulfate formula built around tripeptide-132, biotin, caffeine and zinc PCA, positioned mid-list alongside a five-ceramide tail near the end of the ingredient list. The cleansing base uses gentler surfactants like sodium C14-16 olefin sulfonate rather than a harsh sulfate, so the intent is conditioning support during the wash rather than a stripping clean.
Is this shampoo gentle enough for a sensitive scalp?
No mineral oil, silicone, paraben or added colourant appears on this list, and the formula pairs milder cleansers with zinc PCA and piroctone olamine, both associated with scalp comfort, positioned mid-list. Fragrance/parfum is present, which anyone with a known fragrance sensitivity should note before a full wash.
Does buying the larger size change how the shampoo performs over time?
The 400 mL size carries the identical formula as the smaller bottle, so the wash-by-wash behavior does not change, only the number of washes the bottle covers. A bond-support shampoo works through repeated use across the bottle rather than in a single wash, so the larger size simply extends that same routine further.
Should I follow this shampoo with the bonding treatment or the oil serum?
This shampoo is a rinse-off cleansing step, so both the bonding treatment and the oil serum are reasonable next steps rather than competing ones: the treatment rinses off on damp mid-lengths and ends, while the oil serum is a leave-in finishing step for damp or dry hair. Neither ingredient list conflicts with what this shampoo rinses away.
How do I verify this bottle is authentic Korean-market COSRX?
COSRX checks its own units directly: find the batch number and expiration date printed on this bottle and enter them on the verification page at cosrx.com, reading them off your own packaging rather than trusting a listing description. The EAN for this 400 mL size is 8800311121461.

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.
- Denatured alcohol is on the list, which some dry or reactive skin finds drying.
- Collagen here is not plant-derived, so this is not a vegan formula.
