How it works
A hair oil is a finishing step, which means it goes on after the wash and after the towel rather than into either. This is the oil serum in COSRX's PEPTIDE-132 range, thin enough to work through the lengths without flattening them. A few drops warmed between the palms and drawn from the mid-lengths to the ends is the whole application, and the roots are left out of it on purpose. Ends that look dull and rough once the hair has dried are what a finishing step is for, and another wash only resets the day. It can go on damp hair before drying, on dry hair afterwards, or a little of both.
Key benefits
- Tripeptide-132, the bond-minded peptide the line is named for, closes the list
- Argan, olive, camellia, jojoba, rice bran and grape seed oils build the gloss
- A dry-oil slip that leaves shine without residue
- Seals ends after heat styling or air drying

COSRX Peptide-132 Ultra Perfect Hair Bonding Oil Serum
What is this hair oil serum for?
This is a lightweight dry-oil serum led by dimethicone and a blend of silicone derivatives, with argan, olive, camellia, jojoba and rice bran oils listed further down and tripeptide-132 closing out the list. It is built to seal and add shine to dry ends after washing or heat styling rather than to clean or condition through a wash cycle.
Will this weigh down fine hair or leave it greasy?
The formula opens with dimethicone and other silicone-family ingredients rather than a heavy mineral oil or butter, which is what gives it a dry-oil feel that sits on the surface rather than soaking in heavily. No mineral oil, paraben or added colourant appears on the list. Warming a small amount between palms and keeping it away from the roots, as directed, helps fine hair avoid a greasy look.
Does the shine effect build over repeated use?
A leave-in oil serum stays on hair rather than rinsing out, so each application adds its own layer of gloss rather than accumulating chemically over time the way a rinse-off treatment might. Using it consistently on damp or dry ends after styling is what keeps the look consistent wash to wash, not a change in the formula's effect itself.
Can I use this after the shampoo and treatment from the same line?
Yes, this serum is designed as the leave-in final step after the rinse-off shampoo and treatment, applied to damp or dry hair rather than during the wash. Because the shampoo and treatment rinse off before this step, there is nothing left behind for the serum's oils to conflict with.
How can I confirm this bottle is the real Korean-market formula?
COSRX verifies units itself rather than through a reseller: locate the batch number and expiration date printed on your bottle and enter them on the verification page at cosrx.com. Reading those figures off your own packaging is the point of the exercise. The barcode for this size is 8809598457355.

Ingredient list read from jolse.com on 9 September 2026.
21 of 24 explained
- Dimethicone silicone
- Dimethicone is the most used cosmetic silicone. It forms a breathable film that smooths the surface, slows water leaving skin, and gives the slip that makes a primer or cream feel silky. It is inert and does not penetrate.
- Hydrogenated Poly(C6-14 Olefin) emollient
- Hydrogenated Poly(C6-14 Olefin) is a synthetic hydrocarbon emollient. It gives a smooth, silicone-like glide and is completely stable, so it does not go rancid.
- Cetyl Ethylhexanoate emollient
- Cetyl Ethylhexanoate is a synthetic ester used as a dry-feeling emollient. It spreads easily, leaves a silky rather than oily finish, and helps disperse pigments and UV filters evenly.
- Dicaprylyl Carbonate emollient
- Dicaprylyl Carbonate is a light, fast-spreading emollient with a notably dry finish. It is chosen where a formula has to spread thin without leaving a heavy film.
- Dimethiconol silicone
- Dimethiconol is a high-molecular-weight silicone that leaves a longer-lasting smooth film than dimethicone. It is used for lasting slip and shine.
- Dicaprylyl Ether emollient
- Dicaprylyl Ether is a very light emollient used to make a formula spread quickly and feel dry rather than oily.
- Argania Spinosa Kernel Oil emollient
- Argan Oil is pressed from the argan kernel and is rich in oleic and linoleic acids plus vitamin E. It is a medium-weight emollient that absorbs reasonably fast.
- Fragrance/Parfum fragrance
- Fragrance, or Parfum, is a single declaration standing for a whole scent blend, which can be dozens of materials. Regulators allow it as a trade secret, so a list showing only this word does not say what the scent is made of. It is the most common trigger named by people with reactive skin.
- Hexyl Cinnamal fragrance component
- Hexyl Cinnamal is a jasmine-like aromatic. It is one of the 26 fragrance components EU labelling requires to be named individually.
- Limonene fragrance component
- Limonene is the citrus-peel aromatic. It appears here because EU labelling requires 26 fragrance components to be named individually rather than hidden inside "fragrance", and it is one of them.
- Citronellol fragrance component
- Citronellol is a rose-geranium aromatic and one of the 26 fragrance components EU labelling names individually.
- Tocopherol antioxidant
- Tocopherol is vitamin E. It is an oil-soluble antioxidant that protects the oils in a formula from going rancid and works on skin as an emollient, and it is regularly paired with vitamin C because each keeps the other going for longer.
9 more explained
- Linalool fragrance component
- Linalool is a floral aromatic found in lavender, bergamot and coriander. It is one of the 26 fragrance components EU labelling requires to be declared by name.
- Benzyl Benzoate fragrance component
- Benzyl Benzoate is a faintly balsamic aromatic that also acts as a fixative, holding a fragrance on skin longer. It is one of the 26 declarable fragrance components.
- Olea Europaea (Olive) Fruit Oil emollient
- Olive Fruit Oil is high in oleic acid and plant sterols. It is a rich emollient that suits dry skin and is heavy enough that blemish-prone skin often does not get on with it.
- Camellia Japonica Seed Oil emollient
- Camellia Seed Oil is the traditional Korean and Japanese hair and skin oil, high in oleic acid. It is a light emollient that absorbs quickly for its richness.
- Simmondsia Chinensis (Jojoba) Seed Oil emollient
- Jojoba Oil is a liquid wax rather than a true oil, and its structure is close to human sebum, which is why it absorbs so readily. It is an emollient that leaves a soft, non-greasy finish.
- Oryza Sativa (Rice) Bran Oil emollient
- Rice Bran Oil is pressed from the bran left over from milling rice. It carries vitamin E and a group of rice-specific antioxidants, and it is a light emollient.
- Vitis Vinifera (Grape) Seed Oil emollient
- Grape Seed Oil is a light, linoleic-acid-rich oil with a fast, dry absorption. It is one of the plant oils used where an oil is wanted without a heavy finish.
- Macadamia Ternifolia Seed Oil emollient
- Macadamia Seed Oil is unusually high in palmitoleic acid, a fatty acid that human sebum also contains, which is why it absorbs faster than most nut oils. It is a cushioning emollient for dry skin.
- Tripeptide-132 HCl peptide
- Tripeptide-132 HCl is a three-amino-acid peptide supplied as a hydrochloride salt, which is simply the form that dissolves readily in water.

How to use
- Use the Hair Bonding Oil Serum after washing, on hair towelled to damp, or on dry hair as a finish.
- Two or three drops warmed between the palms, then drawn from the mid-lengths down to the ends.
- It goes on after any rinse-out treatment and before heat styling, once the towel has taken the drips out.
- Whenever the ends look rough. Do not work it into the roots or the scalp; an oil there flattens hair rather than smoothing it.
Worth knowing
- Fragrance is on the ingredient list.
- An essential oil or citrus peel oil is on the list; those carrying a fragrance sensitivity should check it.
