COSRX PEPTIDE-132 Hair Strengthening Oil Serum - 28 ml

COSRX PEPTIDE-132 Hair Strengthening Oil Serum is a water-free oil-silicone serum for hair ends, built around Tripeptide-132 and seven plant oils. It smooths flyaways, tames frizz and adds shine without weighing hair down. One of the shortest formulas in its category - just 24 ingredients, with no water, no alcohol and no dyes.

About the product

COSRX is a Korean brand known for short, predictable ingredient lists, and this serum is a good example. It has 24 ingredients on the list and not a drop of water, so it needs no preservatives. The base is dimethicone, dimethiconol and light esters, responsible for the immediate smoothness and for the fact that the product does not feel sticky or heavy.

The brand markets this formula as a blend of seven plant oils, and all seven are indeed listed: argan, olive, Japanese camellia, jojoba, rice bran, grape seed and macadamia. To be fair, argan oil sits in ninth position, and the remaining six oils appear below the fragrance compound - much like the namesake Tripeptide-132, which closes the list. This is a typical build for a finishing serum and is not a flaw, since the smoothness here comes from the emollient base, but it is worth knowing how the product is put together.

Ingredients you will love

• Tripeptide-132 HCl - the brand's namesake peptide
• Dimethicone and dimethiconol - responsible for smoothness and shine
• Argan oil (Argania spinosa) - the most abundant plant oil in the formula
• Six more oils - olive, Japanese camellia, jojoba, rice bran, grape seed and macadamia
• Vitamin E (Tocopherol) - an antioxidant that protects the oils from turning rancid

Who it's for

For damaged, dull and frizzy hair, as well as thick, coarse hair that is hard to style. It works on damp hair before blow-drying and on dry hair as a finishing step. With no water, alcohol or dyes, it is one of the simpler formulas in its category - a good choice if you want to keep the ingredient count on your hair low.

How to use

1. Apply 1-2 pumps to your palms and warm between your fingers.
2. Distribute through damp or dry hair, focusing on the mid-lengths and ends.
3. Do not apply directly to the scalp. Do not rinse out.

Precautions

The fragrance compound contains five allergens: hexyl cinnamal, limonene, citronellol, linalool and benzyl benzoate. The product is intended for the lengths - do not apply it to the scalp.
