COSRX Peptide-132 Ultra Perfect Hair Bonding Oil Serum 28ml

WHY WE CHOSE THIS

We tested 6 hair oil serums. Most left hair greasy or weighed down fine strands. COSRX's Peptide-132 Oil Serum is the only one that added visible shine and smoothness to our tester's damaged ends without any heaviness. From COSRX — the clinical K-Beauty brand trusted for ingredient-first formulas.

WHO IT'S FOR

• Dry, frizzy ends that won't smooth out
• Fine hair that goes flat with regular oils
• Anyone who wants shine without the grease

THE TEXTURE

An ultra-light, fast-absorbing oil that disappears into the hair shaft in seconds. No sticky residue. No greasy pillow. Just smooth, glossy strands.

HOW TO USE

On damp or dry hair, apply 1–2 drops to mid-lengths and ends. Avoid the roots. Style as usual. Use daily or as needed.

THE FULL INGREDIENT STORY

• Peptide-132 Complex (bond-strengthening peptide blend)
• Camellia Oil (lightweight shine + moisture seal)
• Argan Oil (frizz control + elasticity)
• No silicones. No artificial fragrance. No alcohol.
