Cosrx Peptide 132 Ultra Perfect Hair Bonding Oil Serum 28ml

Repair weakened strands and restore elasticity with a targeted leave‑in serum built around COSRX’s patented peptide‑132 complex.

Instead of masking damage with temporary coatings, this formula reinforces the hair’s internal structure. The peptide‑132 active ingredient supports keratin bonding while actively recharging depleted protein chains, which makes it particularly effective for color‑treated, chemically relaxed, or frequently heat‑styled hair. A foundation of vitamin E and seven extracted botanical oils delivers moisture directly to the cuticle line, sealing gaps without leaving a greasy film or flattening natural volume.

The highly concentrated liquid absorbs within seconds of application, creating a protective layer that resists humidity and daily styling friction. Each 28 ml bottle yields roughly 40 to 60 precise applications when dosed to mid‑lengths and ends. You can press two drops onto damp hair ahead of blow‑drying to reduce breakage, or sweep three to four drops over fully dry sections to smooth split ends and restore a polished luminosity. The blend finishes with a clean citrus‑woody aroma layered with crisp bamboo and green undertones.
