COSRX PEPTIDE 132 Hair Bonding Oil Serum Travel Size 0.94 fl oz — Lightweight Keratin Repair, Frizz Control & Gloss

The COSRX PEPTIDE 132 Hair Bonding Oil Serum is a lightweight keratin-infused finishing oil that repairs weakened hair bonds, tames frizz, and adds glossy shine with a single pump.

This travel-size 0.94 fl oz serum brings COSRX's patented PEPTIDE-132 technology into an on-the-go formula designed for dry, damaged, color-treated, and frizz-prone hair. It combines a targeted tripeptide complex with nourishing plant oils to reinforce keratin structure and seal the hair surface without weighing strands down. The fast-absorbing texture makes it suitable for daily touch-ups, styling protection, and finishing during blow-drying or air-drying.

How does this oil repair split ends and broken hair bonds?

PEPTIDE-132 is a tripeptide complex formulated to interact with compromised keratin, helping to reconnect and strengthen weak points along the strand. Rather than masking damage, the peptide works at the bond level while argan and jojoba oils condition the cuticle to reduce future breakage. Regular use supports smoother surfaces that are less prone to snapping during brushing or styling.

• Tripeptide complex targets weakened keratin bonds
• Keratin-supporting ingredients reinforce strand integrity
• Oil blend smooths cuticles to prevent mechanical damage

Will this serum leave hair greasy or heavy?

The formula is lightweight and designed to absorb quickly, leaving a glossy finish without a greasy residue. Use a single pump on semi-wet hair to lock in moisture and tame flyaways; add a tiny amount to dry ends for extra shine. Because it’s non-greasy, it works well on fine to medium hair when used sparingly.

• Fast-absorbing texture for weightless shine
• One-pump dosing prevents over-application
• Suitable for touch-ups on dry hair and finishing on damp hair

How should I use the travel-size serum in my routine?

For best results, incorporate this oil as the final step after cleansing and conditioning. Apply to semi-wet hair to seal moisture and protect during styling, or smooth a small amount over dry ends to reduce frizz and boost gloss. It pairs especially well with other PEPTIDE-132 products to maximize bond repair benefits.

• After shampooing and conditioning, pump into palm and distribute through mid-lengths to ends
• Use twice weekly or daily for styling protection and shine
• Combine with PEPTIDE-132 Shampoo and Hair Treatment for a complete regimen

Is this product safe for color-treated or sensitive scalps?

The formula is free from SLS/SLES, parabens, phthalates, and animal-derived ingredients, making it a gentle option for many hair types, including color-treated strands. It’s formulated without harsh surfactants and not tested on animals. However, if you have scalp sensitivities, patch testing before regular use is recommended.

• Free of SLS/SLES, parabens, and phthalates
• Contains no animal-derived ingredients and not tested on animals
• Lightweight, non-irritating base suitable for sensitive scalp care
