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

COSRX PEPTIDE 132 Hair Bonding Oil Serum is a lightweight keratin-focused oil that repairs weakened bonds, tames frizz, and adds glossy shine to all hair types.

This travel-size 0.94 fl oz bottle delivers a concentrated finishing and reparative step for dry, damaged, or chemically treated hair. Built around COSRX’s patented PEPTIDE-132 tripeptide complex, the formula targets fragile keratin sites to fortify strands while argan and jojoba oils restore moisture without weighing hair down. Use it on damp hair to lock hydration or sparingly on dry ends to smooth flyaways and boost gloss.

How does the PEPTIDE-132 oil repair split ends and breakage?

The peptide blend is designed to associate with compromised keratin and reinforce weak points along the hair shaft. It doesn’t permanently fuse cuticles like a salon keratin service, but it strengthens strands and reduces the visual appearance of splits over time with regular use.

• Tripeptide complex targets and reinforces weak keratin bonds.
• Keratin-focused support reduces the look of split ends and breakage.
• Regular application improves strand resilience and manageability.

Will this oil weigh my hair down or leave a greasy residue?

The serum uses a lightweight, non-greasy carrier profile so it absorbs quickly and leaves a glossy finish rather than an oily film. A little goes a long way: apply 1–2 drops to damp hair or a touch to dry ends to avoid buildup.

• Fast-absorbing texture for shine without heaviness.
• Formulated with argan and jojoba oils for lightweight hydration.
• Best used sparingly on mid-lengths and ends to prevent weighing hair down.

How should I include this serum in my hair routine for best results?

For optimal bond-support benefits, use the COSRX PEPTIDE-132 range as a three-step system: shampoo, treatment mask, and finishing oil. The oil is most effective when applied to slightly damp hair after rinsing treatments to seal moisture and smooth the cuticle.

• Use COSRX PEPTIDE-132 Shampoo to cleanse and prepare strands.
• Apply the Hair Treatment mask twice weekly for concentrated bond repair.
• Finish with the Hair Bonding Oil Serum on semi-wet hair to lock in hydration and shine.

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 suitable for many color-treated and sensitive scalps. It’s formulated without animal testing and aims to provide conditioning benefits without harsh surfactants or common irritants.

• Free from SLS/SLES, parabens, and phthalates.
• No animal-derived ingredients; cruelty-free formulation.
• Suitable for routine use on color-treated hair when used as directed.

Who is this for: The COSRX PEPTIDE 132 Hair Bonding Oil Serum travel size is ideal for anyone wanting a compact, effective finishing oil that supports damaged or dry hair. It’s particularly useful for travelers, those trying the PEPTIDE-132 system for the first time, and people with chemically treated, heat-exposed, or frizzy hair who need lightweight bond support and instant gloss. Suitable for all hair textures when used in small amounts to target ends and unruly flyaways.
