COSRX PEPTIDE-132 Hair Bonding Treatment at a glance

What this treatment does

When hair is damaged by heat styling, bleaching or chemical treatments, the protein structure of each strand weakens — leading to breakage, roughness, split ends and frizz. This treatment is a deep conditioner designed to intensively smooth and condition damaged hair from the outside in.

The peptide and bonding complex works on the hair surface and outer cuticle layer, temporarily filling in gaps and smoothing the rough texture that damage creates. The result is hair that feels noticeably softer, stronger and more elastic after each use.

To be honest about expectations: this is a surface conditioning treatment. It dramatically improves how damaged hair looks and feels, and it helps prevent further breakage by strengthening the outer structure. It does not permanently rebuild broken internal bonds — that would require the hair to grow out. But as a weekly treatment, it keeps damaged hair in the best possible condition while it recovers.

How to use it

1. Shampoo as normal, then squeeze out excess water.
2. Apply generously to mid-lengths and ends — where damage is worst.
3. Leave on for five to ten minutes. For heavily damaged hair, use a shower cap to trap heat and increase absorption.
4. Rinse thoroughly with lukewarm or cool water.
5. Use once or twice a week — more often for very damaged hair, once a week for maintenance.

Complete the routine

After rinsing out this treatment, apply a few drops of the PEPTIDE-132 Hair Bonding Oil Serum to damp hair for daily smoothing and shine between treatment days.

Frequently asked questions

Is it a conditioner or a treatment?

It is a treatment — more intensive than a daily conditioner. Use it once or twice a week in place of your regular conditioner, not in addition to it.

Can I leave it on longer than ten minutes?

You can leave it on for up to fifteen to twenty minutes for extra conditioning. Beyond that, there is no additional benefit — the hair absorbs what it can in that time.

Will it weigh down fine hair?

It is conditioning, so fine hair should use a smaller amount and focus on the ends only. Rinse thoroughly. If your hair is fine but not damaged, you may not need this level of treatment.

How is it different from the Oil Serum?

This Treatment is a rinse-out deep conditioner for weekly intensive care. The Oil Serum is a daily leave-in finishing product. They complement each other — this repairs, the oil serum maintains.

Does it help with split ends?

It temporarily seals and smooths split ends, making them less visible. It does not permanently repair splits — the only real fix for split ends is trimming. But it keeps them from getting worse.

Can I use it on extensions or wigs?

Yes, as long as they are made of human hair. Apply and rinse as directed.

How long does 120ml last?

Used once a week on medium-length hair, 120ml typically lasts two to three months.
