The K18 Molecular Repair Hair Oil is a lightweight, silicone-free oil that helps strengthen hair, repair damage, and control frizz without weighing hair down.

Formulated with K18PEPTIDE™, it works both at the core of the hair fiber to target frizz-causing damage, and on the surface to smooth, add shine, and protect hair from heat up to 232°C.

It is suitable for all hair types, including curly, coily, and kinky hair, especially when sensitized by color, bleach, chemical services, or heat styling tools.

K18's Molecular Repair Hair Oil is not your typical hair oil.

Its biotechnological formula combines the K18PEPTIDE™with oils and smoothing agents such as avocado oil, sunflower oil, squalane, and hemisqualane. It helps to improve the hair fiber from within while immediately smoothing visible frizz on the surface.

Used on damp hair, it helps strengthen hair and control frizz during natural drying or styling. Used on dry hair, it provides a smoother, shinier, and more polished finish.

Its highly concentrated texture means only a few drops are needed, making it suitable even for fine hair or hair that is easily weighed down.
Usage tips
  • Apply to damp, towel-dried hair before styling.
  • Dispense 1 to 3 drops into hands, then distribute from mid-lengths to ends.
  • To fully benefit from K18PEPTIDE™'s strengthening properties, wait 4 minutes before styling.

On dry hair, apply 1 to 3 drops as a finishing touch to smooth frizz, tame flyaways, and add shine.

If you are also using the K18 Molecular Repair Hair Mask, first apply the mask to clean, damp hair, wait 4 minutes, then apply the oil and wait another 4 minutes to maximize the strengthening benefits.

Additional tips:

  • The formula is highly concentrated: always start with a small amount.
  • For fine hair, a single drop may be enough.
  • For thick, dense, curly or coily hair, apply in sections to better distribute the product.

Why choose K18 • Huile Capillaire Réparatrice Moléculaire ?

Repairs and strengthens the hair fiber

With K18PEPTIDE™, this oil helps target internal damage that makes hair more fragile and prone to frizz.

It supports the repair of hair sensitized by color, bleaching, heat, or chemical services.

24-hour frizz control

The formula works on two levels: deep down on damage, and on the surface to smooth the cuticle.

It helps reduce frizz and flyaways without a greasy or heavy finish.

Adds shine and a polished finish

A few drops are enough to give lengths a smoother, shinier, and neater appearance.

It's ideal as a finishing touch, especially for dry ends, dull hair, or curls lacking visual definition.

Protects against heat up to 232°C

Molecular Repair Hair Oil offers heat protection up to 232°C.

It can therefore be used before blow-drying, diffusing, or heat styling, while helping to limit damage responsible for frizz.
