K18 Molecular Repair Hair Oil 30ml

A finishing oil with the brand's peptide in it, so it does the usual oil jobs — smoothing frizz, adding shine — while also working on the strand itself. It is dry rather than greasy and highly concentrated, which is why the dose is counted in drops.

The actives

• K18PEPTIDE (sh-oligopeptide-78) — the patented peptide, formulated to work inside the strand rather than sit on it.
• Squalane — a lightweight emollient that smooths without the heaviness of a traditional oil.
• Avocado and sunflower oils — nourishing oils that soften the mid-lengths and ends.
• Vitamin E (tocopherol) — an antioxidant that helps keep the oil blend stable.

How to use it

One to three drops. On damp, towel-dried hair before styling, worked from mid-lengths to ends — wait four minutes before styling to get the most from the peptide. On dry hair, use sparingly as a finisher to smooth frizz and add shine. If you also use the Leave-In Molecular Repair Mask, apply the mask first, wait four minutes, then the oil, then four minutes more.

Who it's for

All hair types, fine hair included — start at a single drop on the ends. Overdo any oil and it looks greasy, and this one is concentrated enough that the temptation is to overdo it.
