How to choose a Kérastase hair oil or serum

Hair oils and serums do different jobs. A hair oil smooths the lengths and ends, adds shine and tames frizz. A serum treats one concern, often at the scalp or overnight while you sleep. Start with what your hair needs most.

Kérastase hair oils and serums by hair need

Where each one goes

Hair oils go on the mid-lengths and ends, on damp hair before styling or on dry hair to finish. Scalp serums go on the scalp and are left in. Night serums go through the lengths before bed. Whichever you choose, start with a small amount; fine hair needs less.

Kérastase Hair Oils & Serums FAQs

What is the difference between a hair oil and a hair serum?

A hair oil smooths and adds shine to the lengths and ends. A serum is a treatment for one concern, such as hair fall, dryness or split ends, and many are applied to the scalp or left in overnight.

Which Kérastase hair oil is best for my hair type?

Elixir Ultime suits all hair types. Choose Glaze Drops for long, frizz-prone hair, Huile Cicagloss for blonde hair, L'Huile Chroma Éclat for coloured hair and Huile Sublime Repair for curls.

Can I use Kérastase hair oil on fine hair?

Yes. Use a small amount, keep it to the mid-lengths and ends and avoid the roots so your hair stays light.

Can I use a hair oil and a serum together?

Yes. A scalp serum goes on the scalp and a hair oil on the lengths and ends, so they do different jobs. Apply the serum first.
