How do I use the Kérastase Nutritive 8H Magic Night Serum?

Apply a small amount to dry or damp hair before bed, working it through mid-lengths and ends. Leave it in overnight and style as usual in the morning. No rinsing is needed.

Is it suitable for fine hair?

Yes. The water-based, lightweight milky-gel texture is designed for fine hair and is described as non-greasy, so it adds shine and softness without heavy buildup.

Can I use it on curly or wavy hair?

Yes. It is made for dry, wavy and curly textures and helps with detangling, frizz and shine. Apply to damp hair for easier distribution through curls.

Does it work on dry hair only?

It works on both dry and damp hair. Damp application spreads more evenly through lengths, while dry application is convenient for a quick overnight treatment.

What is in the formula?

The key ingredients are niacinamide and glycerin, with vitamins and protein. It is water-based, scented and made in France.

How does it compare with a regular leave-in conditioner?

It is a leave-in treatment with overnight results, so it is used before bed rather than as a daytime styler. Reviewers say it gives more shine and less damage than typical lightweight leave-ins, at a higher cost.
