Overnight serum for dry hair

Hair care that works while you sleep

A leave-in serum you apply before bed. Formulated with niacinamide and plant-based proteins, it nourishes, hydrates and detangles dry, frizzy hair overnight, and the lightweight formula absorbs quickly, so it won't leave hair greasy or transfer to your pillowcase.

Made for the night

Kérastase designed it to work over 8 hours: it absorbs within minutes of application, then keeps nourishing while you sleep, for softer, shinier, more manageable hair in the morning.

What is in the formula

Niacinamide, vitamin B3, strengthens the hair fiber and helps lock in nutrients. Plant-based proteins deliver amino acids to the cortex to help retain moisture, and glycerin boosts the formula's hydration.

Style while you rest

Braid it, twist it into a top knot or leave it down. Kérastase suggests two braids after applying, taken out in the morning, for soft waves without heat.

How to use

Two to four pumps before bed

Apply to dry or damp hair before bedtime. Dispense 2 to 4 pumps depending on length and thickness, spread evenly between your palms and work through mid-lengths to ends. Style it for the night and wake up without rinsing.

  • Use it nightly on very dry hair.
  • Use 2 to 3 times a week to maintain.
  • Wear hair up or down, as you like.
Is it suitable for all hair types?

Yes. Kérastase says it works on fine, medium and thick hair, and the lightweight formula absorbs quickly without leaving residue.

Will it make my hair greasy or mark my pillowcase?

No. The formula absorbs within minutes, so it won't transfer to pillows or leave hair greasy, even though it keeps working for 8 hours.

How often should I use it?

It is gentle enough for nightly use. Kérastase recommends every night for very dry hair and 2 to 3 times a week for maintenance.

Should I sleep with my hair up or down?

Whichever is more comfortable. Many people apply it and then braid or top-knot their hair for added styling; the serum works either way.

Can I use it on color-treated hair?

Yes. Kérastase says it is safe for color-treated and chemically processed hair.

Do I rinse it out in the morning?

No. It is a leave-in serum, so no rinsing is required. Style as usual in the morning.

What does it smell like?

The Nutritive floral scent: violet leaves and ylang ylang on top, wild rose, white jasmine and tonka bean at the heart, and sandalwood, cinnamon bark and white cedar at the base.

Can I return it once opened?

Opened hair care can't be resold, so it is returnable only if it arrived damaged or was the wrong item. Sealed and unopened, you have 30 days from delivery to start a return.
