A leave-in night serum that nourishes dry hair while you sleep
Kérastase Nutritive 8H Magic Night Serum is an overnight leave-in treatment for dry hair. It works for eight hours while you sleep, with plant-based proteins from wheat, corn and soy that bring nourishment to the fiber and niacinamide, which helps lock that nutrition in and strengthen the hair's surface. Glycerin adds hydration, and anti-dryness polymers give immediate softness and limit friction against the pillow. In the morning, hair feels soft, supple and easy to style, and Kérastase reports hair up to 98% stronger in instrumental tests.
How it works
A light, milky serum that you pump onto dry or towel-dried lengths before bed. It melts into the hair without weighing it down or leaving a greasy trace on the pillow, and there is nothing to rinse out the next morning. It carries the signature Nutritive fragrance.
Who it suits
- Dry, rough or dull lengths and ends
- Fine to medium hair that gets weighed down by oils
- Hair that tangles or frizzes overnight
- Anyone who wants an easy treatment with no rinsing
Worth knowing before you buy: it contains silicones and fragrance, and it is designed for the lengths, not the scalp. Very thick or curly hair may need a richer mask from the same range as well.
How long one bottle lasts
With 2 to 4 pumps two or three nights a week, the 90ml bottle usually lasts around three to four months.
