KÉRASTASE Nutritive 8H Magic Night Serum travel 1.01 fl oz — overnight leave-in for dry hair, smoothness & shine

KÉRASTASE Nutritive 8H Magic Night Serum is an overnight leave-in treatment that deeply nourishes dry hair, reduces friction while you sleep, and reveals smoother, shinier strands by morning.

This travel-size serum (1.01 fl oz) blends niacinamide with plant-based proteins to replenish moisture, detangle, and boost surface shine without heavy residue. Designed to be applied before bed on dry or damp hair, it works through natural overnight repair and friction protection so hair wakes up softer and easier to style. The lightweight formula aims to hydrate the hair fiber, strengthen strands and improve manageability across one full sleep cycle.

How quickly will I see results after using the overnight serum?

Visible improvements in smoothness and shine can appear after a single night, while ongoing use helps hair feel more hydrated and easier to comb. The formulation targets surface friction and fiber nourishment so you should notice less morning tangling and a silkier touch.

• Works overnight—results observed after one sleep cycle
• Reduces pillow friction to minimize knots and breakage
• Leaves a lightweight, non-greasy finish for easy styling in the morning

Can I use this on all hair types and how much should I apply?

The serum is formulated for dry hair but can benefit normal hair that needs extra hydration or protection during sleep. Apply 2–4 pumps depending on length and thickness; focus on mid-lengths and ends while avoiding the roots for lighter hair types.

• 2 pumps for short or fine hair
• 3–4 pumps for medium to long or thicker hair
• Suitable for color-treated and chemically processed hair when used as directed

What ingredients help protect hair overnight and how do they work?

Niacinamide and plant-based proteins are key actives in this serum: niacinamide helps condition the surface and improve manageability, while proteins support the hair fiber to reduce friction-related damage. The combination hydrates internally and smooths the outer cuticle to improve shine and reduce breakage during sleep.

• Niacinamide: conditions hair surface for improved softness
• Plant-based proteins: support fiber strength and resilience
• Lightweight emollients: create a protective layer against pillow friction

How do I incorporate this serum into my evening routine?

Use it as the final step on dry or slightly damp hair before bed—dispense the recommended amount, distribute evenly, and gently comb or run fingers through hair to spread the formula. No rinsing is required; style as usual in the morning for best results.

• Apply 2–4 pumps to mid-lengths and ends
• Comb through to distribute evenly and detangle
• Sleep on a silk or satin pillowcase for enhanced friction reduction

Who is this for: KÉRASTASE Nutritive 8H Magic Night Serum is ideal for people with dry, frizzy, or tangling-prone hair who want an easy overnight treatment to boost hydration and shine. It suits those who prefer a leave-in, low-effort solution to improve morning manageability—especially travelers, busy professionals, and anyone looking to protect hair from friction while they sleep. Avoid heavy application at the roots if you have very fine hair, and follow the suggested pump amounts to prevent buildup.
