KÉRASTASE Nutritive 8H Magic Night Serum overnight treatment — Travel 1.01 fl oz, hydrates & boosts shine

KÉRASTASE Nutritive 8H Magic Night Serum is an overnight leave-in treatment that hydrates, detangles and boosts shine using niacinamide and plant-based proteins in just one sleep cycle.

This travel-size 1.01 fl oz serum is formulated to work overnight, replenishing moisture to dry hair fibers while reducing friction from pillows and improving manageability by morning. Lightweight and non-greasy, the serum is designed for application on dry or damp hair and delivers targeted nourishment without weighing strands down. Ideal for anyone who wants an efficient, salon-quality overnight routine, it blends active ingredients to support smoother, shinier hair after 8 hours.

How does the 8-hour overnight action improve dry hair by morning?

The formula combines niacinamide with plant-based proteins to penetrate the hair fiber and restore hydration during sleep. While you rest, it works to reduce friction and surface roughness so hair feels smoother and reflects more light. Results are cumulative with regular use but visible after a single night for many users.

• Niacinamide helps improve moisture distribution along the strand.
• Plant-based proteins support fiber strength and elasticity.
• Lightweight emollients reduce pillow friction and surface frizz.
• Designed to show noticeable shine, detangling, and softness within 8 hours.

How should I use this serum for best overnight results?

Apply 2–4 pumps depending on your hair thickness and length, and distribute evenly through dry or damp hair before bed. Focus on mid-lengths and ends where dryness and breakage are most common, then style or braid hair loosely if desired to reduce movement during sleep. No rinsing is required; wake up and style as usual.

• Use 2 pumps for short/fine hair, 3–4 pumps for medium to thick hair.
• Massage gently to ensure even coverage, concentrating on ends.
• Can be used nightly or as needed for intensive overnight treatment.
• Suitable for dry hair types seeking extra moisture and shine.

Will this serum weigh my hair down or leave a greasy residue?

The formula is engineered to be lightweight and absorb into the hair fiber rather than sit on the surface. When applied in recommended amounts, it adds moisture and slip without heaviness, helping hair look natural and bouncy by morning. Over-application can make any hair product feel heavier, so follow the suggested pump amounts for your hair type.

• Non-greasy texture formulated for overnight absorption.
• Recommended dosing prevents buildup and preserves natural movement.
• Perfect for those who prefer leave-in treatments with a lightweight finish.
• Travel-size packaging (1.01 fl oz) fits easily into a routine without excess product waste.

Can I use this serum with other treatments or heat styling?

The Nutritive 8H Magic Night Serum is compatible with most leave-in and rinse-out products; apply it before heavier creams or oils if layering. Because it’s designed for overnight use, avoid immediate heat styling right after application. In the morning, you can style with heat tools as usual—use a heat protectant if applying higher temperatures.

• Layer under heavier oils or masks when seeking extra nourishment.
• Not intended as a heat-protectant—add a dedicated product before heat styling.
• Works well as part of a multi-step routine: treatment at night, styling prep in the morning.
• Travel-friendly size for carrying alongside other treatments.

Who is this for: KÉRASTASE Nutritive 8H Magic Night Serum is for people with dry, fragile, or dull hair who want a simple overnight solution to improve hydration, detangling, and shine. It’s suitable for those who prefer leave-in formulations, travelers needing a compact treatment, and anyone wanting to wake up to smoother, more manageable hair without extra morning effort.
