Note:

• What is Kérastase Nutritive 8HR Magic Night Hair Serum?

  Kérastase Nutritive 8HR Magic Night Hair Serum is an intensive, luxury overnight leave-in dry hair treatment designed to deeply restore, plump, and hydrate parched, dehydrated strands while you rest. Utilizing plant-based proteins, Iris Root extract, niacinamide, and a blend of five essential vitamins, it works like a rich night cream for your face to rejuvenate strands over an eight-hour window.

• Do you need to wash Kérastase Nutritive 8HR Magic Night Hair Serum out in the morning?

  Not at all. Your strands completely absorb Kérastase Nutritive 8HR Magic Night Hair Serum over an eight-hour period, meaning your hair will feel soft, clean, and entirely product-free when you wake up. There is absolutely no sticky residue or heavy buildup left behind, so you can go straight into using your regular morning styling tools without a morning wash.

• How do I use Kérastase Nutritive 8HR Magic Night Hair Serum before bedtime?

  Right before you go to sleep, distribute two to four pumps of Kérastase Nutritive 8HR Magic Night Hair Serum into your hands, depending on your length and texture. Work the lightweight cream evenly through the mid-lengths and ends of dry or damp hair. For loose waves or defined curls, you can braid your strands or twist them into a soft bun after application. There is no need to rinse in the morning.

• Will Kérastase Nutritive 8HR Magic Night Hair Serum make my fine hair look flat or greasy?

  No, Kérastase Nutritive 8HR Magic Night Hair Serum is specifically designed to offer completely weightless moisture. While it is rich in hair-softening conditioning vitamins and plant-based proteins, the texture is featherlight and leaves no oily film behind. If you have fine hair that thins or flattens easily, simply start with a single pump applied strictly to your absolute ends.

• Will Kérastase Nutritive 8HR Magic Night Hair Serum leave stains on my pillowcase?

  Not a bit. This rapid-absorbing fluid features anti-dryness polymers that melt completely into the hair fiber within a couple of minutes. Because Kérastase Nutritive 8HR Magic Night Hair Serum sinks in so quickly, all the deep hydration stays locked inside your strands to protect against pillow friction rather than transferring onto your bedding.

• Can I use Kérastase Nutritive 8HR Magic Night Hair Serum on colour-treated or bleached hair?

  Yes, Kérastase Nutritive 8HR Magic Night Hair Serum is entirely safe and highly recommended for highlighted, bleached, or chemically processed hair. Intense salon lifting services can leave the hair cuticle chapped and severely dehydrated. This serum helps replenish those lost proteins and lipids, building excellent structural elasticity without shifting or affecting your hair colour.

• What specific benefits does Kérastase Nutritive 8HR Magic Night Hair Serum provide?

  Kérastase Nutritive 8HR Magic Night Hair Serum provides deep 8-hour nourishment, shields your strands against harsh pillowcase friction, aids in detangling, and actively eliminates stubborn morning frizz. Consumer tests reveal that 94% of users felt their hair was significantly shinier, softer, and completely revitalized by morning after just a single night of use.

• What hair types is Kérastase Nutritive 8HR Magic Night Hair Serum suitable for?

  The formula is professionally optimized to treat all dry hair types, including fine, medium, coarse, curly, straight, coily, and wavy hair structures. It works wonders on coarse, rough, or fluffy textures that struggle to lock in daily moisture, leaving them completely refreshed, supple, and incredibly soft to the touch.

• How much serum should I apply if my hair is very long?

  If your hair reaches past your mid-back, you will want to use a full three to four pumps of Kérastase Nutritive 8HR Magic Night Hair Serum to ensure total, even coverage. To make application easy and efficient, split your hair down the center into two sections and smooth two pumps thoroughly through each side from the chin downwards. For typical application, one or two pumps will be adequate to cover shorter lengths and ends effectively.

• Can I reapply Kérastase Nutritive 8HR Magic Night Hair Serum in the morning?

  Yes, you can absolutely smooth a tiny fraction of a pump of Kérastase Nutritive 8HR Magic Night Hair Serum onto your mid-lengths and ends in the morning for an extra boost of daily hydration and anti-frizz defense. It acts as an excellent styling primer that tames flyaways and seals open cuticles before you head out the door.

• Does Kérastase Nutritive 8HR Magic Night Hair Serum help enhance curl definition?

  Yes, Kérastase Nutritive 8HR Magic Night Hair Serum is an absolute savior for curly, coily, and wavy hair patterns. Because natural curls lose moisture quickly overnight, this formula works to intensely hydrate the inner fiber, which reduces fluffiness and locks in beautifully defined, bouncy, and distinct curl shapes by morning.

• What does Kérastase Nutritive 8HR Magic Night Hair Serum smell like?

  Kérastase Nutritive 8HR Magic Night Hair Serum features a beautifully evolving fragrance profile designed to complement your evening sleep ritual. It opens with relaxing top notes of ylang-ylang, develops a soft heart of warm tonka beans, and dries down into a comforting, luxurious base of creamy sandalwood that stays gently on your hair all day.
