Some products live up to the hype — and then there’s Kérastase’s 8H Magic Night Serum. This overnight leave-in treatment has quickly become a cult favorite with our guests and stylists alike. We can barely keep it stocked, and for good reason: it gives you softer, shinier, stronger hair while you sleep. No rinse. No fuss. Just pure overnight hair magic.
8H Magic Night Serum is a luxurious leave-in treatment designed to nourish your hair while you sleep. Think of it as night cream — but for your hair. Apply 1-2 pumps to dry or damp hair before bed, focusing on mid-lengths and ends – no need to apply at the roots. No rinse needed in the morning, just style and go.
🧡 Pro Tip: Apply it on clean, towel-dried hair and braid it before bed for soft, glossy waves in the morning.
Formulated with plant-based proteins and niacinamide, this lightweight cream textured serum works through the night to:
💫 Provide 8 hours of continuous hydration
💤 Reduce friction from your pillow (hello, fewer tangles)
🌙 Leave hair feeling soft, smooth, and manageable in the morning
💪 Strengthen your hair by up to 98%
💨 Fight frizz by up to 84%
We love it for all hair types — from fine to thick, straight to textured. It’s especially magical for:
- Dry or color-treated hair
- Hair that’s prone to tangles, frizz, or breakage
- Guests who want low-effort, high-impact results
It’s a dream solution for anyone who doesn’t have time for deep treatments or masks during the day.
Grab it before it’s gone! We wish we were kidding when we say we can’t keep this product in stock. It flies off the shelves every time we get it in — and once you try it, you’ll understand why.
Want to be the first to know when it’s restocked? Stop by, DM us, or ask your stylist to put you on our Product Waitlist. Your hair will thank you by morning.
