Kérastase Nutritive 8H Magic Night Serum for Dry Hair

8H Magic Night Serum

by Kérastase Nutritive

Available in Canada at Curious Salons

For:
Dry, frizz-prone, dull or dehydrated hair that needs overnight nourishment, softness and lightweight hydration without a greasy or heavy finish.

Kérastase Nutritive 8H Magic Night Serum is a luxurious overnight leave-in treatment created to nourish dry hair while you sleep. Inspired by nighttime skincare, its lightweight cream-serum formula works for up to eight hours to restore hydration, soften the hair and reduce visible frizz. Anti-dryness polymers help provide immediate care, while niacinamide, glycerin and plant-based proteins support the hair’s protective barrier and replenish essential moisture.

Applied before bedtime, the serum helps protect the hair from friction against the pillow while conditioning dry lengths and ends. By morning, hair feels softer, smoother, more manageable and beautifully radiant — with no need to rinse.

Who It’s For:

• Dry or very dry hair
• Frizz-prone hair
• Dull or lacklustre hair
• Dehydrated mid-lengths and ends
• Hair affected by heat styling or environmental dryness
• Hair that feels rough, stiff or difficult to manage
• Fine, medium or thick hair needing overnight nourishment

What It Does:

• Provides overnight hydration for up to eight hours
• Nourishes dry lengths and ends
• Helps strengthen the hair fibre
• Reduces the appearance of frizz
• Improves softness and manageability
• Helps protect hair from pillow friction
• Supports the hair’s natural moisture barrier
• Leaves hair smoother and more radiant by morning
• Absorbs without leaving a greasy or heavy residue
• Requires no rinsing in the morning

When To Use:
Apply before bedtime whenever dry hair needs additional hydration, softness and overnight nourishment. Use nightly or as often as needed as the final step in your evening haircare routine.

How To Use:
Dispense one to four pumps into your hands, adjusting the amount according to the length, thickness and dryness of your hair. Distribute evenly through the mid-lengths and ends of dry or towel-dried hair. Avoid applying directly to the scalp or roots, particularly on fine hair. Leave in overnight. There is no need to rinse in the morning. Style as desired.
