KÉRASTASE Nutritive Leave-In Cream for Medium to Thick Dry Hair, 1.69 oz — Lightweight, Heat-Protects to 450°F

KÉRASTASE Nutritive Leave In is a lightweight, nourishing leave-in cream that detangles, reduces frizz, and protects medium to thick dry hair from heat up to 450°F.

This leave-in styling cream is formulated to add targeted nutrition and manageability to medium and thick hair that tends toward dryness. Enriched with plant-based proteins and niacinamide, it helps maintain moisture balance while smoothing the hair fiber to make styling easier. Use it on towel-dried hair before blow-drying or heat styling to get a polished finish with less breakage and fewer flyaways.

How does this product protect hair when I heat-style?

The formula creates a lightweight barrier that helps shield strands from thermal stress up to 450°F, reducing surface damage during blow-drying, flat ironing, or curling. Protection is combined with conditioning ingredients so hair feels softer rather than stiff. It’s designed to work under heat rather than replace a styling step.

• Thermal protection rated to 450°F
• Lightweight cream that rests on lengths and ends, not the roots
• Works under both blow-dry and hot tools

Will it help with detangling and frizz control?

Yes — the Nutritive Leave In smooths the hair cuticle and provides slip to make combing easier, cutting down on breakage from brushing wet hair. It also helps reduce static and flyaways for a sleeker look with improved shine. The result is hair that’s easier to style and manage daily.

• Improves comb-through by adding slip to damp hair
• Reduces frizz and flyaways for a more polished finish
• Enhances shine without weighing hair down

What nourishing ingredients are included and how do they work?

The cream blends plant-based proteins to replenish and support the hair fiber with niacinamide to help retain moisture. These ingredients work together to strengthen strands from the outside and help hair maintain hydration for longer. The formulation focuses on visible manageability and touchable softness rather than clinical repair claims.

• Plant-based proteins to add nourishment and improve texture
• Niacinamide to help lock in moisture and support long-lasting softness
• Non-greasy emollients to leave hair manageable and touchable

How should I use it for best results?

After shampooing and conditioning, apply a quarter-size amount to clean, towel-dried hair, focusing on mid-lengths and ends. Do not rinse; either blow-dry or air-dry and finish with heat styling if desired. Combine with other Nutritive collection products for an optimized routine.

• Apply to towel-dried hair: mid-lengths to ends only
• Do not rinse—style by blow-drying or air-dry
• Use with Nutritive shampoo, mask, or night serum for fuller benefits

Who this is for: KÉRASTASE Nutritive Leave In is designed for people with medium to thick hair that tends to be dry, unmanageable, or prone to frizz. If you regularly use heat tools, want easier detangling, and prefer a lightweight cream that adds nourishment without flattening your hair, this product fits into daily styling and care routines. It’s not intended for scalps that need oil-control; focus application on lengths and ends for best effect.
