KÉRASTASE Nutritive Nectar Thermique Heat-Protecting Leave-In Cream 1.69 fl oz — Shields to 450°F, Anti-Frizz

KÉRASTASE Nutritive Nectar Thermique is a lightweight leave-in cream that deeply nourishes medium to thick dry hair while shielding strands from heat styling up to 450°F, reducing frizz and easing detangling for instant softness and shine.

This leave-in styling cream blends plant-based proteins and niacinamide to replenish moisture where hair needs it most and to help maintain strength during heat styling. The product is designed for medium to thick hair types that feel dry, rough, or hard to manage; it layers easily over shampoo and conditioner and stays on lengths and ends without weighing hair down. Use it before blow-drying or flat-ironing to protect cuticles, reduce flyaways, and create a more uniform surface that reflects light for improved shine.

How does this cream protect hair from heat styling?

The formula forms a protective coating along the hair fiber to reduce direct thermal stress when using hot tools. It’s formulated to withstand temperatures up to 450°F and helps maintain moisture balance so hair is less prone to breakage during styling.

• Heat protection up to 450°F for blow-dryers, straighteners, and curling irons
• Lightweight film that minimizes moisture loss during styling
• Designed to be heat-activated for better performance when used with hot tools

What benefits will I notice after using it?

You should see immediate improvement in softness and manageability after a single application, with reduced frizz and easier combing. Over repeated use, hair appears smoother and more resilient thanks to the nourishing properties of plant-based proteins and hydration support from niacinamide.

• Softer, smoother strands and a glossy finish
• Fewer tangles and easier detangling when wet or dry
• Reduced flyaways and less static between styling sessions

How do I apply the Nectar Thermique for best results?

Work a small, pea- to quarter-sized amount into towel-dried hair focusing on mid-lengths to ends; avoid the roots to keep volume balanced. Do not rinse out—blow-dry or air-dry as usual, and you can follow with heat tools if needed.

• Use after shampoo and conditioner on towel-dried hair
• Massage evenly through lengths and ends; avoid scalp application
• Blow-dry or let hair air-dry, then style with heated tools if desired

Is this safe for color-treated or chemically processed hair?

The nutritive formula focuses on replenishing moisture and reducing mechanical stress during styling, making it suitable for many types of treated hair. Because it’s a styling leave-in, pairing it with your color-safe shampoo and mask is recommended to preserve color vibrancy and hair health.

• Compatible with color-treated and chemically processed hair when used with suitable cleansing products
• Supports moisture retention to reduce color fade caused by dryness
• Works well alongside masks and serums from the Nutritive range

Who is this for: KÉRASTASE Nutritive Nectar Thermique is intended for people with medium to thick hair that tends to be dry, frizzy, or difficult to style. It’s a good choice if you heat-style regularly, want a smoother finish and easier detangling, and prefer a non-greasy leave-in that layers with other treatments. For best results, incorporate it into a routine with a nutritive shampoo, hair mask, and targeted night treatments from the same collection.
