KÉRASTASE Nectar Thermique heat protectant cream for medium–thick dry hair, 5.1 oz — anti-frizz, shine & heat protection to 450°F

KÉRASTASE Nectar Thermique is a leave‑in heat‑protecting cream that smooths frizz, boosts shine, and nourishes medium to thick dry hair while shielding strands from heat styling up to 450°F.

This lightweight cream from KÉRASTASE’s Nutritive line combines plant‑derived proteins and niacinamide to replenish moisture, improve manageability, and create a silky finish. Use it after washing on towel‑dried hair to detangle and protect before blow‑drying, flat‑ironing, or air‑drying. The formula aims to reduce breakage from thermal tools while leaving hair softer and glossier without weighing it down.

How does this cream protect hair during heat styling?

The Nectar Thermique formula creates a barrier around each strand that helps reduce direct heat contact and moisture loss when using hot tools. Protection is rated for high temperatures, and the conditioning agents help maintain elasticity so hair resists snapping under thermal stress.

• Shields hair from heat up to 450°F.
• Forms a light coating that minimizes water evaporation during styling.
• Helps preserve fiber strength to reduce thermal breakage.

Will it tame frizz and improve softness without heaviness?

Yes — the product is designed to smooth flyaways and reduce surface roughness while keeping hair supple. Its blend of nourishing proteins and niacinamide replenishes dry areas so strands lie flatter and reflect more light for a polished look.

• Reduces frizz and flyaways for a sleeker appearance.
• Delivers instant softness for easier combing and styling.
• Non‑greasy finish that preserves natural movement.

How should I apply KÉRASTASE Nectar Thermique for best results?

Apply a small, quarter‑size amount to clean, towel‑dried hair focusing on mid‑lengths and ends. Work the cream through with your fingers or a wide‑tooth comb and leave it in — no rinsing required — then blow‑dry or heat style as desired.

• Use on towel‑dried, shampooed and conditioned hair.
• Distribute from mid‑lengths to ends; avoid roots for lighter hold.
• Style with heat tools or let hair air dry for softer results.

What nourishing ingredients are inside and what do they do?

The formula includes plant‑based proteins that replenish nutrients and support moisture retention, plus niacinamide which helps lock hydration into the hair fiber. Together these components improve manageability and add a healthy-looking sheen without a heavy residue.

• Plant‑derived proteins: restore nutrients and support moisture balance.
• Niacinamide: helps retain hydration and improve hair resilience.
• Light conditioning agents: detangle and enhance shine.

Who is this for: KÉRASTASE Nectar Thermique is best suited for people with medium to thick hair that is dry or prone to frizz and heat damage. It’s ideal for anyone who regularly uses thermal styling tools or wants to improve softness, manageability, and shine without adding weight. If your hair needs targeted nutrition and daily protection while maintaining natural movement, this leave‑in cream offers a salon-grade finish at home.
