Who It’s For

Ideal for all hair types, especially for anyone who regularly uses heat tools like blow-dryers. For fine hair, start with a small amount to avoid weighing hair down; for thick or coarse hair, apply a slightly larger dab to ensure even coverage. Use as part of your heat-styling routine to protect, smooth, and speed up your blow-dry. The Kérastase Resistance Extentioniste Thermique Blow-Dry Primer is perfect for those seeking a reliable heat protectant hair primer.

Key Ingredients
  • Heat-Protectant Complex — Creates a barrier against heat exposure to minimize damage during styling. This complex is a key feature of the Kérastase Blow-Dry Primer.
  • Smoothing Polymers — Help smooth the cuticle for a sleek, frizz-free finish. These polymers enhance the effectiveness of the professional hair styling primer.
  • Strengthening Agents — Support hair fibers during heat styling to reduce breakage. The Resistance Extentioniste Thermique Blow-Dry Primer is formulated to strengthen your hair.
  • Conditioning Matrix — Enhances manageability and shine without weighing hair down. This conditioning matrix is essential for achieving glossy hair.
How to Use
  • Dispense a small amount of primer into your palm (start with a pea-sized dab for short to medium hair; increase for thicker hair).
  • Distribute evenly through towel-dried hair from mid-length to ends, avoiding roots unless you want extra lift.
  • Comb through with a wide-tooth comb or fingers to ensure even coverage.
  • Blow-dry using your usual technique and heat setting; style as desired.
  • Follow with your regular styling products or tools for your preferred finish. Incorporating the Kérastase Resistance Extentioniste Thermique Blow-Dry Primer into your routine will enhance your styling experience.

Why our stylists rate it
From the Partners Hair team
Kérastase Resistance Extentioniste Thermique is a leave-in heat protecting cream for damaged hair seeking healthy growth and length. Part of the Kérastase Resistance range. Blow-dry primer that strengthens lengths while protecting against heat styling up to 230°C / 450°F.

Best for: damaged hair growing through to longer lengths that is regularly heat-styled; hair prone to breakage during blow-drying or hot-tool styling; the leave-in priming step in the Extentioniste long-hair routine paired with Bain Extentioniste, Fondant Extentioniste, and Masque Extentioniste.
Less suited to: severely damaged hair needing deeper reconstruction with heat protection (use Resistance Sérum Thérapiste); hair primarily concerned with general damage rather than length retention (use Resistance Ciment Thermique — protects to 180°C); colour-treated blonde hair (use Blond Absolu Cicaplasme); curly hair seeking styling cream definition (use Curl Manifesto Crème de Jour).

Key actives:
- Créatine R Complex — Creatine + Ceramide; reinforces internal hair fibre structure and reseals the cuticle
- Amino acid blend — supports fibre strength and elasticity
- Heat-protective film-forming ingredients — form a smooth, even coating against heat damage
- Lightweight blow-dry cream texture — conditions and primes without weight

Benefits:
- Heat protection up to 230°C / 450°F against blow-drying and heat styling tools
- Up to 90% less hair breakage from blow-drying (Kérastase instrumental test)
- Seals split ends and supports healthy-looking lengths
- Reinforces the internal structure of the hair fibre during styling
- Lightweight cream finish — no weight, no stickiness, suitable for daily use

How to use: Apply a walnut-sized amount evenly through towel-dried hair, focusing on mid-lengths and ends. Detangle with a wide-tooth comb. Do not rinse. Blow-dry, then heat-style as desired. Can also be applied to dry hair before restyling for added protection.

Format: 150ml leave-in cream.
