Kérastase Discipline Keratine Thermique is a keratin-enriched blow-dry primer and heat protectant for frizz-prone hair. It smooths unruly hair during heat styling while the Morpho-Kératine complex shields against heat and humidity — for a sleek, salon-smooth finish that lasts all day.

Benefits
  • Smooths frizz as you blow-dry — keratin bonds to the fibre for a sleek finish.
  • Heat protection — shields the hair from all styling tools.
  • Humidity resistance — Morpho-Kératine holds the smooth result all day.
  • Lightweight — no greasiness or residue, even on fine hair.
How to use
  1. Apply to clean, towel-dried hair — pea-sized for short to medium, more for longer hair.
  2. Distribute through lengths and ends with fingers or a wide-tooth comb.
  3. Blow-dry immediately. Add a second light layer to ends on humid days.

Why our stylists rate it
From the Partners Hair team
Kérastase Discipline Keratine Thermique is a leave-in smoothing milk and heat protectant for unruly hair. Part of the Kérastase Discipline range. Cream-textured blow-dry primer that smooths frizzy hair while protecting against heat styling.

Best for: frizzy, unruly, or thick hair that benefits from a richer leave-in cream than a spray would deliver; daily blow-dry styling on unruly textures; the leave-in priming step in a Discipline routine paired with Bain Fluidealiste, Fondant Fluidealiste, and Maskeratine — particularly for thicker or more frizz-prone hair than Fluidissime alone can manage.
Less suited to: fine hair that would be weighed down by a cream-textured primer (use Discipline Anti-Frizz Fluidissime spray instead); curly hair seeking definition (use Curl Manifesto Crème de Jour); severely damaged hair primarily needing repair with heat protection (use Resistance Ciment Thermique); colour-treated blonde hair (use Blond Absolu Cicaplasme).

Key actives:
- Morpho-Kératine™ Complex — amino acids + wheat protein extracts + Ceramide-R; coats and smooths the hair fibre for anti-frizz protection
- Lipid blend — restore the cuticle surface and seal in smoothness
- Heat-protective film-forming agents — shield the hair from heat styling damage
- Cream-textured leave-in base — richer than a spray, suitable for thicker hair

Benefits:
- Smooths and disciplines frizzy hair during heat styling
- Heat protection against blow-drying and heat styling tools
- Restores hair fibre homogeneity with each application
- Cream texture coats and softens thicker, denser strands
- Long-lasting frizz control through the styling cycle

How to use: Apply a hazelnut-sized amount to clean, towel-dried hair, focusing on lengths and ends. Distribute evenly with a comb. Do not rinse. Blow-dry and heat-style as desired.

Format: 150ml leave-in smoothing milk.

Before you buy
Common questions

What does Kérastase Discipline Keratine Thermique do?

It is a blow-dry primer and heat protectant that smooths frizzy, unruly hair during heat styling. Keratin strengthens the hair fibre while the Morpho-Kératine complex tames frizz and protects against humidity for all-day smoothness.

Is Keratine Thermique a heat protectant?

Yes — it protects hair from heat damage during blow-drying and other heat tools. Apply it before using any heat tool.

Can I use Keratine Thermique on fine hair?

Yes — the lightweight formula suits all hair types, including fine hair. Use a smaller amount (about half a pea-sized) to avoid any heaviness.

What is the difference between Keratine Thermique and Ciment Thermique?

Keratine Thermique (Discipline range) focuses on anti-frizz and smoothing for unruly hair. Ciment Thermique (Résistance range) focuses on strengthening and repairing damaged, breakage-prone hair. Choose based on your main concern — frizz or damage.
