Kérastase Chroma Absolu Sérum Chroma Thermique is a colour-protecting, heat-protecting leave-in serum for colour-treated hair. It shields colour and the fibre against styling heat while smoothing and detangling — for radiant shade and a polished, glossy finish.

Benefits
  • Colour and heat protection — guards shade and the fibre during blow-drying and styling.
  • Smooth, detangled hair — eases combing and tames frizz.
  • Glossy finish — adds luminous shine without residue.
  • Lightweight — absorbs fast, never weighs hair down.
How to use
  1. On towel-dried hair, warm a small amount between your palms.
  2. Apply from mid-lengths to ends, avoiding the scalp.
  3. Comb through, then blow-dry or heat-style.

Why our stylists rate it
From the Partners Hair team
Kérastase Chroma Absolu Sérum Chroma Thermique is a leave-in anti-frizz heat-protecting serum for colour-treated hair. Part of the Kérastase Chroma Absolu range — the brand's dedicated colour-care line. Lightweight serum that smooths the hair fibre, protects colour, and shields against heat styling.

Best for: colour-treated hair of any texture that is regularly heat-styled; coloured hair seeking daily anti-frizz protection plus colour preservation; the leave-in priming step in a Chroma Absolu routine paired with Bain Chroma Respect (or Bain Riche), Fondant Cica Chroma, and Masque Chroma Filler.
Less suited to: severely damaged hair primarily needing protein reconstruction with heat protection (use Resistance Sérum Thérapiste); colour-treated blonde hair (use Blond Absolu Cicaplasme); curly hair seeking definition (use Curl Manifesto Crème de Jour); fine hair on a non-coloured routine seeking lightweight heat protection (use Nutritive Nectar Thermique).

Key actives:
- Amino Acid Complex (with Arginine) — reinforces weak hair and rebuilds the fibre from the inside out
- Lactic Acid — traps dulling minerals and seals the hair surface for shine
- Vitamin E (Tocopherol) — antioxidant that protects colour from oxidation and environmental aggressors
- Phenyl Trimethicone + Amodimethicone — conditioning silicones that smooth the cuticle and form a heat-protective film
- Lightweight serum base — non-greasy, no buildup

Benefits:
- Heat protection against blow-drying and heat styling tools
- Preserves colour vibrancy and reduces visible fading
- Smooths the hair surface and reduces frizz and humidity-induced flyaways
- Boosts shine with antioxidant protection from environmental aggressors
- Lightweight finish suitable for daily use, no greasy residue

How to use: Apply to clean, towel-dried hair, focusing on mid-lengths and ends. Distribute evenly. Do not rinse. Blow-dry and heat-style as desired. Can be reapplied on dry hair on day 2 for a quick refresh.

Format: 150ml leave-in serum. Also available in 45ml travel size.
