Kérastase Chronologiste Thermique Régénérant is an age-defying, heat-protecting leave-in for dull, devitalised hair. It shields strands from styling heat while reviving the fibre with Abyssine — restoring shine, smoothness and resilience with every blow-dry.

Benefits
  • Heat protection — shields the hair from blow-drying and styling tools.
  • Revives the fibre — Abyssine helps renew dull, devitalised hair.
  • Luminous shine — replenishes radiance for a healthy-looking finish.
  • Lightweight — absorbs fast without weighing hair down.
How to use
  1. On towel-dried hair, warm a small amount between your palms.
  2. Distribute through mid-lengths and ends, avoiding the scalp.
  3. Comb through, then blow-dry or heat-style.

Why our stylists rate it
From the Partners Hair team
Kérastase Chronologiste Thermique Régénérant is an anti-aging blow-dry primer and heat protectant for mature, dull, brittle, or dehydrated hair. Part of the Kérastase Chronologiste range — the brand's luxury age-corrective system. Lightweight leave-in cream that revitalises lengths and ends while protecting against heat damage up to 230°C / 450°F.

Best for: aging, mature, dull, or fatigued hair lacking bounce and shine; dry, brittle, or thinning lengths that show signs of fibre aging; daily blow-dry and hot-tool styling protection; the leave-in step in the Chronologiste routine paired with Bain Régénérant and Masque Intense Régénérant.
Less suited to: weakened or damaged hair primarily needing structural repair (use Resistance Ciment Thermique or Extentioniste Thermique); colour-treated blonde hair (use Blond Absolu Cicaplasme Thermique); curly hair where curl-definition and frizz-control are the priority (use Curl Manifesto Crème de Jour Fondamentale); fine, thin hair that lacks density (use Kérastase Densifique range).

Key actives:
- Hyaluronic Acid — ultra-concentrated humectant; nourishes the fibre, fills the cuticle, and provides deep hydration; holds 1,000 times its weight in water
- Abyssine — patented regenerating molecule (sourced from extremophile bacteria) that revitalises and fortifies the fibre, with anti-irritation properties for the scalp
- Vitamin E (Tocopherol) — antioxidant; protects from external aggressors such as UV, pollution, and free radicals
- Conditioning silicones — form a smooth heat-protective film and seal the cuticle

Benefits:
- Heat protection up to 230°C / 450°F against blow-drying and hot tools (Kérastase instrumental test)
- 24h frizz-control in 80% humidity (instrumental test)
- Refines and smooths hair texture; cuticles are sealed
- Revitalises aging lengths and ends with bounce and movement
- Protects against environmental damage and oxidation
- Awarded Total Beauty Editors Pick Blowout Cream 2021 and Allure Best of Beauty 2021

How to use: Apply 1–2 pumps to damp hair, working from mid-lengths through ends. Comb to distribute evenly. Do not rinse. Blow-dry, then heat-style as desired. Can also be used on dry hair to smooth flyaways throughout the day.

Format: 150ml leave-in cream.
