Kérastase Blond Absolu Cicanuit is an overnight leave-in treatment for bleached and blonde hair. This lightweight serum works while you sleep — replenishing moisture and reinforcing the cuticle — so dull, fragile blonde wakes up softer, brighter and more resilient.

Benefits
  • Overnight repair — restores moisture and softness while you sleep.
  • Stronger cuticle — reinforces the hair surface to reduce breakage and splitting.
  • Revived brightness — restores radiance to dull or pale blonde.
  • Lightweight leave-in — absorbs fast, with no greasiness.
How to use
  1. After conditioning, towel-dry hair until damp.
  2. Apply 2–3 pumps to mid-lengths and ends, avoiding the scalp, and comb through.
  3. Leave overnight, or style in the morning. Use 2–3 times a week.

Why our stylists rate it
From the Partners Hair team
Kérastase Blond Absolu Sérum Cicanuit is an overnight cream-in-gel hair serum for blonde, bleached, highlighted, or sensitised hair. Part of the Kérastase Blond Absolu range. Lightweight, no-rinse formula concentrated in Hyaluronic Acid and Edelweiss Flower to repair and hydrate the fibre while you sleep.

Best for: blonde, bleached, highlighted, or naturally grey hair that wakes up dry, tangled, or frizzy; sensitised lengths needing nightly recovery between salon visits; reducing pillow-friction breakage; the night-time step in a Blond Absolu routine paired with Bain Lumière or Bain Ultra-Violet, Cicaflash conditioner, and Cicaplasme Thermique before heat styling.
Less suited to: blonde hair primarily needing intensive post-bleach repair on wash days (use Blond Absolu Masque Ultra-Violet for tone + treatment, or layer with 2% Pure Hyaluronic Acid Serum); heat-styled blondes needing primary heat protection (use Cicaplasme Thermique — up to 230°C); brunette or red colour-treated hair (use Chroma Absolu range); non-coloured hair needing general overnight nourishment (use Kérastase Nutritive — 8H Magic Night Serum).

Key actives:
- Hyaluronic Acid (Sodium Hyaluronate) — holds up to 1,000 times its weight in water; fills and heals fibre wounds from within, deeply hydrates and softens overnight
- Edelweiss Flower extract (Leontopodium Alpinum) — alpine glacier flower; powerful antioxidant that protects sensitised hair from oxidative stress
- Conditioning silicones (Dimethicone, Amodimethicone) — form a protective veil against pillow friction without weighing hair down
- Behentrimonium Chloride — cationic conditioner that smooths the cuticle

Benefits:
- Erases up to 55% of overnight discoloration damage (Kérastase instrumental test)
- 74% more hydrated and 89% stronger blonde hair
- Protects against pillow friction, breakage, and split ends
- Lightweight gel-cream texture — absorbs quickly, no greasy residue, no need to rinse
- Wake up to softer, smoother, healthier-looking blonde

How to use: Before bed, massage 2–4 pumps into lengths and ends of dry hair. Avoid the scalp. Leave in overnight — a loose bun or braid reduces morning frizz further. No rinsing needed in the morning. Style as usual.

Format: 90ml leave-in night serum.
