KERASTASE Blond Absolu Cicanuit Overnight Hair Serum 90ml

KERASTASE Blond Absolu Cicanuit Overnight Hair Serum 90ml is an intensive overnight recovery serum for blonde, bleached, highlighted and lightened hair. Designed to work while you sleep, its lightweight leave-in formula helps deeply hydrate, strengthen and restore sensitised blonde hair, leaving it softer, smoother and more manageable by morning.

Blonde and bleached hair requires additional moisture because the lightening process can damage and dehydrate the hair fibre; KERASTASE continues to position Blond Absolu specifically around maintaining and protecting blonde hair.

Overnight recovery care – Works throughout the night to replenish sensitised blonde hair.

Deep hydration – Helps restore moisture to dry hair affected by bleaching, highlighting and lightening.

Strengthens sensitised hair – Supports weakened blonde fibres and helps improve resilience.

Reduces the feeling of dryness – Helps dry, rough blonde lengths feel softer and smoother.

Lightweight leave-in texture – Provides overnight care without requiring rinsing in the morning.

Ideal for bleached hair – Specifically designed around the needs of chemically lightened and sensitised blonde hair.

What Is It?

KERASTASE Blond Absolu Cicanuit Overnight Hair Serum 90ml is a leave-in night treatment developed for sensitised blonde and lightened hair.

Bleaching can leave the hair fibre more vulnerable to dryness, roughness and damage. KERASTASE emphasises moisturising as an important part of maintaining healthy-looking blonde, bleached and highlighted hair.

Rather than functioning like a conventional styling serum, Cicanuit is designed as an overnight treatment.

Apply it before bed and leave it to work through the lengths while you sleep.

The concept is simple:

Apply → Sleep → Hydrate → Strengthen → Wake Up to Softer Hair

It is essentially the Blond Absolu answer to an overnight beauty treatment for sensitised blonde hair.

Cicanuit vs 2% Pure Hyaluronic Acid Serum

These two Blond Absolu serums have different roles.

2% Pure Hyaluronic Acid Serum → Concentrated hair + scalp hydration, particularly relevant following bleaching.

Cicanuit Night Serum → Overnight leave-in treatment for the hair lengths, focused on restoring softness, hydration and resilience while you sleep.

For very dry, bleached hair, the two can therefore serve different purposes within the same overall Blond Absolu routine.
