KERASTASE Blond Absolu Cicanuit Serum - Overnight Repair for Blondes

In this review the KERASTASE Blond Absolu Cicanuit Serum is examined as an overnight treatment for color treated and blonde hair. The bottom line: it is best suited for someone with fine to medium, color-treated hair who wants a lightweight overnight boost of moisture and improved softness without weighing strands down. The formula focuses on hydration and smoothing using hyaluronic acid and plant-derived extracts, making it a targeted choice when the main priority is restoring softness, reducing frizz, and preserving color vibrancy.

Key Features

• Overnight treatment: Designed to be applied before sleep to hydrate and treat hair while you rest, saving styling time in the morning.
• Hyaluronic acid: Adds visible moisture to dry, color-treated strands, helping hair feel softer and more pliable after use.
• Edelweiss flower extract: Provides antioxidant care aimed at protecting fragile, lightened hair from environmental stressors.
• Lightweight formula: Leaves hair feeling weightless and manageable, which customers report is particularly good for fine hair types.
• Frizz control and shine: Smooths damaged ends and adds noticeable shine without a heavy residue.
• Pleasant scent: A subtly fragranced finish that customers consistently note as enjoyable rather than overpowering.

Who It's For

This serum is best for people with color-treated, bleached, or highlighted hair who need extra overnight hydration and softening. It suits fine to medium hair textures especially well because the lightweight formula provides moisture without heavy buildup, making morning hair easier to style.

Those with very coarse or severely damaged hair looking for intense reconstructive treatment may prefer a heavier mask or in-salon repair; likewise, anyone avoiding fragranced products should check ingredients before purchase since this product has a noticeable scent.
