Overnight Leave-in Treatment with Hyaluronic Acid for Sensitized Blonde Hair

The Kérastase Blond Absolu Sérum Cicanuit 90 ml is the professional overnight serum designed for blonde, bleached and dry hair that needs intensive nourishment and repair during sleep.

Its innovative lightweight gel-cream texture works overnight to restore the hair fiber, reduce breakage and control frizz without weighing the hair down. Upon waking, hair appears stronger, softer and visibly more hydrated.

Overnight Repair for Bleached Blonde Hair

During sleep, the hair fiber can be more vulnerable to friction and mechanical stress. Cicanuit creates a protective veil over the most damaged areas, promoting overnight recovery.

Formula with Hyaluronic Acid and Edelweiss

• Hyaluronic Acid: intensely hydrates and improves elasticity and resilience.

The result is a complete treatment to maintain a healthy, luminous and disciplined blonde.
