Kerastase Blond Absolu 2% Pure Hyaluronic Acid Repairing Serum - 1.7 oz

Introducing the targeted healing power of the Kérastase Blond Absolu 2% Pure Hyaluronic Acid Serum, a revolutionary translucent gel treatment specifically formulated to repair and hydrate the highly sensitized fiber of bleached, highlighted, or naturally blonde hair. Blonding services, while beautiful, leave hair porous and thirsty; this serum acts like a powerful, instantly absorbing moisture shot, featuring Kérastase’s highest concentration of macro and micro hyaluronic acid. This potent 1.7 oz elixir is a dual-action hero, working simultaneously to repair existing surface damage and create a comfortable, soothing environment for the scalp, making it the essential treatment for preserving the health and vibrancy of all blonde shades.

The unique strength of this formula lies in its immediate, non-greasy absorption and dual-focused application: it’s designed to be massaged into the scalp and distributed through the hair lengths. By applying it directly to the scalp, the serum soothes post-bleaching sensitivity and preserves the scalp’s vital moisture barrier without leaving any heavy or oily residue. For the hair fiber, the ultra-concentrated 2% pure Hyaluronic Acid instantly works to fill the micro-fissures and damage left by lightening, delivering deep, penetrating hydration. This restorative action leads to 95% stronger hair and a measurable increase of 43% shinier hair after just one use, transforming fragile strands into a resilient, luminous mane.

This translucent, leave-in serum is an indispensable part of the Blond Absolu regimen, designed for application on clean, towel-dried hair to maximize the absorption of the active ingredients. Beyond the core benefit of hyaluronic acid, the formula is also enriched with Edelweiss Flower extract, an alpine marvel known for its potent antioxidant properties that shield hair from daily environmental aggressors and softening the sensitized fibers. With its quick-absorbing nature and light, sophisticated floral-citrus scent featuring notes of orange blossom and bergamot, this 1.7 oz serum is the daily secret to maintaining the integrity, strength, and vibrant shine of your gorgeous blonde color.

Highest Concentration of Pure Hyaluronic Acid: This translucent gel serum features Kérastase's highest concentration of both macro and micro Hyaluronic Acid—a powerhouse ingredient that is scientifically proven to hold 1,000 times its weight in water. This ultra-concentrated dose instantly floods the hair fiber with essential moisture, plumping it up to help repair surface damage and strengthen the hair.

Dual-Action Scalp Soothing and Hair Repair: The formula is uniquely designed for application from scalp to ends, providing targeted relief for post-bleaching sensitivity on the scalp while preserving its natural moisture barrier for comfort. Simultaneously, it works on the hair lengths to reinforce and repair the fiber, immediately making hair 95% stronger and significantly reducing breakage.

Exceptional Shine and Damage Correction: The ultra-hydrating power of the serum visibly improves the hair's surface, restoring the natural reflective quality that is often compromised by bleaching and environmental damage. Clinically shown to result in 43% shinier hair after the very first application, it corrects dullness and restores a luminous, high-gloss finish that enhances the vibrancy of any blonde shade.

Antioxidant Protection from Edelweiss Flower: Enriched with potent Edelweiss Flower extract, a resilient alpine plant known for its protective antioxidant properties, the serum actively shields the sensitized hair fibers from daily environmental damage and free radicals. This proactive defense helps maintain the health and softness of the hair, preventing future weakening and color degradation.

Lightweight and Non-Greasy Leave-in: Despite its deep restorative power, the translucent gel serum has a fast-absorbing, lightweight texture that leaves a clean, non-greasy, and non-sticky finish on both the scalp and hair. It is the perfect daily leave-in treatment to maximize hydration and protection without ever weighing down the hair or disrupting your styling routine.
