Kerastase Blond Absolu 2% Pure Hyaluronic Acid Repairing Serum (1.7 oz) - Skincare science for blonde hair: Plump, Repair, and Protect

Say hello to your blonde hair's new holy grail: the Kérastase Blond Absolu 2% Pure Hyaluronic Acid Repairing Serum. Bleaching and highlighting do incredible things for your look, but let’s be real, they leave hair porous, dry, and sensitive—it's just a fact of life for us blondies! This serum acts like a moisturizing skincare treatment for your sensitized hair and scalp, specifically formulated to tackle the structural damage and dehydration that stripping hair color can cause. It’s the ultimate post-bleaching procedure care, ensuring your gorgeous blonde color comes with softness, strength, and irresistible shine.

This innovative formula features Kérastase's highest-ever concentration of Macro and Micro Hyaluronic Acid at a potent 2%. These two molecular weights work in tandem: Macro Hyaluronic Acid plumps the hair fiber for enhanced fullness, while Micro Hyaluronic Acid penetrates deeper to strengthen the internal structure and preserve the scalp's delicate moisture barrier. The result? Hair that is visibly replenished, intensely hydrated, and 95% stronger after just one application, giving you that 'plumped-up' bounce that screams healthy hair.

Enriched with precious Edelweiss Flower Extract, a powerful antioxidant sourced from the Swiss Alps, this lightweight, clear gel serum also offers crucial protection against daily environmental aggressors and damage. Unlike heavy oils or creams, this non-greasy, fast-absorbing leave-in treatment soothes and comforts the scalp without weighing down your hair, leaving behind a delicate, luxurious floral-citrus scent. It's the essential final step in your blonde care routine, transforming fragile, sensitized strands into luminous, resilient hair that feels incredible to the touch.
