Kerastase Premiere 8% (Citric Acid + Glycine) Decalcifying Reparative Pre-Shampoo Treatment - 8.45oz - Decalcify, Repair, Reignite Your Inner Strength

Unleash your hair's "première" strength with the Kérastase Première Decalcifying Reparative Pre-Shampoo Treatment—the essential first step to breaking the cycle of damage that's left your hair stiff, dull, and prone to breakage. Hard water is the silent saboteur, with calcium deposits attacking already vulnerable, porous, and damaged hair, making it absorb three times more calcium than natural hair. This transparent, ultra-sensory gel-texture pre-treatment is formulated with a potent 8% concentration of pure acids, specifically designed to penetrate the fiber and actively decalcify the hair from this mineral overdose. Don't rinse—instead, layer your shampoo directly on top for a maximum dual-action effect that leaves hair instantly smoother and healthier-looking.

This groundbreaking, dual-action formula is engineered for sophisticated damage control, targeting both the surface stiffness and the internal integrity of the hair fiber. The 3% Citric Acid, an organic acid, works from the core to the surface, actively capturing and dissolving the deep-seated calcium that causes rigidity and dullness. Following this, the 5% Glycine, a powerful amino acid, penetrates the inner layers to help repair persistent damage by reconnecting broken keratin links deep within the fiber's cortex. This potent internal reinforcement recreates up to 99% of your hair's original strength, fundamentally rebuilding your hair's architecture from the inside out.

The result is a dramatic, visible transformation—not just a temporary coating. By fortifying the inner structure and sealing the outer cuticle, this pre-shampoo powerhouse drastically reduces breakage by 93% and delivers up to 75% more shine. Experience the luminous "Portofino Summer" scent, a delicate accord of bright mandarin, zesty citrus, and calming orange flower, transforming your repair routine into a true indulgence. This hero treatment is ideal for all hair types struggling with damage, especially from hard water, and is the secret to revealing strands that are resilient, beautifully soft, and incredibly healthy—as if they are renewed.
