Kérastase Première Bonding Pre-Shampoo Hair Treatment [STEP 1- ACTIVATE REPAIR] deeply restores and intensely repairs all levels of damage for all hair types. This includes damage from heat styling, over-processing, colour treatment, bleaching, and even water in your shower.

Formulated with a concentration of 8% Pure Citric Acid and Glycine, the Pre Shampoo acts on inner & outer hair layers to neutralise dullness and stiffness. The formula rebuilds broken keratin bonds to reduce breakage.

With its transparent gel texture, the Pre-Shampoo dives deep to help repair persistent damage. Hair is left stronger, healthier-looking, and shinier - as if renewed.

Think of it like a skincare routine for your hair. Apply the Première Pre-Shampoo Treatment generously before the shower to damp hair, then after 5 minutes, layer the Shampoo directly on top and lather. Rinse and finish with the Repairing Conditioner as a final step.

The Pre-Shampoo helps:
