Refresh damaged hair with salon-grade precision using Kérastase Premier Decalcifiant Repairing Pre-Shampoo Treatment. This targeted pre-wash formula is designed to decalcify mineral buildup and reset strands that have been compromised by hard water, pool chlorine, or chemical processing. By removing deposits before shampooing, it primes hair to receive deeper repair from your conditioner and treatment products.

• Size: 250 ml / 8.45 oz
• Type: Pre-shampoo treatment
• For: Damaged hair needing decalcification and repair
• Key ingredients: Citric acid and glycine
• Effect: Decalcifies buildup, smooths the hair cuticle, and primes strands for conditioning

Mineral deposits from hard water, chlorine, and chemical services can dull color and weigh hair down. This decalcifying step targets those deposits at the surface and within the cortex, helping to restore the hair’s natural sheen and softness. The result is a smoother cuticle, improved manageability, and a more receptive canvas for conditioning treatments that follow.

Who benefits most

• Anyone with damaged or stressed hair exposed to hard water or chlorine
• Color-treated or chemically processed hair needing better conditioning absorption
• Those seeking a proactive pre-wash routine to optimize repair products

How to use

Apply to damp hair before your regular shampoo. Gently work the treatment through the lengths and ends, focusing on areas that feel dry or weighed down, then rinse. Proceed with your usual shampoo and conditioning routine to maximize repair and shine.

Why this stands out

Unlike standard cleansers, this pre-shampoo treatment specifically targets mineral buildup that can compromise color vibrancy and moisture uptake. The combination of citric acid and glycine not only removes deposits but also smooths the cuticle and primes hair for deeper conditioning, delivering salon-grade repair at home. If you’re aiming for easier detangling, improved softness, and a brighter, healthier-looking finish, this decalcifying step is a strategic addition to your routine.

Integrate this into your regimen as a dedicated pre-wash treatment to empower your conditioner, extend color life, and transform damaged tresses into smoother, more manageable hair with lasting shine.
