KÉRASTASE Première Decalcifying Repair Shampoo 16.9 fl oz — Removes Calcium Buildup, Strengthens & Smooths Damaged Hair

KÉRASTASE Première Bain Décalcifiant Réparateur is a decalcifying, repairing shampoo that gently eliminates calcium buildup while strengthening and smoothing damaged hair.

This concentrated 16.9 fl oz shampoo is formulated to dissolve mineral and calcium deposits that accumulate from hard water and product residue, helping hair look and feel cleaner, stronger, and more manageable. Its repair-focused formula targets weakened fiber to rebuild resilience, reduce roughness, and enhance shine without stripping natural moisture.

How does this shampoo remove calcium buildup without overdrying?

The formula uses gentle decalcifying agents that lift mineral deposits and residue while preserving the hair’s natural hydration. It cleans effectively on the first lather and rinses clear, so hair isn’t left feeling stiff or brittle.

• Designed to dissolve mineral and calcium deposits from water and styling products
• Gently cleanses without harsh sulfates that strip moisture
• Smooth rinsing action reduces post-wash roughness
• Suitable for frequent use when combating hard-water buildup

What strengthening and repairing benefits can I expect?

The shampoo supports reconstruction of weakened hair fiber to restore tensile strength and reduce breakage during styling. According to product performance metrics, it recreates up to 99% of the hair’s original strength while improving smoothness and shine.

• Targets internal fiber repair for improved resilience
• Leaves hair up to 2x smoother to the touch
• Enhances surface radiance — up to 73% shinier appearance
• Prepares hair for follow-up treatments like conditioners or serums

How should I use it for best results?

Apply to wet hair, emulsify to activate the decalcifying action, then rinse thoroughly. For very heavy buildup, a second light lather can improve results; follow with a conditioner or treatment to complete the repair ritual.

• Wet hair thoroughly before applying
• Work into a rich lather focusing on roots and areas with residue
• Rinse completely and repeat only if needed
• Pair with KÉRASTASE treatments for optimal repair and hydration

Who is this for: This shampoo is ideal for people with damaged, chemically treated, or heat-stressed hair who also contend with hard-water mineral buildup or frequent product layering. It suits anyone seeking a targeted cleanse that both removes deposits and rebuilds hair strength, especially those wanting smoother, shinier hair without aggressive stripping. Safe for regular use as part of a rebuilding haircare routine; follow with complementary KÉRASTASE conditioners or masks for deeper nourishment.
