KÉRASTASE 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 lifts calcium buildup while strengthening and smoothing damaged hair.

This concentrated professional shampoo is designed to reset hair weakened by mineral overload, styling residue, and environmental deposits. Formulated to gently remove excess calcium without stripping moisture, it helps restore fiber integrity so hair feels softer, looks glossier, and handles better. Use it as a corrective step before your regular routine to increase manageability and improve the performance of subsequent treatments.

How does this shampoo tackle calcium buildup?

The formula targets mineral deposits like calcium that accumulate on strands and at the root, which can make hair feel heavy, rough, and less responsive to care. It lifts these deposits with gentle chelating agents, rinsing them away while preserving natural oils.

• Decalcifying action removes mineral film that weighs hair down
• Concentrated texture for thorough cleansing without over-drying
• Prepares hair for improved absorption of masks and serums

Will it repair and strengthen hair damaged by heat or chemical services?

While primarily a decalcifying shampoo, it includes strengthening ingredients that bond and reinforce the hair fiber. Regular use as part of a corrective program helps recreate much of the hair’s original resilience and reduces breakage during styling.

• Formulated to rebuild internal structure for increased strength
• Supports smoother, less brittle strands after treatment
• Designed to work with KÉRASTASE in-salon and at-home repair products

How should I integrate it into my haircare routine?

Use this shampoo as a clarifying step when you notice heaviness, dullness, or rough texture from hard water or product buildup. Apply to wet hair, lather, rinse, and repeat if needed; follow with a repairing mask or conditioner for best results.

• Apply to wet hair, massage, then rinse thoroughly
• Follow with a KÉRASTASE mask or conditioner for deep nourishment
• Use periodically—especially after exposure to hard water or frequent styling

Is it suitable for color-treated or chemically processed hair?

The shampoo is formulated to be effective yet gentle enough for treated hair, helping to remove mineral film that can mute color and texture. For color safety, pair it with color-protecting conditioners and limit frequency per your stylist’s advice.

• Safe for use on bleached, colored, and chemically treated hair when used as directed
• Helps colors appear brighter by removing dulling deposits
• Best used as a corrective step rather than daily wash for color longevity

Who is this for: KÉRASTASE Première Bain Décalcifiant Réparateur is ideal for clients and at-home users who struggle with hard-water effects, mineral or styling-product buildup, and weakened hair fiber. It suits anyone looking to reset their hair’s texture and strength before deeper repairing treatments—particularly people with dry, brittle, heat-styled, chemically processed, or dull hair seeking professional-caliber clarification paired with restorative benefits.
