Description
Kérastase Première Bain Décalcifiant Réparateur Repairing Shampoo is a targeted cleanser designed to remove hard water mineral buildup while strengthening fragile, damaged hair. This repairing shampoo gently dissolves excess calcium deposits that can leave hair stiff, dull, and prone to breakage.
From the first wash, hair feels softer, smoother, and more resilient. If you are searching for a Kérastase repairing shampoo that restores shine while supporting bond-strength and flexibility, this formula is an essential step in the Première routine.
HOW IT WORKS
Hard water minerals can collect on the hair fiber over time, creating roughness, dryness, and reduced elasticity. This decalcifying shampoo helps lift stubborn calcium buildup so hair can better absorb conditioning and reparative ingredients.
The formula is enriched with amino acids and strengthening agents that support the hair’s internal structure while smoothing the cuticle for a healthier-looking finish. Hair is left clean, refreshed, and noticeably more manageable.
VISIBLE RESULTS
With continued use, hair appears brighter, smoother, and less weighed down by mineral residue. Breakage looks reduced, stiffness improves, and lengths regain softness and movement.
As part of the Kérastase Première system, this shampoo helps maintain long-term strength, clarity, and shine, especially for hair affected by coloring, heat styling, or environmental stress.
TEXTURE AND FEEL
This shampoo creates a rich yet lightweight lather that cleanses thoroughly without stripping. It rinses clean and leaves hair feeling fresh, soft, and polished rather than dry or heavy.
Lengths feel smoother immediately, with improved detangling and a more fluid finish after styling.
WHO IT’S FOR
Ideal for anyone experiencing dullness, rough texture, or breakage linked to hard water exposure. Especially beneficial for:
-
Damaged or over-processed hair
-
Color-treated hair lacking shine
-
Hair that feels stiff or brittle
