Kerastase Premiere Decalcifying Repairing Shampoo restores damaged hair by removing calcium buildup caused by hard water. This decalcifying and repairing shampoo transforms into a luxurious foam that gently cleanses the scalp and hair, addressing the calcium overdose that weakens treated locks.

Developed with citric acid and glycine, it deeply eliminates calcium overdose and begins repairing hair from the inside out. By restoring keratin links within the hair shaft, the formula targets damage at the core, leaving strands stronger and more resilient. The sulfate-free formula is designed to support comfort and manageability without stripping moisture.

The result is hair that feels smooth, manageable, shiny, and buoyant—even in challenging environmental conditions. Suitable for all hair types and damaged hair conditions, it’s a practical choice for anyone dealing with hard-water effects, post-color or post-treatment care, or ongoing repair needs.
