The Concentré Décalcifiant Ultra-Réparateur from the Première linedeeply repairs all types of damaged hair.

The calcium in hard water can damage already weakened/sensitized hair. When hair is damaged, it becomes porous and absorbs daily aggressors like calcium, entering a cycle of persistent damage.

The unprecedented 8% concentration of pure acids in this professional treatment has a dual effect: it eliminates excess calcium from the hair, which is responsible for breakage, and repairs it from within by rebuilding the internal bridges of the hair fiber*. Hair is stronger, healthier, shinier, and full of vitality. 99% of its original strength is restored**

Leave the Concentré Décalcifiant Ultra-Réparateur to act for 5 minutes, then apply the Bain Décalcifiant Réparateur to descale and repair in depth.

Apply the Repairing Fluid Foundation or Repairing Filler Mask to repair the surface and add softness. Complete the routine with the Fundamental Filler Serum and/or Repairing Gloss Oil to protect from heat and add shine.
