Kerastase  Premiere  Rebuilding Decalcifying Shampoo for Damaged Hair A chelating shampoo with a rich formula and dual action that removes calcium and strengthens and regenerates damaged hair. It works inside and on the surface of the hair. Première repair decalcifying bath is a chelating regenerating shampoo for all types of hair overloaded with treatments or damaged hair. This professional shampoo gently cleanses the scalp and hair. At the same time, it removes calcium from hard water, which makes damaged or bleached hair even more dull, lifeless and weak. It regenerates the hair from the inside, reduces its brittleness and restores its healthy appearance. The creamy, luxuriously foaming shampoo helps rebuild the keratin bonds in the hair fiber, regenerating it from the inside. It makes the hair smooth and manageable, shiny and elastic.  For the best results, we recommend applying the Première nourishing decalcifying bath to the ultra-repairing decalcifying concentrate previously applied to the hair before the Première leave-in bath. Combining it with other products from the Première range, e.g. a mask, will additionally help regenerate and rebuild damaged hair. How to use: Apply to wet hair, directly onto Première Ultra-Repair Decalcifying Concentrate. Massage until you obtain the consistency of an emulsion. Rinse thoroughly.
