Kerastase Premiere Concentre Decalcifiant Ultra Reparateur Ampoules 250Ml

The first pre-shampoo treatment that removes calcium and fully repairs all types of damaged hair.Hard water with calcium can further damage already delicate over-processed or bleached hair. Because its more porous, damaged hair absorbs 3 times more calcium than natural hair. This treatments concentration of pure acids has a dual action: it decalcifies hair from this calcium overdose, and repairs it from the inside out, restoring hair strength, and reversing its stiff, dull appearance.
