'Our first pre-shampoo treatment that removes calcium and fully repairs all types of damaged hair.

Calcium in water can further damage already delicate over-processed or lightened hair. Because it’s more porous, damaged hair absorbs 3 times more calcium than natural hair. This treatment’s concentration of pure acids has a dual action: it decalcifies hair from this calcium deposits, and repairs it from the inside out, restoring hair strength, and reversing its stiff, dull appearance.
