Effasol Color Remover DOES NOT RESTORE HAIR TO ITS NATURAL COLOR. It removes the tint; revealing the underlying lightened base. Permanent hair color first lightens, then deposits color. Effasol Color Remover removes the color deposit, but leaves the hair in its lightened state as the natural color is no longer in the hair. Effasol Color Remover allows you to eliminate unwanted artificial hair color and re-color on a clean base.
