I've been reading about the yet unproven but somewhat suggested link between permanent hair dye (particularly dark hair dye) and cancer. Suspect ingredients: 2,4 diaminoanisole, 2, 4-diaminotoluene, n-nitro-o- phenylenediamine, 4-ethoxy-m-phenylenediamine, H²O² , 4-methoxy-m-phenylenediamine (4MMPD) or 4-methoxy-m-phenylenediamine sulfate (4MMPD sulfate), two coal- tar ingredients. Does your product eliminate these concerns? I'm getting ready to make the plunge to permanent hair color, but I want one that doesn't have the possible association with cancer.
