I'm concerned about mercury and other heavy metals, and I've read that many hair dyes contain them. Egads! Since I'm already concerned that I may be suffering from heavy metal overload, I'm looking to switch hair color, and I'd like to try yours. I see references to many other toxins on your site, but no mention about heavy metals. Have your formulas been tested for metals?
(P.S. To all reading this: I think my gray hair has been CAUSED by the metals in my system. I'm about to embark on a heavy metal detox. I'll keep you posted about gray reversal. I'm thinking I may be able to return to my natural color and won't need to be coloring my hair for the rest of my living days! Oh, joy!)
Here's hoping the answer is, "we're metal-free!" Good job on looking out for us, EcoColors. All of us toxic folks sure do appreciate it.
