Heavy metals, iodine and hair color

My hair is turning back to the original color--brunnette. Loving it. Had about 15% gray. Im using henna for the rest. I think that the key is getting rid of the heavy metals including hair dyes. And the heavy metals in the body. I always felt sick when I got my hair dyed (in the past 5 years). I hated it. I knew something wasnt right about the dyes. Tweet
