So reading about clays and trace mins has got me thinking about nutritional supplements as a way to rid me of sexy yet unwanted at this time gray hair. (Mrs Yoda actually likes my grays, but Yoda don't. I'll take-it-like-a-man only if I have to.)
Found one of those general review sites:

With all the basic theories on the subject.
The reverse your gray supplements themselves often don't have copper but have iodine, zinc and lots of Bs.
Will kick it around.
