hmmm... my initial blood tests showed my copper as being a little bit high (at the point my hair was really getting grey fast)so I have made a conscious effort the past few months to lessen my intake of copper.

I have read on the web about copper supplements having the ability to turn grey back to brown, but I am truly wondering at this point if that's the real issue. Extra copper maybe is effective when a person has too much of other (unwanted) metals perhaps? Too much copper is known to cause cancer and other problems, as our friend Sandi well knows.

Anyway, mine is turning back to brown without copper, matter of fact I avoid supplements with copper altogether if possible, though most have some, but some have way too much in my opinion. I think I get enough copper just from the water line in the kitchen tap and the copper bottomed pots, which are on their way to the garbage can.
