Everyone says excess zinc can cause a copper deficiency and on this forum people think topical or dietary copper can sometimes restore hair color (also suggested by Dr. Peat). But zinc is such a popular supplement that lots of people like @youngsinatra will overdose for various reasons.
So I was expecting lots of cases of children binging on zinc gummies or whatever and going completely gray but I didn't see any. I might have missed a case or two but I would expect it to be common.
I just thought it was an interesting question so I'm throwing it out there since there's some debate on the copper narrative.
