My hair is black but have one two hairs grow out like copper or rust? Is it too much metal? Anyone know what I mean? Not gray.  ?

nooooooooooooooooooooo

Very few people have hair in which every single strand is exactly the same colour. My hair, for example, is reddish-blonde, or at least it was before it started going grey. But some strands were blonde, some reddish, some brown, some almost white. Now that it's grey, it's white hairs along with some blonde and some brown. Colour variation in hair is totally normal.
