hi. i dont know about diagnosis, but tattoos are difficult to get rid of, so id take a step back before you go there. the hair dye...well, you're young, and its more OK now to change one's hair color than it was in years past. the products around now aren't as horrible as when i was younger, so...fixing hair dye mistakes and misadventures as lot more easily do-able than in years past, too. a skilled hair colorist, of course, can work wonders.
