about six months ago I started to see a tiny loss of hair at the right lower part of my mustache, and the balded area kept increasing from right to left and now it reached the middle and sopped. If I dont shave this baded area the hair grows slowly white hair, the rest normally growing black. I may say that started to show, maybe after my teeth Xrays, but only thye right side has this problem.
Please help me, what to do, thank you.
