I have a strange thing going on. About 2 months ago I noticed a small area aroiund my eyebrow was a different color than the rest of my skin ( size of maybe a dime at most) I didnt pay much attention, now that eyebrow is turning grey. About 1/2 of it is grey now and it happended quickly. Im 41 and definately paramenopausal.....but I just find this trange and quick. Any ideas??
