hello. female, 26 years old.is it possible to lose hair in one eyebrow? ive noticed that the hair on my right eyebrow is falling out/thinning, but the left side seems normal. ive never plucked my eyebrows, and they've always been on the bushy side.but now the right one is really thin, it looks far different from my left eyebrow. could this be related to a disease? or hormonal, since its on one side only? is there a big chance that the hair would grow back?
