You Have Short or Thinning Eyebrows
If you are losing hair from the outer edges of your eyebrows you may have an underactive thyroid. Your first instinct might be to pull out the eyebrow pencil, but if your eyebrows are thinning or have even disappeared, on the outer edge, it’s time to have your thyroid checked.
Once you are properly diagnosed and treated it’s very likely that your eyebrows will gradually grow back in.
