What would cause the loss of eyebrow hair?

Answer by  sherryk (621)

I think I read somewhere that hypo-thyroidism (underactive thyroid gland) can cause thinning of the eyebrows. Get your blood checked and ask your doctor to refer you to an endocrinologist if need be.

Changes to diet can cause loss of hair, including that on your eyebrows. Often women lose hair right after delivering a baby. Lastly, you might consider a skin allergy or disease like alopecia.

Age may be a contributing factor. You may want to consult with a dermatologist to rule out the possiblity of some kind of alopecia.
