Doctors are reporting an unexpected side effect to a relatively new eczema drug -- growing hair. This has only been demonstrated in one patient so far.

A 13-year-old girl started taking the drug called Dupixent. It is intended to treat eczema -- an intensely itchy skin disease.

She also happened to have a severe case of alopecia, which is total hair loss.

Within a year of using the eczema drug, she's sprouted all new hair growth. The announcement is posted on the JAMA Dermatology website.
