New eczema drug has unexpected side effect, growing hair

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.

It's unclear whether this would work for others dealing with hair loss.
