A 62-year-old white woman presented with a 1-year history of decreased hair density and itching of the scalp. The hair loss was most prominent along the frontal hairline. She also noted decreased density and then complete loss of both eyebrows. She was in good health except for a history of basal cell cancer and actinic keratoses. She had undergone a hysterectomy at the age of 65 years, and the only medication she used was vaginal estrogen cream. She denied any family history of androgenetic alopecia or other types of hair loss.
