A 17-year-old White girl presented for evaluation of “hair loss” that had begun approximately 1 year prior to presentation. Pertinent patient history included emotional stress and use of heating tools to straighten and blow dry her hair, with reported use of 3 times per week. She had no other significant medical history, and she took no medications.
Physical examination. The patient appeared comfortable and well-nourished, and no signs of developmental delay were apparent. Examination of the right side of the scalp revealed mild distal hair breakage with multiple small nodes on the proximal hair shaft (Figure 1). Hair in this area was also significantly shorter than the surrounding hair (Figure 2). The remainder of the scalp, head, and neck examinations were unremarkable. A focused review of systems, including immunologic, endocrine, and integumentary, disclosed no abnormal findings. The patient also denied any history of psychological disorders or inability to resist the urge to pull out hair.
