The hair loss gradually worsened, and the site developed a burning and itchy sensation when exposed to the sun. She reports having tried various over-the-counter medicated shampoos and hair-loss treatments, including salicylic acid shampoo, sulfur shampoo, and topical minoxidil, but did not notice any improvement. She also reports occasional fatigue and joint pains but is otherwise in good health.

A. Atopic dermatitis
B. Discoid lupus
C. Lichen planopilaris
