Author and Disclosure Information

After a haircut, this 15-year-old boy developed papules and hair loss on the back of his head. The fact that he was African American helped us to zero in on the diagnosis.

A 15-year-old African American boy with no previous medical problems presented with a 2-month history of hair loss and pruritic papules on the occipital scalp that had developed after a barber shaved the area. Physical examination revealed 2 dozen 1 to 2 mm keloidal papules on the posterior neck and occipital scalp with areas of focal crusting (FIGURE).

The patient had no history of trauma or previous keloid/hypertrophic scar formation. However, he had a similar episode a year earlier after shaving the same area. During that occurrence, the papules had cleared one month after applying rubbing alcohol.
