2. A 17-year-old African-American boy likes to keep his face clean-shaven, but his skin becomes irritated every time he shaves. He states that his father also has this problem, but doesn’t have a solution.
Diagnosis: Pseudofolliculitis is a common skin condition affecting hair-bearing areas of the body that are shaved. It develops when the free end of a tightly coiled hair reenters the skin after shaving, causing a foreign-body–like inflammatory reaction. Tightly curled hair has a greater tendency to pierce the follicle and the surface of the skin, explaining the relative predominance of pseudofolliculitis in patients of African descent; at least half of black men who shave develop the condition.
