How does evaluating androgenetic alopecia differ between genders?

• A. Men: General thinning over the crown; Women: Pattern baldness at the front hairline.
• B. Men: No hair loss; Women: Sudden complete baldness.
• C. Men: Generalized thinning over the crown; Women: No thinning.
• D. Men: Male pattern baldness, common. Women: Generalized thinning over the crown, unknown.

Answer: (D)

Pattern of hair loss differs by gender: men typically show classic male pattern baldness with recession at the temples and thinning at the vertex, while women usually have diffuse thinning across the crown with the frontal hairline often preserved. This difference in presentation is why the best choice states men have male pattern baldness and women have generalized crown thinning. In women, thinning can be more variable and often less dramatic, reflecting hormonal influences on follicle sensitivity, but the hallmark is crown-dominant thinning rather than a front-hairline recession. The other descriptions don’t match the common patterns seen in each gender.
