Which statement about hair follicles between sexes is true?

• A. Hair follicles are only on the scalp
• B. Follicles are equally distributed
• C. Women have more follicles than men
• D. Males have more follicles than women

Answer: (D)

Differences in hair growth between the sexes are mainly driven by hormones, especially androgens. Both men and women have hair follicles all over the body, but the density and the type of hair (vellus versus terminal) that develop in a given area are influenced by hormonal status. In men, androgens tend to produce denser terminal hair in regions such as the face and torso, which can make it seem like there are more follicles contributing to visible hair in those areas. That practical, clinical observation underpins the choice that males have more follicles in the contexts relevant to hair removal practice, even though the exact follicle count per person isn’t strictly fixed and can vary. The other statements aren’t accurate because follicles aren’t exclusive to the scalp, their distribution isn’t uniform across the body, and women don’t consistently have more follicles than men.
