Why does hair grow more on your head than legs?

Hair grows more on your head than on your legs primarily due to differences in hair follicle density, growth cycles, and hormonal influences. Scalp hair has a longer anagen (growth) phase, allowing it to grow longer and thicker, while leg hair has a shorter growth cycle, leading to less overall growth. Additionally, hormonal factors, particularly androgens, can affect hair growth patterns, contributing to the differences between body and scalp hair.
