Hair growth on the legs occurs before puberty in both boys and girls. During and after puberty however, androgens can drive hair on the legs in men to become more abundant, course, and dark.
Although there tends to be more uniformity with where hair grows on the upper legs, there can be great differences as to where hear grows from one man to the next as you work your way down the lower legs. The statistics for this particular section were not derived from the survey performed for this site which we have referenced in earlier sections. Rather, it comes from a study performed in the 1960’s that specifically looked at leg and foot hair.[i] This study only looked at two racial groups in the United States – African-Americans (black) and men of European descent (white).
For the vast majority of men, hair is found on the entire thigh. In the chart below, the on the left is the front view of the leg (quads) and on the right is the back view of the leg (hamstrings).
The majority of men (98-99%) will have hair on their lower legs. However, there is great variation when it comes to lower leg hair. One study observed three main hair growth patterns on the lower leg. In the chart below, the on the left is the front view of the leg (shin) and on the right is the back view of the leg (calf).
