Why Are Pubic Hairs Curly? Understanding Hair Follicle Shape and Genetics

Discover why pubic hairs are curly, explained by hair follicle shape and genetics, and their evolutionary role in protection and moisture retention.

9 views

Pubic hairs are curly due to the shape of the hair follicle. The follicles of pubic hair are oval in shape, which causes the hair to curl as it grows. This curliness can vary greatly from person to person, influenced by genetic factors. The curvature of the hair shaft contributes to the retention of moisture and protection against friction, serving an evolutionary purpose for human bodies.
