Genetics, ethnicity, and even individual hair follicle sensitivity all play a significant role.
The Role of Testosterone in Hair Growth
Testosterone is a hormone that influences hair growth patterns in both men and women. Men generally have higher testosterone levels than women, which contributes to their typically greater body hair. However, the relationship isn't straightforward:
