Does leg hair mean testosterone?

Hairy legs often indicate higher sensitivity to androgens like testosterone, but it's not a direct measure of your testosterone level, as genetics, ethnicity, and other hormones play big roles. While increased hair growth (especially coarser, darker hair) is a sign of high testosterone/androgen activity, especially during puberty or HRT, it's a combination of hormone levels and how your follicles react that determines hairiness.

Why do men get hairier as they age?

Men get hairier in certain areas with age, like ears, nose, eyebrows, and chest, because their hair follicles become more sensitive to androgens (like testosterone) over time, causing them to grow thicker, longer terminal hairs, while paradoxically, scalp follicles might shrink, leading to thinning, explains Nebraska Medicine. Genetics play a big role in how sensitive these follicles are, but it's the cumulative effect of hormones and aging that changes hair patterns, making some areas bushier while the head thins. 

Do men with high testosterone go bald?

No, high testosterone doesn't directly cause baldness; instead, it's the conversion of testosterone into dihydrotestosterone (DHT) by an enzyme, and whether your genetically sensitive hair follicles shrink from DHT. Some men with high testosterone don't go bald because their follicles aren't sensitive, while others with normal levels do because of this genetic sensitivity. So, genetics and DHT sensitivity, not just high T levels, are the real drivers of male pattern baldness.
