If male pattern baldness is caused by testosterone, why are hairs on top of the head more affected by it and hairs like eyebrows, beard, inside ears etc, are affected less?
In: Biology
It may be because the scalp is quite a tough piece of skin, and has bone right below it, so hairs there don’t have a lot of soft flesh to cushion the follicles, or maybe the circulation is more unreliable
