I guess that goes for eyebrows and other body hair in general, but it seems like hair loss with age is very specifically only on top of the head and nowhere else.

My understanding is it is hormonal and governed by androgens, testosterone, and DHT. Depending on a man’s levels and how sensitive their follicles are, it will affect how their scalp or beard grows. It can also be genetic/inherited and they are more likely to bald as they get older. Medication is usually aimed at hormonal causes and combined with something like minoxidil, which is a vasodilator.
Women also go through something similar, except the beard part for most women.
