Why don’t men go bald around their beard like they do on their heads?

Because it is different types of hair, and they react differently to hormones!  

The main culprit is Dihydrotestosterone, a hormone that starts being produced during/after puberty, which causes both the production of beard/body hair, and also has the side effect of causing baldness. 

It obviously isn’t as simple as getting more bald as you get more beard hair, because there are other factors, including genetics, that contribute to both, but Dihydrotestosterone is a contributing factor to both, and there is not currently anything that we are aware of that contributes to “beard balding.”
