don't listen to people that tell you to shave it. It really is a myth.
when I was younger, I couldn't grow a beard and now I have a pretty decent-length beard that I think is getting longer as time passes.
just wait and as time passes insha'Allah you'll start to grow it. don't shave it, though.
it really is about genetics. if you grow it, alhamdulilaah, if it doesn't grow, it doesn't grow and you've done nothing wrong and have nothing to be ashamed of. some people have the beard genetics, some don't. if you do have the beard, though, don't feel pressured by the kuffar and don't shave it. if an employer says something, say it's for religious reasons and insha'Allah they'll respect it as a religious thing
