I can't seem to grow facial hair on the front of my chin for some reason. Bottom is fine, my sideburns are fine, but I'd like to get from "chinstrap" to "actual beard". From what I've been looking at, it might be genetic, but I'm not sure. I mean, the hair on top of my head is *extremely* dense, and my nails grow to a good length if I let them and are quite strong, so my facial hair should also be healthy, yes?
