How do you grow facial hair more, and more evenly?

Nothing you can do to change the amount of hair growing in. fact is, about half of all guys who have facial hair have some patchy or bare spots. Then there are some races that grow almost no facial hair at all. Just pure genetics. Even if your dad has a full beard, your genetics come from him and his parents and your mother and her parents, so you could have totally different facial hair growth.
