Is there a way I can still grow a mustache?

[Zachary C]

I have a scar on my upper lip from stitches and because of this hair no longer grows on that spot. So when my mustache grows out I have a bald spot. I have not yet asked my doctor about it but is there any way I can do something about this bald spot?
