So I'm a teenager and I'm trying to get my beard going. I want something good-looking before school starts again (middle of August) and I need some tips. There's a lot of hair on my face, but it's light-colored, thin, and basically invisible. But the only real hair is under my jaw as shown in the pictures below. I also have a pretty thin moustache, but I don't really enjoy it. What should I shave, what should I trim, and what should I keep? This has been growing all summer (no shaving!), so do you think it needs to grow a little more or can it be worked with how it is?
