So you cut your hair off, and now you miss it. it'll grow back. (my hair is down to the middle of my back) I've cut my hair off a few different times. Whenever my hair is short I like putting gel in it and doing weird stuff (something I can't do now that it's long again). But hair grows on the head about the same for everyone, about a half inch a month.

You could also shave your head and get a fuckin' tattoo on your skull
