Just try it. You might look good, you might not, you might love it, you might hate. You'll never know until you try. Hair always grows back. I know this wrll, I've had my hair almost every way under the sun with the exception of a buzz cut. Just go for it. Keep in mind, a lot less guys are attracted to short hair. You'll always wonder if you don't try. If you don't like it, it'll grow back and you'll be able to say "been there, done that."

If you really want to cut your hair, then just cut it. It's okay, your hair will grow back eventually. But if it really ends up a failure, just wear a wig. :)
