That's the other reason I keep it short, it starts to go all afro on me if I don't.
I've known quite a few people who had "brillo" type hair when it was short, but then they grew it out long and wow, what a difference. My ex actually had horrible hair as a teen when it was short (saw proof in pictures). By the time I met him, he had grown it out and had long gorgeous hair almost as long as mine and straight as an arrow. If he cut it short now, I'm sure it would become brillo again.
For those trying to grow your hair out, YES, there is definitely an awkward stage where the hair is too long to be considered short hair and too short to be long hair, may stick up, look odd, etc., but don't give in. Let it grow a few more months, and you'll see it won't stick up anymore, won't look odd, it just has to re-invent itself. Or maybe even have it styled, put long layers on the sides or some other thing to help get it through that in-between, awkward stage. Most girls I know like longer hair on guys.
