Okay so I'm a Chinese kid and I look like I'm 13 even though I'm actually 20. What I'm looking for is a hairstyle that looks professional, but most short haircuts just don't work for me.

Like I said, I have a very childish face so short haircuts make that more obvious. Another reason is that I have a fox-type face, long and thin, feminine if you will, and short hair kinda makes the top look "too big". The last and final reason is that when short, my hair poofs up like a monster and that makes me look like I have some sort of afro or something.

Most of my life I've had long hair, but now I'm just getting frustrated with looking like some sort of wannabe rock star (plus people keep thinking I'm Japanese) and I really just want a nice haircut that looks cool and one that won't lower my chances of getting a job. Suggestions?
