A buzzed hairstyle is a good cut if your face is oval shaped, or if you have a square jaw. A military haircut leaves an inch or so in the front that can be combed up and waxed. A crew cut features a bit of long hair on the top of your head, but is generally left unstyled. If you want a modern look, try a fauxhawk like the one popularised by David Beckham. This is offers a sporty look for straight hair.
