Reign in the curls.
"Volume" is more than a dial on your car radio. As your curly or wavy hair grows, so will its volume, which can easily turn your head into a ball of lint.
"Dealing with the roundness is a matter of keeping it shaped, which means the sides must be kept significantly shorter than what's on top, more so than for guys with straight hair," Vaughn says. Even if you want long curly hair, the sides need to be managed. Vaugh recommends focusing on that area when you go in for a trim and talking to the barber about what products you are going to be using to keep your mop from becoming dry and frizzy.
"Skip all the gels and pomades, and just rub in a small amount of hair cream" recommends Vaughn. "It has almost no hold but will weigh [hair] down to help manage the volume." [Malin + Goetz Sage Styling Cream, $20 for 4 oz; malinandgoetz.com]
