A good round brush is the missing piece in your bangs and blow dryer trifecta. (We like the Ibiza EX2 Extended Handle ($46).) While a blast of hot air can help lock a certain style in place, a round brush is responsible for creating your desired shape. Depending on the style and length of your fringe, the barrel size of your brush may vary, but as a general rule of thumb, smaller barrels are what you'll want to look for. They're an ideal size for extra-cropped lengths.
