Men with round faces often find it difficult to get a flattering haircut. A round face shape on a man tends to give him a softer look than a square face shape and can make him seem overweight even when he's not. The best hairstyle for a guy's round face shape is one that elongates his face and emphasizes the straight lines. Learn what styles look good on a guy with a round face and what haircuts to avoid.
Choose a hairstyle that draws the gaze away from the widest part of your face -- usually your cheekbones. Avoid any kind of fullness or body along the horizontal line of your cheeks, and don't end the haircut anywhere from you cheeks to your jaw.
Pick a haircut that squares off on top to add some angular geometry to your profile and minimize the roundness. Even if your hair is curly, give it an even cut on top -- or if wavy, let the waves on top grow a bit long so they flatten naturally.
Avoid bangs. There's nothing wrong with bangs on a man, but you want to keep your full forehead exposed to maximize its length and minimize the roundness of your face shape.
Choose your length carefully. Pick either a very short haircut or long haircut, shoulder-length or below. Avoid chin-length cuts, which round out your face. For short cuts, choose a close-cropped or buzz-cut style. Longer cuts work better with thick hair than with fine -- or with hair that is thin but with a little wave. Avoid long, curly hair if you're going for a guy's-guy look.
Wear men's long hairstyles with an off-center part, with perhaps one side sweeping over your cheekbone for an extra cool look that also thins out your round cheekbones.
