A round face on a woman can give her a cherub-like innocence and make her appear younger than she truly is. But of all the shapes, a round face is the most difficult to "dress" because it lacks definition in all but one place: the cheeks. If you are a round-faced woman it is smart to find a haircut that minimizes your prominent cheeks while creating a bit of definition throughout the soft edges of your face.
Trendy round-faced girls who are in need of an up-to-date haircut should follow in the footsteps of Hollywood starlet Gwyneth Paltrow, who underwent a trendy hair transformation in 2008. The classic round-faced beauty dropped her long waves in favor of a bob. Typically, traditional bob haircuts work against the shape of a round face by accentuating its width, making it appear chubby. But a shoulder-length bob visually slims the face by framing it with long layers. Nicole Richie (in 2006 and 2007) and Heidi Klum (in 2009) have sported this look to great reviews.
Face-framing layers are flattering to a fuller face because they minimize volume on the cheeks by detracting attention from cheekbones and calling attention to the places where the layers rest. Hair should be shoulder-length or longer to properly achieve this look. Consider taking the look further by adding cascading, side-swept bangs, which also will divert attention away from the roundness of your face. Celebrities who have achieved success with this look include Vanessa Hudgens (in 2008 and 2009), Cameron Diaz (in 2008) and Carrie Underwood (in 2009).
Many of us simply do not have the time to stylishly maintain a longer haircut. Contrary to common belief, round faces need not stay away from short haircuts. The trick is to have no strands fall above your chin; if you do, the strands will fall at the fullest part of your face. If you're considering bangs with a short haircut, make do without them, as this will create too much activity around your cheeks and have the opposite effect as the one you are seeking. Create a bit of contrast by calling attention to a defined brow and arch. Maggie Gyllenhaal (in 2006), Kirsten Dunst (in 2001) and Charlize Theron (in 2008) are stars who all made the look work.
