Round faces are characterized by the ratio between their width and length--a round face is as wide as it is long. People with round faces also tend to have full cheeks and a soft, rounded chin. The most suitable haircuts for round faces are either cropped above chin length, or much longer. Haircuts that are chin-length should be avoided because they have a tendency to accentuate the roundness of a face.
Long layers are one of the best styles and cuts for fine hair and a round face. These cuts add volume to fine, limp hair and elongate a round face shape, making it look narrower, thinner and more refined. Long layers are best because they taper the curvy angles of a round face while the alternating lengths give much-needed body to fine hair, making it look thicker and fuller. Do not attempt to cut your own hair into the long layered look. This cut is best done by a professional stylist for best results. Tell your hairstylist to not take off too much length--ideally, layers should be about two inches or more below the shoulder.
Gentle Waves and Side-Swept Bangs
Side-swept bangs are one of the best ways to slenderize a round face. A side part gives a round-shaped face more definition than a middle part, which draws emphasis to the width of the face. Gentle, loose waves give boost and body to fine hair, especially if it's straight. Straight, fine hair tends to droop and look limp. Styling hair with a slight curl helps add definition, making the locks look thicker.
To achieve this style, part your hair about an inch away from your natural middle and brush to the left or right. Use a curling iron with an inch-wide barrel to create loose waves. Do not curl your bangs, but add texture by flipping them inward or outward slightly. Also, avoid blunt-cut bangs which emphasize the width the same way a middle part does. This cut is beloved by round-faced celebrities like Kate Winslet.
A shag cut has a similar result for fine hair and a round face as achieved by long layers, but it also works well for medium-length hair. The ideal length for a shag cut is anywhere between the chin and shoulder. It is achieved by cutting short, wispy layers throughout the hair, especially at the crown to achieve height. A flat crown will only bring attention to the full cheeks of a round face. Short layers also add volume to fine hair, giving it texture. Ask your stylist to give you uneven, choppy layers in the front and back. If your hair is naturally wavy or curly, keep the shaggy layers longer to avoid extra frizz. Maintain this style by getting the ends trimmed every six to eight weeks. Celebrities like Cameron Diaz (who has a very round face) especially like the shag cut.
