Choose a right fringe according to your face shape. To find out your face shape, take all hair away from face (make a ponytail) and 1-2 meters away from the mirror take a long look at your face.
Fringe can make you look younger and prettier. Try to compare your face shape with four main face shapes – round, square, oval and heart. If you want bangs but not sure if it fits you, try to clip hair in the shape of fringe that you want using bobby pins or just your hands infront of the mirror.
You can also try using special computer programs, in which you can try any hairstyle after you upload your picture. Fringe can change your style dramatically. It can cover too wide or too small forehead, hide not so pretty hair line, hide wrinkles, flatter your face shape, bring out eyes and cheekbones.
