Besides contouring, your hair can also provide the illusion of a slimmer face, as artfully snipped tresses can de-emphasize your cheeks and your jawline. If you want to add "angles" to an otherwise round face, stick to wispy layers and texture for better framing. To help you out, here are quick face-slimming 'dos you can try the next time you drop by the salon.
The It Haircut is a slimming 'do because it falls gracefully on the collarbone and frames the neck.
Shaggy layers soften the jawline and downplay chubby cheeks. The ideal length would be to have your locks reach the bra line, so they won't drag your face down too much, making you look older and tired.
A boho-like fringe can help lengthen a round face. Ask your hairstylist to do a texturized cut to draw attention to the upper part of your face: your eyes.
