The right hairstyle can take a strong jaw from so-so to stunning. Finding that flattering 'do can look pretty perplexing, but don't worry; the perfect jaw-flattering style can take on many looks (and lengths). A few key features -- such as texture, part placement and layering -- are always held in high importance when it comes to fitting and flattering a square jaw.
Play the Part
The perfect hair part can work wonders when trying to suit a square jawline. You'll want to keep the part soft and slight; one that's too deep and severe will only add emphasis to your jawline, throwing your face out of balance. Try a middle part to play up the center of your face, or one that's slightly off-center to draw the eye up toward your forehead. Either type will draw your hair toward the sides of your face, slightly softening the angles of your jawline.
Turning to Texture
To turn down the harshness of a square jaw, turn up the texture of your hair. Use a medium-to large-barreled curling iron to give your hair some temporary waves that will offset the sharpness of your jaw, or add some permanent waves with a chemical perm. For supersoft beachy waves, add a little styling cream in the morning or simply wear your hair in braids overnight.
Lovely Layers
For balancing the shape of a square jaw, properly-placed layers are key. You'll want to emphasize the top of the face, to balance it with your jawline. Try a cut with short layers that start at the eye area and end just past your cheekbones, with the longest layers slightly curved about an inch below your jawline. Want to keep your long locks? Wear longer layers in a bouncy shag style, with the shortest layers hitting just below your chin, as hairstylist Jimmy Paul tells "Allure" magazine.
Bang Busters
You'll want to avoid adding angular shapes to your face, so stay away from bangs that are cut straight across your forehead. Sweeping bangs with a side part look fabulous with a square jaw, maintaining the strength of your bone structure while balancing the face with sexy, face-framing curves. Keep your bangs at least eyebrow-length for a look that's strong, not severe.
