If you don’t already know your face shape, stand facing a mirror with your hair pulled straight back and look at the angles of your face, especially around your forehead, cheekbones, and jawline. If you need to, draw the outline of your face on the mirror in lipstick or shaving cream to help you figure out the shape. People with round faces often believe that they can’t pull off short hair because it will make their face look too wide. However, as long as you pick a cut with extra volume on the top, it can actually help balance out your round face, making it look longer.  For instance, if you have tight curls, you could try a faux-hawk style with plenty of lift to slim your round features. If your hair is straight, you could choose a pixie with choppy layers around the crown. Avoid cuts which hit at the fullest parts of your cheek or right at your jawline. Just below the chin is a good length if you’re looking for a more feminine short style. If you have a sharp jaw and a wide forehead, layers, waves, or curls can help soften your features. Popular styles for this face shape include soft layers, asymmetrical cuts, and side-swept bangs. If you’d prefer to highlight your strong jawline, choose a classic short cut that’s cropped close on the back and sides with a little texture on the top. Heart-shaped faces, also called triangle-shaped faces, are wider across the forehead and narrower at the chin. Short cuts will emphasize the width of your forehead, so it’s best to wear your hair a little longer. If you prefer a short cut, ask your stylist to keep it about 3 in (7.6 cm) long all the way around. Try a 90s-style undercut or a bob with long bangs to balance your heart-shaped face. Oval faces are the most balanced, and you have the distinction of looking good with almost any hair style. Whether you decide to leave your hair long or shave it all off, chances are you’ll pull off the look like nobody else! If you’re contemplating a chop but you’re not sure which direction to go, schedule a consultation appointment...
