Catherine, Duchess of Cambridge, might be royalty, but her cut is quite common. "This style is all one length that's been curled," says hairstylist Juan Carlos Maciques of the Rita Hazan Salon in New York City. The cut calls for thick, dense hair (otherwise the ends can look stringy) and works on pretty much all face shapes, except for long ones, which it can elongate even more. To create the big curls at the bottom, use a two-inch curling iron to clamp down on the ends of the hair, then roll it up, holding the iron horizontally.
2. LONG, BLUNT LAYERS
"Sofia Vergara's layers start at the collarbone and are cut bluntly and at random, rather than blended, which gives the illusion of thicker hair," Maciques says. The cut suits round and heart-shaped faces best, and it's ideal for straight or wavy textures, since tight curls require too much maintenance.
3. LONG, CHOPPY LAYERS
Minka Kelly's layers are also long, but there are more of them and they are less chunky than Vergara's, starting higher up and going from the chin down. "Minka's cut has more layers that are chopped into the bottom for lightness, which she can get away with because her hair is thick," says Maciques.
"Since Beyoncé's hair is naturally curly, her hair is actually several inches longer than it appears," says Maciques. Her layers are still long and minimal, cut about two or three inches from the ends and thinned at the bottom to avoid a poufy cloud of hair. This cut is best for naturally curly or wavy hair; an iron helps smooth any frizz.
"Emma Roberts's short, evenly blended layers are angled down so they become seamless," Maciques says. "It's the perfect long cut for fine hair, because it gives body and movement without looking straggly." A side part and jaw-length layers in front help shorten her oval face well, but the cut also flatters just about anyone.
6. WITH BANGS
Adding bangs helps soften or shorten square, oval, elongated faces, as is the case with Olivia Wilde, who also incorporates long layers that start at her collarbone. Avoid too-blunt bangs; cut into them so they fall softly at your forehead. Your hair can be thick or thin, but unless it's naturally straight, you'll become a slave to styling.
