The top 4 bob haircuts (and how to style them)
Hough's stylist, Riawna Capri, found the actress's roughed-up bob so versatile and flattering, she asked for the same cut...from Hough herself. No joke—the shape is so simple, it's tough to mess up. For the most movement and styling options, ask for a gently razored perimeter and light snips to remove weight around the face and ears, where hair tends to stick out naturally.
ALLURE TIP: Whether your hair is fine or thick, it'll hold this effortlessly cool shape with the help of styling cream, like Bumble and Bumble Brilliantine, on the ends for separation that's soft but not spiky.
Although this haircut is named after a supermodel, the Karlie is gloriously low-maintenance. The main layer hovers just below the chin, and thanks to long layers around the whole head and bangs that sweep across the forehead, it's full of bounce and body. Hairstylist Tippi Shorter, who's worked with celebrities such as Alicia Keys, says the look works effortlessly with naturally wavy, thick textures, but fine hair can hold the gentle bends and curves with the help of a styling cream, like Verb Styling Cream. No matter what your hair's texture, you can ditch the dryer—this style looks sexiest a bit disheveled.
When Cotillard debuted this no-nonsense style at the SAG Awards, a reporter called it a "piece of art"—and that's exactly how it should be treated. "When you have a style this precise, you're stuck with it for a while," said hairstylist Mika Fowler, who gave Olivia Munn a similarly sharp cut. The magic behind this polished style, which suits thick hair, is committing to your part, says stylist Andy LeCompte; cutting it while it's in a deep side part gives you the most freedom and softens even strong jawlines.
ALLURE TIP: The frizz-prone need not apply. If hair's not sleek, the asymmetry ends up looking like a messy accident, not an intentional decision. Finish off a blowout with a smoothing serum, like Wella Professional Oil Reflections.
For a versatile cut that works on almost any face shape, try Blunt's piecey lob. The key here is strategic layer placement, says Laini Reeves, Blunt's stylist. "This cut feels airy, not like a heavy curtain, because of the light layering around the perimeter."
ALLURE TIP: Reeves recommends taking stock of your favorite features before booking a cut: "Slicing in layers near your cheekbones will draw attention to your nose, so you better love its shape." To get Blunt's lived-in waves, twist hair away from the face as it dries and finish with Serge Normant Meta Sheer Dry Oil Finishing Spray.
