If you have an oval face shape you're in luck: Ovals can wear practically any hairstyle, including Kristen Stewart's asymmetrical, structured updo. "We saw a lot of asymmetry in the clothes for spring and that plays a big part in the hair," says Syfu.
Super-sleek, center-parted hair like Heidi Klum's can be difficult to pull off, unless of course you're an oval gal. "Clean and simple, flat-ironed hair doesn't work for everyone but it looks good on an oval because they can really wear anything," says Syfu.
Square face shapes can minimize the width of their face with swept-back, volumized waves, like here on Maria Menounos. "The swept-back volume counterbalances your facial width, so it doesn't look as large and the waves help soften the angles of your face," says Syfu.
<a href="A grown-out bob like Anne Hathaway's is another ideal style for those with a square face shape. "It automatically gives you a little volume and looks better because it's not so big through the sides," says Syfu.
Short or long, side-swept or straight across: Bangs are a fab way to soften up a heart-shaped face, as Rihanna demonstrates here. "Bangs work well with this face shape because they soften the corners of the face and reduce its length," says Syfu.
A dramatic side-part and messy waves like Cameron Diaz's are the best way to de-emphasize a round face. "Anything side-swept breaks up the roundness of the face and makes it look more asymmetric," says Syfu.
Minimize fullness by giving your hair lots of height like Hayden Panettiere. "Pompadour styles work great on a round face because the height de-emphasizes the roundness and makes it look squarer while the sleek sides make your face look narrower," says Syfu.
