Get A Hollywood Hair Style - Stars Before and After

America Ferrera

The Ugly Betty star's flowy length gave her a youthful look, while her shorter style "lifts and frames her face, making her look more chic, sophisticated and fun!" says celebrity stylist Edward Tricomi. He recommends applying finishing cream as a last step to get a smooth look.

Reese Witherspoon

Reese Witherspoon wowed audiences at the 2007 Golden Globes when she debuted a new do of long layers and asymmetrical bangs. More recently, she brought out another new style: she kept the bangs but lost the length, opting for a bob that accentuates her heart-shaped face. "Adapt layers to work with your face shape," says celebrity hairstylist Francky L'Official who has worked with Witherspoon. "The bangs elongate her heart-shape face and narrow her forehead."

Eva Longoria Parker

For years, Eva Longoria Parker's layered hair has complemented her feminine style, but when her Desperate Housewives character transformed for upcoming episodes, the actress followed suit. "This length is cut properly to shape her face in the perfect way," says L.A.-based hair stylist Robert Vetica. "It's layered and angled in the back and longer in front to give it dimension." This cut, which works best on straight or slightly wavy hair, can be blown-dry straight, or left loose and wavy for a more playful feel. For something more elegant, slick it back with strong gel.

Liv Tyler

When it was time for a change, Liv Tyler opted for a short, wavy coif, losing length and gaining even more sex appeal. "Her cut is extremely stylish and looks forever classy—this is a timeless look she can pull off at anytime," says N.Y.C.-based stylist Valery Joseph. "Most people don’t realize they can pull of a short, sassy cut like this." The trick to this one-layer style is, as always, having a stylist work with your face shape. Full, round face frames should opt for a longer version of the cut.

Jennifer Hudson

Jennifer Hudson's soft curls and short bangs were a fun style, but her chin-framing bob gave the Oscar winner a new attitude." The look is more sleek and sophisticated," says celebrity stylist Edward Tricomi. "She looks well put together and sexy." To achieve Hudson's look, "make sure the hair is cut around the shape of your face and your jawline," says Tricomi. Work pomade into the bangs and the ends to keep the look sleek.

Anne Hathaway

Anne Hathaway traded in her long, playful curls for a sleek and polished bob. "This cut is very sophisticated and really shows her glamorous side," says N.Y.C-based stylist Naomi Knights. "The length really frames the proportion of her face bringing into focus strong qualities like her lips and nose. By changing the layers, this cut can work on anybody," said Knights. If you have a long or round face, ask your stylist to adapt this to your face shape, either keeping it rounder and fuller (for long or narrow faces) or longer and straighter (to even out roundness).

Gwyneth Paltrow

Celebrity stylist David Babaii, who has worked with Gwyneth Paltrow, says her long style "created versatility and the opportunity to wear it many different ways.” When she wanted an update, she opted for a razor-sharp, shoulder-length style that's longer than the trendy bob yet very modern. "The bob is a classic but a lot depends on your face shape in selecting the length and angle," notes Babaii.
