Most Popular Celebrity Hairstyles

Top stars change their look for the cameras almost as often as they change their shoes. But we tend to remember that one perfect coif or standout cut most. Here are few celebrity-looks from demure to daring that stylists across the country are (still) asked to duplicate.

Jessica Simpson This blond bombshell never has a hair out of place -- maybe it's because Jessica Simpson's best friend is her stylist, Ken Pavés. Fans can re-create her looks without changing their locks now that she and Pavés have created a line of Jessica-inspired wigs at hairuwear.com.

Sarah Jessica Parker Now that she's a mommy in the city, Sarah Jessica Parker proves that cascading curls don't have to be prim and proper. For this easygoing 'do, scrunch a dab of alcohol-free gel into wet locks, then air-dry. Try Herbal Essences Totally Twisted Curl Scrunching Gel ($4, drugstores).

Demi Moore It may have taken several years for Demi Moore's hair to reach great lengths (remember that G.I. Jane crew cut?), but she's basking in the glow of her shiny tresses now. The best way to boost luster: After styling, spritz on a shine spray like Redken Vinyl Glam.

Jennifer Aniston Though she now wears her hair long and straight, Aniston is best known for The Rachel, a medium-length layered look named after the character she played on Friends.

Farrah Fawcett The feathered locks Farrah Fawcett made famous on the hit '70s show Charlie's Angels are more modern than ever. Even other celebrities (like Beyoncé in 2006) are stealing this sexy, full-bodied style.

Paris Hilton Since she is stalked by the paparazzi, Paris Hilton's long, side-swept bangs are constantly in the spotlight. Brushed to one side, slightly curled under, worn straight across, or pinned back -- this is one versatile fringe.

Debra Messing Full, wavy tresses are all the more stunning with Debra Messing's fiery red locks. Tip: To get weightless volume, use a dollop of mousse, such as Dove Pro-Age Styling Foam ($5, drugstores), at the roots before blow-drying. Use a wide-barrel curling iron for those large curls.

Teri Hatcher A deep side part like Teri Hatcher's is flattering on all face shapes. And it's especially great for offsetting disproportionate features, like a big nose or close-set eyes. (Not that we're saying Teri Hatcher is imperfect!)

Halle Berry Although she's gorgeous with any length hair, Halle Berry's short, sexy look from 2001 is still a style favorite. And since a close crop is virtually wash and go, it's perfect whether you're a movie star or supermom.

Ashley Judd Parted to the side and smoothed back, Ashley Judd's half-up do from 2006 is reminiscent of a Greek goddess. Gather hair back with a sparkly clip for dressy events or with a simple ponytail holder when you just want to kick back and relax.
