12 Celebrity Haircuts That Made a Career

Lesley Hornby-better known as Twiggy-went from pretty teen model to the international symbol of sexy '60s androgyny with a few quick snips of the scissors.

Miley Cyrus surprised all of us by trading her lengthy Hannah Montana strands for a platinum pixie, and with her new 'do also came edgier style choices. “It’s crazy because every day, your hair is different when it’s short,” she told us. “Every day I wake up, and I get something new. So it’s fun!”

Let's be honest: Audrey Hepburn was flawless in any hairstyle. But something about her closely shorn crop made her birdlike features and milky white skin all the more irresistible to America, and the Academy, earning her an Oscar for Roman Holiday in 1953.

A slimming red suit and effortlessly feathered waves? It's no wonder Farrah Fawcett's 1976 poster has sold over twelve million copies to date.

There was just something so lovably right about Meg Ryan's shag, it's hard to imagine late '90s blockbusters like City of Angels and You've Got Mail without it.

The star recently told Allure magazine the cut was "the ugliest haircut [she'd] ever seen." Needless to say, America did not agree. (It is still one of the most requested styles at salons across the country.)

If you're known for your ultra-long glossy black tresses, what's a good way to make waves? By shaving them off, of course, like Demi Moore did in 1996 for her role in G.I. Jane. The movie earned lackluster reviews, but Moore's gutsy move was a universal thumbs up.

A sharp angular bob took Posh Spice from a UK singing sensation to a stateside fashion icon.

In 2007, Rihanna kissed her Bajan braids goodbye-and said hello to a worldwide number one hit "Umbrella." Four Grammy Awards later, and the hair chameleon is still keeping her look fresh.

The ultimate girl next door turned Hollywood hot with heavy bangs and angled ends.

After her split with Ryan Phillipe in 2007, the star's breakover bangs turned heads at the Oscars, earning her a slew of leading lady roles-and an Avon contract.

With her overgrown Hogwarts hair, she played the brainy and beautiful Hermione in the Harry Potter series. But by chopping it all off in 2010, she promptly caught the attention of the fashion elite, appearing in Burberry ads and signing a Lancome contract.
