13 Celebs Who Chopped Off All Their Hair

After half a life spent with Hermione Granger hair, the first thing Emma Watson did when shooting wrapped on Deathly Hallows Part 2 was chop everything off. She's since decided to grow it out again, citing the greater flexibility associated with longer hair, but she pulled off the pixie look well while it lasted.

As Felicity, Keri Russell was known for her long curls. At the beginning of second season of the show, however, fans found that she'd ditched the long locks during the summer hiatus. While the short look framed Russell's face well, it unfortunately ruined Felicity's distinctive style. Whoops.

Heroes cheerleader Claire Bennet had straight blonde hair a mile long. These days, however, Hayden Panettiere does not.

Evan Rachel Wood has a tendency to change her hair every two minutes. She debuted her latest experiment at the Hollywood premiere of True Blood season 4. Opinions are divided: Sure, she looks cute, but she also looks significantly older than she is. Ah well; she'll probably start growing it out again tomorrow.

Zac Efron made his early career with a loveable floppy haircut every 13-year-old girl on the planet wanted to play with. After his High School Musical days were over, though, he said goodbye to the floppy hair and hello to shorter hair-- and hopefully a more adult career.

Ah, Britney. Who could forget the infamous Shaved Head Incident of 2007?

Post-Pirates of the Caribbean: The Curse of the Black Pearl, Keira Knightley was all over the map in her career choices. The one that surprised people, though, was her turn as real-life bounty hunter Domino Harvey in Domino, for which she cut off her enviable shiny locks. The film was a flop, but the haircut was a hit.

The first sign we all had that little Biebs was turning into an adult was his decision to rid himself of his trademark haircut. They just grow up so fast!

Carey Mulligan spent the early part of her career with long hair, but debuted a pixie cut in Wall Street: Money Never Sleeps. She got rid of the short hair at around the same time she got rid of Shia the Beef.

Spike's trademark bleached blond style on Buffy the Vampire Slayer was a matter of necessity: James Marsters' natural hair color was deemed too similar to David Boreanaz's, so the hair and makeup department bleached it to see what would happen. After bleaching his hair continuously for seven years, Marsters finally shaved it all off after the conclusion of Angel as a charity stunt.

Natalie Portman was a super method actor way before Black Swan: She went all out and shaved her head for V for Vendetta in 2006. Now that's dedication.

Sawyer's long hair may have looked hot, but according to Lost actor Josh Holloway, it was also really annoying. Presumably he is no longer annoyed.

The former Joey Potter chopped off all her hair shortly after her somewhat surprising marriage to Tom Cruise. Maybe she was trying to make the situation seem less like creepy cradle robbing.
