24 Extreme Hair Makeovers

01 of 24

Natalie Dormer

The Game of Thrones star unveiled her head-turning new look, which she got in preparation to play Cressida in The Hunger Games: Mockingjay, at the 2014 SAG Awards on Jan. 18. ''[Cressida] comes from the Capitol, so she's got a stylized thing going on and now she's turned rebel,'' said Dormer. ''I think it's right for the character.'' —Bronwyn Barnes

Jennifer Lawrence

Now that America's BFF has chopped off all her hair, trend spotters might just see an upswing of pixie cuts this holiday season. The dramatic new 'do — in addition to losing inches, she also lightened the color — wasn't for a movie role. Instead, Lawrence jokingly announced, ''I just did it to make Francis [Lawrence, Hunger Games: Catching Fire director] mad!'' before clarifying that, really, her hair was just fried from all the brunette dye jobs she had to undergo to play heroine Katniss Everdeen. The arena has nothing on the painful realities of hair care. —Erin Strecker

Jennifer Hudson

Putting the ''Spotlight'' on a chic new coiffure, the triple threat came thisclose to sporting a shorn dome to match her Oscar. —Lanford Beard

Beyoncé

Were fans ''Crazy in Love'' with Mrs. Carter's decision to let stylist Neal Farinah chop off her signature windblown tendrils in favor of a punky pixie? That'd be a resounding ''YES!'' according to the million-plus likes the R&B diva garnered on a series of three Aug. 8, 2013, Instagram pics. —Lanford Beard

Anne Hathaway

Going under the shears ''reduced me to, like, mental-patient-level crying,'' Anne Hathaway told Kelly Ripa of shaving her head to play Fantine in Les Misérables. Apparently, a $10 million paycheck is hollow succor to an actress who is bereft of hair. —Bronwyn Barnes

Charlize Theron

We can't be mad at the Oscar winner for going back to her roots with the sheared-and-chic look she adopted for 2013's Mad Max: Fury Road. —Lanford Beard

Rihanna

After the songstress chopped off her oft-changing tresses in favor of this Caesar cut, it's safe to say she'll be able to walk around under a much smaller umbrella-ella-ella-eh. —Lanford Beard

Lena Dunham

The Girls star debuted a boyish look at New York Fashion Week in September 2012. How did she have the courage to try something this bold and different? All adventurous women do. —Lanford Beard

Elisabeth Moss

Is that Peggy Olson or Twiggy? The Mad Men star showed off a lighter, shorter style at the New York premiere of For a Good Time, Call. Do blondes really have more fun? They do when their super-sleek short 'do cuts an hour off primping time. —Lanford Beard

Miley Cyrus

After documenting her new 'do on social media, Cyrus got defensive when the inevitable backlash began. ''My dad @billyraycyrus used to tell me ''opinions are like a--holes every body has one. LOVE my hair feel so happy, pretty, and free,'' the singer-turned-actress tweeted. —Bronwyn Barnes

Britney Spears

In February 2007, the pop starlet paid a late-night visit to Esther's Haircutting Studio in Tarzana, Calif., where she seized a pair of clippers and proceeded to shave her own head. According to salon owner Esther Tognozzi, Spears then became emotional, declaring, ''My mom is going to freak.'' —Bronwyn Barnes

Scarlett Johansson

Before hitting the road to promote Lost in Translation in 2003, Johansson debuted a '70s shag at New York Fashion Week. The actress described the style as a Florence Henderson-inspired mullet, but gave off more of a Ziggy Stardust ''screwed down hairdo'' vibe. —Bronwyn Barnes

Evan Rachel Wood

Another Bowie homage came courtesy of the True Blood star, whose androgynous coiffure balanced out her generally feminine aesthetic. ''I think I'm a little controversial,'' she told E! Online. ''I just try and keep some mystery, so hopefully people can't really put their finger on it.'' —Lanford Beard

15 of 24

Demi Moore

Critics panned her performance as a female commando in 1997's G.I. Jane, but at least a newly buff Moore (in more ways than one) managed to pull off the cue ball look in real life. —Bronwyn Barnes

16 of 24

Emma Watson

After more than a decade of follicular association with the long locks of Hermione Granger (whose own locks went from frizzy to fab in the seven Harry Potter films), Watson was ready for a drastic change of pace as she transitioned to a more grown-up film career — and a more sophisticated aesthetic. —Lanford Beard

Jennifer Aniston

Oh, Rachel Green, why hast thou forsaken us? The Friends star celebrated her marriage to Brad Pitt by chopping off her long layers in December 2000. —Bronwyn Barnes

18 of 24

Katie Holmes

Couture fashion shows in Paris, double dates with then-husband Tom Cruise and David and Victoria...in the summer of 2007, Katie Holmes had clearly fallen under the influence of the crossover Brit formerly known as Posh Spice. So much so that celebrity hair-watchers (yes, there is such a thing) wondered if her angular bob was a copycat cut. —Bronwyn Barnes

19 of 24

Michelle Williams

After making waves with a shoulder-length girl-next-door look since breaking out on Dawson's Creek in 1998, Williams changed it up in late 2010 with a style dedicated to her late partner — and the father of her daughter, Matilda — Heath Ledger. ''I cut it for the one straight man who has ever liked short hair and I wear it in memorial of somebody who really loved it,'' she said. —Lanford Beard

Viola Davis

Davis spent much of the 2012 awards season donning hair pieces to events. When Oscar night finally arrived, The Help's Best Actress nominee said her husband encouraged her to go au naturel. ''It gives me flavor. It makes me feel like I'm spicing up my life a bit,'' she told People magazine. —Lanford Beard

21 of 24

Halle Berry

The versatile actress abandoned her pageant queen look and has rocked a close-cropped look for much of her career, proving that a boyish cut doesn't mean one can't still gets men's heads turning. Appropriately, she wore this spunky style on Spike TV's ''Guys Choice Awards'' carpet back in 2009. —Lanford Beard

22 of 24

Natalie Portman

Portman may have picked up an English accent for 2005's V for Vendetta, but she also lost a whole lot of hair. Living on the razor's edge, Portman and director James McTeigue took a gamble as they filmed her head-shaving scene in a single take. —Lanford Beard

23 of 24

Ginnifer Goodwin

Method acting be damned, the former Big Love star was so enamored of her own pixie cut, she confirmed to InStyle, that she begin to insist on a wig clause in all her contracts so she could express herself through her hair off-set. —Lanford Beard

24 of 24

Keri Russell

When ratings for the sophomore season of Felicity took a nosedive in 1999, network execs made Russell's new super-short hairstyle the scapegoat. ''It must have been a boring year to have so many people worried about my hair,'' the actress told the New York Times in 2004. —Bronwyn Barnes
