Are you a brunette contemplating a blonde leap? Or vice versa? Well, look no further. We've tracked down the best celebrity blonde and brunette transformations over the years. Ahead, see who made the switch to the dark (hair) side and served up some seriously stunning red carpet looks.
Allison Williams
After Allison Williams said farewell to playing Marnie on Girls, the actress lightened up her naturally-brown hair. However, she's since returned to her roots.
Bella Hadid
Supermodel Bella Hadid lived out every girl's hair fantasy by going blonde over the summer. The natural brunette embraced the color change and posted a snap on Instagram (opens in new tab) to prove it.
Kim Kardashian
The reality star turned heads when she first went blonde in 2015. Since then, she's often played around with her hair color, ditching her signature raven hair for dusty grey, platinum blonde, and even pink.
Blake Lively
Over the years, Blake Lively has switched up her signature blonde hair—including for the Green Lantern movie, where she met her future husband, Ryan Reynolds. But it was the actress' dark ombré look from 2018 that caught our attention.
Cara Delevingne
Though we think model Cara Delevingne looks great with any hair color, she's settled on a platinum blonde pixie cut.
Kendall Jenner
Kendall Jenner went blonde for the first time back in 2015 for a Balmain fashion show. She must've liked it, considering she switched up her dark hair once again this summer (opens in new tab).
Leighton Meester
We can't imagine Blair Waldorf from Gossip Girl with anything but dark brown hair, and neither could the show's producers, which is why Meester dyed her naturally-blonde hair brunette for the role (opens in new tab). The actress went back to her roots in 2018.
Shailene Woodley
Whether she's a bright blonde or a dark brunette, one thing is for sure: Shailene Woodley knows how to rock the low pony look.
Sofia Richie
Sofia Richie made a splash at the Cannes Film Festival when she debuted chocolate brown hair, a far stray from her usual dirty blonde color.
Lucy Hale
Lucy Hale stayed true to her trusty bob and kept her roots dark when she played around with a blonder look in 2019.
Sarah Jessica Parker
Since her days of sporting Carrie Bradshaw's blonde curls, SJP has stayed blonde for the most part, only venturing out on specific occasions like the 2006 Met Gala.
Margot Robbie
Margot Robbie's hair is naturally blonde so she turned heads when she arrived at the 2014 Academy Awards with dark brown for her role in Z for Zachariah.
Cameron Diaz
Although Cameron Diaz is known for her bright blonde waves, in 2006 the actress went brunette while promoting The Holiday.
Lindsay Lohan
Back in 2005, it felt like Lindsay Lohan had a new hair color every week. Whether she was her classic red, a beach blonde, or dark brown, you never knew what the actress would show up rocking.
Sienna Miller
Sienna Miller forwent her typical platinum blonde tousle in 2004 for an edgy chocolate brunette color—and we're still here for it.
Nicole Richie
The California girl usually favors beachy blonde, but has also tried on darker shades—as well as silvery white at the Met Gala (opens in new tab).
Rachel McAdams
The actress' signature sunny hue suits her to a T, but we love the way (opens in new tab) this chocolate shade makes her eyes pop.
Biel has gone with (opens in new tab) a sun-kissed shade in the past (opens in new tab), but this espresso hue really sets off her creamy complexion.
Miley Cyrus
We'd be remiss to omit Miss Miley, who's not only played with her hair color, but also her hair lengths.
Jessica Alba
Alba was one of the forerunners of the ombre hair trend, but her single-toned brown hue is just as lustworthy (opens in new tab).
Emma Watson
Watson drew major attention when she debuted a pixie cut, but has also played around (opens in new tab) with her color.
Scarlett Johansson
She's best known (opens in new tab) as a bombshell blonde, but the actress still turned heads as a warm brunette.
Dakota Fanning
Fanning embodied her vampire role in The Twilight Saga films with chilling acting chops—and darker strands.
Claire Danes
The Homeland star (opens in new tab) has admitted that after switching between blonde, brunette, and red so many times, she no longer knows what her natural hair color is.
Charlize Theron
Though she's stepped out with both champagne and raven-colored hair, Theron made beauty headlines when she decided to shave it all off.
Jennifer Lawrence
For actresses, making big beauty changes is often just part of the job. In Lawrence's case, playing Katniss Everdeen (opens in new tab) required a darker hue.
Beyoncé
Queen B loves to play with her hair, including lighter locks and a few fun haircuts.
Rihanna
RiRi certainly keeps us on our toes—not only for her chic hairstyles, but for how frequently she changes them up.
Zooey Deschanel
These days, the New Girl actress sticks to an eye-popping dark brown, but we can't forget her time as a sweet blonde.
Jessica Stam
We're used to seeing the model as a blonde, but her near-black shade made a major statement.
Elizabeth Olsen
This actress typically sticks to a sun-kissed tone, but has tried being a brunette as well.
Ashley Greene
Ashley Greene saw the light and changed up her usually chestnut locks.
Emma Stone
Stone—while best known (opens in new tab) for her red hair—is actually a natural blonde, which she embraced for her role as Gwen Stacy in The Amazing Spider-Man series.
Drew Barrymore
The actress (opens in new tab) has tried so many different hues, but our favorites include a golden blonde and this auburn shade.
Carey Mulligan
The actress is most often rocking a blonde or platinum crop, but she changed it up with dark brown a few years back.
Leigh Lezark
The DJ (and one of our favorite It girls) looks striking at both ends of the color spectrum.
Miranda Kerr
The supermodel (opens in new tab) usually sticks to her chocolate hair, but also looks stunning as a blonde.
Natalia Vodianova
The supermodel plays up her classic beauty with a subtle change in hair color—from light, golden brown to dark blonde.
Emma Roberts
Roberts' change was less dramatic, as she ventured from caramel brown to dirty blonde.
Anne Hathaway
Hathaway only strayed from her deep brown very briefly, but the platinum color she chose had everyone buzzing (opens in new tab).
