The 22 Wildest Celebrity Hair Transformations of the Last Decade

In her immediate post-Girl Meets World days, Blanchard kept the look of a Disney Channel teen heroine, with straightforward, shoulder-length brown hair.

In 2019, Blanchard upped the ante with a more sophisticated, edgy style: a piecey, spiky short cut. According to her stylist, Laurie Heaps, Blanchard said the cut "actualized her identity."

For a time, Union's favorite hair look was her long, stylish braids, often twisted into a ponytail or pulled high atop her head.

Summer is always a good time to try out a new hairdo, and that's just what Union did, chopping off her long hair in favor of a deep side part and a chic, choppy bob.

As Stranger Things' resident pretty boy Steve Harrington, Keery's long hair was pretty much his signature look, both on and off screen.

Fans had a lot to say when Keery showed up at a Chanel event in September 2019 with his signature long hair cut off and sporting a choppy set of short bangs.

At the start of the 2010s, Hudgens was still a Disney star, complete with a youthful, ingenue look and loosely ringleted curls.

Hudgens grew up over the course of the decade, debuting this sleek and stylish bob in early 2018.

It's hard to think of a hairstyle more deeply associated with a character than Clarke's bleach-blond, flowing hair during her tenure as Daenerys Targaryen.

After wrapping Game of Thrones, Clarke took the plunge back to brunette with this sleek, retro, dark bob. It's part style choice, part necessity: she told Glamour that her GOT dye regimen nearly wrecked her hair. "Yes, it is quite short—because my hair was, like, dying!... I'm honestly trying to grow out the blond, because it's just killed my hair, and I miss having nice hair!"

Perry's early days as a pop star were marked with lots of hair color changes, but she was most often seen with black hair styled in waves and a simple center part.

By the time 2019 rolled around, Perry had cycled through tons of hair looks and settled on something totally different from before: a pale blond, perfectly piecey pixie cut! "Everything is more fun with short hair! I can just get up and go. I feel so liberated with this hair now," she revealed to W magazine back in 2017 when she first tried out the style.

During her stint as the stylish editor Kelsey on Younger, Duff has gone through several hairstyles, but none quite as bold as this pale blond, sleek and straight look.

With the reboot of Lizzie McGuire officially in the works, Duff delighted fans by returning to her (hair) roots with a loose, casual style with parted bangs and a honey-blond color. "I kind of have been itching for my Lizzie McGuire bangs for awhile," she admitted to Refinery29.

Part of Centineo's boy-next-door charm was definitely his tousled curly hair.

Where'd you go, Peter Kavinsky? Centineo surprised fans by showing up with a postfilming buzz cut.

Brown's short hair is such an iconic part of her Stranger Things character, Eleven, that we could hardly imagine her without a cute short cut.

While most celeb hair makeovers involve cutting off length, Brown went the opposite direction, with longer hair than we've ever seen on her!

The marvelous Mrs. Maisel herself took inspiration from her onscreen brunette persona with this simple, wavy style in a dark brown.

In 2019, Brosnahan broke out of her usual style with a gorgeous golden-blond color and long, smoothly styled hair.

Stenberg's hairstyles have changed a lot, but they've worn a lot of short styles, like this fun, curly look from 2018.

In a complete turnaround, Stenberg started rocking long, thick braids woven through with shades of aqua, teal, and dark blue. In 2018, they penned an essay for InStyle admitting the struggles they've had with their hair over the years and their eventual learning to love the process of changing it up. "Sometimes it'll be a more masculine look with little-boy curls, or I'll part it in the middle and slick it down to look more feminine. The best part: It's totally up to me."

Zendaya chopped off her Disney Channel curls in favor of this short, sleek, and spiky bob.

Zendaya looked like a total Disney princess with her long, wavy hair and unexpected — but gorgeous — deep red color. She's gone back to the color a few times but notably debuted it at a Spider-Man event in Summer 2019, apparently as a tribute to Mary Jane Watson, the comic-book inspiration for her character, MJ.

As Twilight came to an end, Stewart still sported Bella Swan's messy, neutral brown waves.

Stewart spent most of the decade experimenting with her style, often choosing edgy, spiky styles like this near-buzz cut in a silvery white.

In her early days as a new ingenue, Collins played it safe with sleek, straightforward dark hair.

Collins shook things up quite a bit with this bright, magenta color and a stylish, swingy chin-length cut.

The early 2010s were peak "princess" Swift, as she bridged the gap from sweet teenage sensation to grown-up star, and her elegant, girlie style reflected that.

Swift doesn't experiment with style much, but when she does, like with this choppy cut in 2016, it's unexpected and deeply cool.

After cutting her hair on screen in Les Misérables, Hathaway stepped out for several months with a swept pixie cut. The cute cut was something of a healing experience after her onscreen haircut left her in tears. "Cutting my hair reduced me to, like, mental patient-level crying. I was inconsolable," CinemaBlend quoted her as saying at the time. But it was worth it: she walked away from the deal with a brand-new style and a shiny Oscar!

Hathaway embraced her usual elegance with beautifully highlighted waves after years of shorter hair.

Cyrus spent a good chunk of the mid-2010s pushing the envelope musically and stylistically, like with this punky pixie cut.

With perfectly waved golden-blond hair, Cyrus shifted into a more classic style.

During her time playing Gwen Stacy in the Amazing Spider-Man franchise, Stone sported midlength light blond hair and full bangs.

Stone went back to her famous red hair, taking inspiration from Old Hollywood for her elegant, shiny waves.

Blair Waldorf would have been proud of Meester's effortlessly flowing curls.

We almost didn't recognize Meester with this choppier, piecier, and much blonder look, but she rocked it!

Knowles has always been a master of letting her natural curls fly free and styling them in unique ways, like this wild updo.

In 2018, Knowles made one of her biggest hair choices yet by cutting it short and dyeing it a pale blond.

Earlier in her career, Roberts sported long, brunette, wavy hair that reminded everyone of her connection to her famous aunt Julia.

Over the last several years, Roberts has tried out tons of hairstyles and hair colors, including this cool blond cut that landed just above her shoulders.

Luscious, dark hair was something of a Kardashian/Jenner family calling card, and Jenner was right in line with the trend.

Jenner began really forging her own style with this platinum-blond, blunt-cut bob.
