These 6 Hollywood Blondes Once Went Brunette – Photos That Made Fans Think They Looked Better with Dark Hair

For decades, blonde hair has been part of the public image for some of Hollywood’s biggest stars. But every now and then, a dramatic brunette transformation changes the conversation entirely — and fans often end up wondering whether the darker look suited them even better.

Paris Hilton sparked exactly that reaction last weekend when she stepped onto a runway in deep brown hair, leaving fans doing a double-take. But she is far from the only celebrity blonde to shock audiences by going dark.

Paris Hilton

On May 17, 2026, the "Come Alive" singer, 45, walked the Gucci Cruise 2027 runway in a yellow-and-gold puff-sleeved dress, black boots, and a fur coat, carrying a red handbag and sporting deep brown hair with side bangs.

Watching from the audience were Lindsay Lohan, Shawn Mendes, Mariah Carey, and Kim Kardashian.

For someone who has made platinum blonde as much a part of her identity as her famous catchphrase, the transformation was the last thing anyone expected. And fans had plenty to say about it.

"I always thought she'd look better brunette. This just proves it," one fan wrote, another adding, "Loving the dark hair!" A third kept it simple, "That's iconic."

Cameron Diaz

Cameron Diaz stepped away from acting for over a decade before making her return, and her upcoming romantic comedy for Amazon MGM Studios has put her firmly back in the spotlight.

But for many fans, a single photograph from 2006 still says everything. Diaz, who built her career on films including "Charlie's Angels" and "There's Something About Mary," wore dark hair that year, and the memory of it has never quite faded.

"This is one of the most beautiful pictures of a woman I have ever seen. I prefer her as a brunette," one fan wrote, while another added, "She looks better with dark hair."

A third did not mince their words, "Wow she really looks amazing I think that she looks better this way."

Cate Blanchett

When Cate Blanchett arrived at the 2019 BAFTAs in custom Christopher Kane and chestnut brown hair, the world barely recognized her.

The transformation was done for a role at the National Theatre, confirmed by her makeup artist Morag Ross, and styled into a simple side parting by her long-term colorist, Nicola Clarke, of John Frieda in London.

Since shaving her head for a role in 2000, Blanchett, who was 49 at the time, had worked through various shades of blonde, from strawberry to cream, with one brief pink period. The brunette, by most accounts, suited her just as well, and fans did not hold back.

"Cate Blanchett with dark hair supremacy," one wrote. Another said, "Cate Blanchett with dark hair has an effect on me," while a third added, "Cate blanchett with dark hair so true.[sic]"

Reese Witherspoon

Reese Witherspoon’s blonde hair has long been part of her classic Hollywood image, which made her brunette era unexpectedly striking for fans revisiting old photos.

A comparison image of Witherspoon, showing her earlier brunette look alongside her current signature blonde, drew one of the most specific fan reactions on this list. The two photographs, placed side by side, set off a warm conversation about which version fans preferred.

“At first glance, I thought the brunette was a young Sally Fields, [sic]” one viewer noted. Another wrote, “Reese always looks great, but I love her brunette look more.”

A third simply added, “Brunette look better on her. [sic]" while a fourth agreed, “She looks great as a blonde, of course, but I really like the brunette even better.”

Margot Robbie

Margot Robbie debuted brunette hair at the 2014 Oscars, fresh from her breakthrough in "The Wolf of Wall Street," pairing the new color with dark brows, smoky shadow, and purple lips. Fan reaction was more divided than any other entry on this list.

"Honestly the brown suits her much better (but she's beautiful no matter what)," one fan wrote. "Even more beautiful SOME users didn't like her look [sic]," another wrote.

"It's still Margot Robbie, but I agree with the point you're making, it doesn't seem to suit her very well, at least not this dark," one commenter shared.

The opposing reaction was equally memorable, with another social media user joking, "Margot Robbie as a brunette is just as TERRIFYING as you probably imagined."

Blake Lively

In January 2023, Blake Lively, 35, posted a selfie to her Instagram Stories with her honey blonde hair transformed into a warm auburn, a long barrel curl over one shoulder, and a soft-glow filter over the whole image.

She added no caption and offered no explanation. The post coincided with news that she had been cast in the film adaptation of Colleen Hoover's novel "It Ends With Us" opposite Justin Baldoni.

Fans were not waiting for an answer. "Brunette hair really makes Blake Lively's ethereal face card stand out 🤌❣️," one wrote, a second adding, "Beautiful and gorgeous."

And while not every brunette transformation won unanimous approval, the reactions made one thing clear: when some of Hollywood’s most famous blondes switch things up, fans immediately start debating whether they should ever go back.
