Margot Robbie's Natural Hair Color May Surprise You

Margot Robbie was the perfect choice to play the titular role in the hugely successful "Barbie" movie. But we have surprising news about the poster girl for bombshell blond locks — she's a natural brunette. Jimmy Kimmel exposed her natural hair color on "Jimmy Kimmel Live" in 2016 when he shared a throwback photo of the "I, Tonya" star looking unrecognizable aged 13, wearing glasses and braces. The young teen was reading "Harry Potter and the Order of the Phoenix" with her dark brown hair in a ponytail. "I was really into slicking my hair back," Robbie said. "God knows why."

Although we'd love to see Robbie take more fashion risks, she's taken plenty in the hair department. Before finding fame and making blond her trademark shade, she colored her hair even darker. "I always dyed it dark in high school. I was devastated when I had to go blond," she told Elle, but admitted she eventually came round to light locks. "Once I was blond for a couple of years, I ended up loving it. But I don't have a preference. I like both," the Australian actor star. She told InStyle the initially ditched brunette as a career movie. "I had brunette hair actually all through high school ... When I started working and acting, they all wanted me to have blond hair," she said.

Going from brunette to blond isn't easy (ask Gwen Stefani, whose natural hair isn't platinum blond, either), as the constant dying can result in the tell-tale signs of hair damage becoming increasingly obvious. And, unfortunately, Margot Robbie's natural tresses have taken the brunt of her changing shades.

"I've got really s**t hair so it's kind of hard to do my hair well. I really need a hairstylist to do my hair if it's going to look good. I have like three hairs left on my head," she told Harper's Bazaar, explaining she wears extensions to make her mane appear fuller. "People are always like, 'How do you have such healthy hair?' I'm like, 'I don't.' My hair is snapped off, it's s**t, it's gone, but hairstylists have suitcases full of fake hair and they make it look amazing," she added.

The actor also has a few secret weapon hair products. She told Marie Claire U.K. she uses Klorane Dry Shampoo Powder to keep her tresses looking fresh and make her brunette regrowth less obvious. "It's really good for adding texture and also helps disguise dark roots too," she said. To bring some moisture back to Robbie's hair, her hairstylist Halley Brisker used Olaplex No. 6 Bond Smoother Treatment while getting her ready for the 2024 Golden Globes. He explained it helped the "Bombshell" actor's hair look more luminous. "[It looked] lit from within," he said (via InStyle).
