Margot Robbie may look like a real-life Barbie doll [1] with her long blonde hair — her role in the "Barbie" film only drives that comparison home — but you may be surprised to learn her natural hair colour. Though she's been blonde for most of her major motion pictures — "The Wolf of Wall Street," "Suicide Squad," "Amsterdam," and "I, Tonya," for example — the actor's original hair colour is a much darker shade. In fact, Robbie's natural hair colour is brown.

If you look at old red carpet images of Robbie, you can occasionally find her wearing a hue that's closer to her natural colour, but she's spent the majority of her career as a blonde. "I always dyed it dark in high school," she told Elle magazine in a 2014 interview [2]. "I was devastated when I had to go blonde." It didn't take too long for her to get used to it though, and now, she embraces the light colour. "Once I was blonde for a couple of years, I ended up loving it. But I don't have a preference. I like both."

Occasionally you can find her switching behind the two colours. For example, at the 2014 Oscars, Robbie's hair was an ultra-dark, rich-brown colour. She wore a similar shade for her role as Valerie Voze in "Amsterdam," [3] but that was courtesy of some amazing wig. Now, she's in full Barbie mode with her shiny, bright blonde on full display.

Ahead, take a look at Robbie's hair colour transformation over the years.
