Throughout the '90s, Julia Roberts tried a wide variety of hairstyles. The actor stunned fans in 1991 when she went to the Oscars with a bleached blonde bob, characteristic of Marilyn Monroe, via Refinery29. As told by W Magazine, she came back with another surprise in 1995 when she opted for a shoulder-length, straight, and lightly-layered cut featuring side-swept front bangs. Only a few years later, she changed up her style again at the premiere of the film "Red Corner" in New York City. This time, Roberts had a silvery-golden bob with soft curls at the bottom and full bangs.

In the late nineties, Roberts grew out her hair and returned to a much darker hair shade, per W Magazine. At the 2001 Academy Awards, during which she won an Oscar for Best Actress in "Erin Brokovich," Roberts had her dark tresses styled in a straight, sleek updo, via Vanity Fair. In the 2000s, however, Refinery29 reports that she decided to lighten her strands to a strawberry blonde tone, which seems to have become her favorite over the years. Nowadays, the actor typically opts for a middle part and beachy waves, per Headcurve. Though Roberts changes her style slightly from time to time, nothing compares to the drastic hair shifts that mark her early career.
