Michelle Monaghan is back to blonde—and very blonde at that!

The True Detective actress, 38, celebrated the opening of the Academy’s Hollywood Costume exhibit in one of her blondest looks to date—but it took her more than one trip to the salon to get her there!

The usually brunette beauty first flaunted honey-hued strands back at the 66th Primetime Emmy Awards on Aug. 25. The fair locks popped against her white Giambattista Valli dress.

But then, on Sept. 11, the Best of Me actress, clad in fuchsia, screened Fort Bliss in Los Angeles, and her blonde hair had been transformed into an ombre, with chocolate roots that slowly faded into a dirty blonde color at the ends.

The next week, on Sept. 18, Monaghan visited the SiriusXM’s New York City studio in a navy blue top, and already her hair appeared to have more highlights from the chin down, brightening up her entire look.

More salon time! By Sept. 27, while walking the red carpet at the San Diego Film Festival 2014, the former fashion model posed in a leather turquoise dress and her latest ‘do! For this appearance, Monaghan seemed to have lightened up her roots to match the ends, ditching the ombre in favor of an all-over golden tone.

But she would go lighter still: At the Academy of Motion Picture Arts and Sciences’ event, Monaghan’s stylist simply added more highlights, some as light as platinum and others as deep as gold, to create one of her lightest, brightest looks to date. The star, who was dressed in a Dolce & Gabbana dress with a bold key print, even had her eyebrows lightened, giving her the sun-kissed appearance of a true California blonde.
