Julianne Moore just distilled every major hair trend of summer 2025 into one effortlessly chic haircut.

The star debuted her new look at Netflix’s global premiere of Sirens in New York City. Enter: The blunt bob. Moore has said goodbye to her signature long lengths to officially join Team Bob like this rest of the world of celebrity. Though Nicole Kidman’s Met Gala crop was a fake-out, everyone from Keke Palme to Millie Bobby Brown have chopped their hair.

The Sirens star’s new look was crafted by Orlando Pita, the hairstylist you’ll find getting the likes of Selena Gomez and Anne Hathaway red carpet ready, and coiffing Gigi Hadid’s bob for the cover of Vogue. It complemented the elegant styling by Moore’s go-to stylist Kate Young, who fitted her in an elegant Bottega Veneta black gown.

Sleek, polished, and timeless, Moore’s new hairstyle is the ultimate power cut for women over 60—the experts agree.

“The blunt bob is a sharp, straight-across style with no layers—it flatters nearly every face shape,” explains Juandiegoteo, hair designer and Redken ambassador. “It’s especially ideal for fine hair because it creates the illusion of volume. Plus, it’s incredibly low-maintenance, air-dries beautifully, and can be tailored in both length and shape to suit your features.”

When it comes to color, Javier Mateo, co-founder of THE LAB Beauty Studio, predicts a summer dominated by rich, radiant tones. “Think copper, amber, and fiery orange—shades that feel bold yet warm, and pair perfectly with sunlit skin,” he shared in a recent trend forecast.

Julianne Moore is the summer beauty muse we didn’t know we needed.
