After her breakout role as Cassie in Euphoria, 27-year-old Sydney Sweeney has become one of Hollywood’s most in-demand actresses, as well as a Gen Z style icon. She only made her red carpet debut in 2017, but has already experimented with an impressive range of looks—and her hair has played no small part in her transformations.

“I’ve always felt that my hair represents just how I’m feeling and who I am at that time. It’s like an accessory to whatever you want to wear—the personality that you want to have that day. I think that people forget that it’s not just makeup. Your hair can actually transform you too.”1

Over the past few years, she’s dyed it every shade from platinum to strawberry blonde, but naturally, it’s “a mixture of brunette during the fall with a little bit of a red tint to it.” It’s also volume-challenged—she “grew up always wanting [curly and thick] hair”—so she relies on both heat tools and hair extensions to transform its texture.1

But for 2024, Sydney is on a “hair health journey.” In January, she became a global ambassador for the luxury haircare brand Kérastase. Then, after admitting that her hair was “fried” from all the dyeing and styling, she chopped it off into a bob... only to emerge with long hair extensions a few months later.
