Millie Bobby Brown Just Went from Brunette to Blonde

Millie Bobby Brown just entered her blonde bombshell era—and we’re absolutely here for it. 

The Stranger Things star just debuted a honey blonde makeover, and it’s giving peak Y2K energy. With that effortlessly sun-kissed, golden glow, Millie’s new ‘do is basically a reinvention of Britney Spears’ Oops!… I Did It Again era style. This isn’t just any blonde, either—it’s warm, rich and full of dimension, making it the perfect shade to channel that early-2000s pop star fantasy. With the resurgence of all things Y2K—see: low-rise jeans, frosted lips, and butterfly clips—it was only a matter of time before the quintessential blonde of the era made a comeback.

Honey blonde is the perfect middle ground between icy platinum and deep caramel, making it ultra-flattering on a wide range of skin tones, says Renée Valerie, Director at R+COLOR Education and R+COLOR Collective Member. Plus, it has that soft, lived-in feel that makes it look effortlessly natural, so it’s easy to use as a transitional shade as we embrace warmer weather in the weeks ahead. Unlike the cool-toned, high-maintenance blondes of past seasons, this shade is all about warmth and radiance.

Whether you’re fully embracing the Y2K aesthetic or just want a low-maintenance blonde that still looks fresh and expensive, honey blonde is the move. Add in some tousled waves and a little lip gloss, and you’re basically ready to headline the TRL countdown.

How to Get the Look

For natural blondes, achieving this look is as simple as adding warm, golden lowlights and a gloss to create that rich, dimensional effect—think buttery tones over anything too cool or ashy. Valerie likes to start the process by adding that warm hue all over and then going in with dimensional highlights to round out the look.

Brunettes, on the other hand, may need some strategic balayage or babylights to lift the color while keeping the roots soft and blended for a natural grow-out. Make sure to ask your stylist for a warm, golden blonde with caramel or honey undertones, avoiding anything too platinum or brassy. And if you want to go full Y2K, consider pairing it with face-framing highlights to really bring out that early-2000s pop princess energy.

How to Maintain the Look

Millie Bobby Brown is no stranger to major hair transformations—she’s rocked everything from a buzz cut to deep brunette and now this dreamy honey blonde. But with great color comes great responsibility, and keeping this golden hue fresh requires some dedication. 

To maintain that rich, sun-kissed glow, swap in a sulfate-free, color-safe shampoo and a hydrating conditioner to keep strands nourished. Since blonde shades—especially warm tones—can fade or turn brassy over time, a weekly gloss treatment or purple-tinted conditioner (used sparingly) can help keep things balanced.
