“The intention was to keep Millie’s hair feeling effortlessly undone—as though she could have swept it up herself,” Burkill tells Vogue. “There’s a natural ease to the shape, with a soft, face-framing texture that complements the gown’s clean neckline.” Burkill used The Smooth Company Hair Wand to keep flyaways at bay and maintain a refined yet relaxed finish.

“Throughout this press tour, we’ve been leaning into a more lived-in, timeless aesthetic,” shares Burkill, “something fresh, understated, and quietly confident—and this first premiere look really captures that spirit: elevated, but never overworked.”

“The red is something we’ve wanted to explore for a while,” says Burkill. They created a temporary vivid gloss by mixing Goldwell Elumen Red with Millie’s own brand Florence By Mills’s Mane Character Vibes Hair Mask. “It gave us the perfect balance of richness, shine, and playfulness for the night.”

Burkill is a longtime member of the MBB glam team, while also styling the likes of Anna Kendrick, Lauren Sanchez Bezos, Katy Perry, and Kim Kardashian.

The Stranger Things and Enola Holmes actor debuted her bleach-blonde hair back in February, when she swapped her signature mid-brown for a Britney-esque shade–speedily executed by Hershesons’s colorist Veronica Wysocka. (She shared that the process from brunette to blonde was done in 12 hours). Across several months of press appearances and red carpets, Millie and Burkill experimented with bombshell waves, elegant up-dos, and a set of zany, ’90s-coded space buns. Her shade change also paralleled a distinctive style shift, as she donned noughties-era archival Hervé Léger and skintight LBDs, quadruple leopard print, and strong, feminine silhouetted gowns. As a blonde, MBB was having a lot of fun. And while she’s experimented with waist-length locks and a choppy little bob, Millie has since made a more permanent return to a light brunette.
