“At first it was fun,” she told the outlet. “I was really excited for the blonde era — like, Blonde Billie is gonna be so cool. But it did not go how I wanted it to go.”

The Golden Globe winner went on to explain that she felt lost in her new look (although a throwback Instagram post shared last December proves she’s a natural blonde).

“I completely had no idea who I was,” she shared. “I came up with this whole aesthetic, and I just got swallowed up into it.”

And even when she ditched her lighter hair color in exchange for a dark chocolatey shade closer to her signature black, she still didn’t feel completely herself.

“I look back at that and I’m like, ‘Who is this brunette?’” she said. “A brunette! That wasn’t me.”

Eilish went to great lengths to get her hair as blonde as it was.

At the time, she gave a run-down on Instagram of what went into the hair dying process, which took multiple rounds over the course of a six week period and involved a cover-up wig for her performance at the 2021 Grammys.

Despite what seemed to be a regrettable beauty decision, the seven-time Grammy winner did return to her blonde hair to channel vintage Barbie for the “What Was I Made For?” music video — albeit with a full stash of wigs on hand. “It was a full-on wig city,” she said.

She even committed to the costume by spending two hours in the glam chair as stylist Ben Mohapi worked the hairpiece into a ponytail.

So what color does she feel best with right now?

Over the summer she returned to her edgy style roots, with a black style accented with a fiery red color extending from her roots to her bangs in an ombré effect.

The look has made an appearance on the Lollapalooza stage, where Eilish performed this past August, and most recently the 2023 LACMA Art+Film Gala, where she showcased her bold ‘do with an all-black outfit topped with a head scarf.
