The 19-year-old made waves earlier this year when she debuted a blonde chopped style, a departure from the dark hair with neon green roots that she'd become known for.

In fact, the hair reveal caught so much attention that the picture posted on Instagram received a million likes in just six minutes, breaking the previous record held by Selena Gomez.

And that same picture is now Billie's most liked on the platform, with more than 23 million likes in total. It's the sixth-most-liked Instagram photo of all time.

But in a surprise post on Thursday, Billie revealed that she'd gone back to dark hair, simply captioning the photo: "Miss me?"

The picture has picked up nearly 10 million likes in just 14 hours.

Billie's hair transformation comes after the release of her fifth yearly interview with Vanity Fair, where she opened up about going out in public and explained how being blonde helped to navigate that since it was less distinctive than the green.

In response to a question about going out in public in the 2020 iteration of the interview, Billie said: "I don't go in public anyway just because it's a complete disaster."

"Gosh, that girl was going through an identity crisis," Billie joked as she watched the clip back. "My attitude used to be I can't go out, I can't go here, I can't go there. I used to not even be able to go to a park or go get food, get coffee. It freaked me out."

"In the last year, I have been opened up to it," she went on. "I really feel grateful for that, because being able to feel confident in stepping outside without a hat and a hood, glasses and a mask and a jacket, it's so much better. And you don't have to live like that, and I realized that this year, that I don't have to live like that."

"My hair is blonde now, so it's not like the only person you've ever seen with green hair walking by and so who could it be out of the five people," she added. "It's gotten a lot easier."

The teenager previously opened up about getting tired of the green hair because it was so easily recognizable, and revealed she felt "free" as soon as she got rid of it.

"I couldn't go anywhere with that hair because it was so obviously me," she told Elle earlier this year. "I wanted anonymity." 

After dyeing her hair, Billie visited a park with a friend, which she explained was a revelatory experience. "I was like, 'No, I can't take off my hood!' I was terrified of the paparazzi and these stalkers I've had," she said. "But my friend was like, 'Don't worry: You're okay. Nothing's gonna happen.' And I took my hood off, and I felt like a new person."

Billie went on to respond to criticism of her hair, revealing that she'd seen comments from fans who missed the green roots.

"I had no goal of 'This is going to make everybody think differently of me,'" she said. "I've had different-colored hair and vibes for everything I've ever done. I wanted this album to have its own thing." 

"The other day, I posted a video from when I had green hair, and I saw people go, 'I miss this Billie, the green-haired Billie,'" she continued. "I'm still the same person. I'm not just different Barbies with different heads."
