Billie Eilish Is the Hair Color Icon We Didn't Know We Needed

Eilish kept her hair in the rooty green hue through the entirety of 2020. In December, she said fans could expect a new look after the release of her documentary Billie Eilish: The Word's a Little Blurry with Apple. "I'm changing it after the doc comes out," she said. "It'll be the end of an era, I'ma give you a new era."
