No one does hair quite like Billie Eilish. When the singer-songwriter opts for color, she goes bold and leans all the way in. Jewel-toned reds, electric greens, and ocean blues -- it's safe to say there isn't a color Eilish is scared to try. Even her haircuts and styles seamlessly transition between long layers and voluminous bobs. A beauty chameleon (to put it lightly), her hair looks are almost as cool and transformative as the lyrics she writes. Almost.
