Billie Eilish Wore Her Most Voluminous Hair Ever to the 2024 Oscars

No matter how you picture Billie Eilish's hair — whether that's with bright red (recently retired) roots, neon green (long-retired) roots, or shaggy blonde — one thing has almost always been true: it leans on the flatter side. And I don't mean that in a bad way! I love her sleek style. So imagine my surprise when she arrived at the 2024 Oscars with the most voluminous blowout of not just her career but quite possibly the entire Academy Awards red carpet.
