Billie Eilish [1] is unlike other celebrities, which is why fans adore her so much. Between her oversized fashion ensembles, stiletto nails, and unnervingly angelic voice, Eilish is a unique entertainer that we like to follow. But one of the most common questions about her involves her natural hair color. Turns out, it's not neon green or jet-black [2] with red roots (though she looks great in those different styles).

Fun facts about Eilish are aplenty on the internet (did you know dance was her first true passion before she suffered a severe injury?), but details about her real hair color are not as wildly shared. Even so, we found it — and it's a look we've seen her in before. Eilish's natural hair color is light blond. She returned to the look [3] in 2021, shocking fans when she debuted a platinum hue on Instagram. However, she quickly went back to a bolder color shortly after. "I feel sexier when I dress masculine. I didn't feel sexy for one second of being blonde," she told High Snobiety [4] in an interview. "When I was blonde, people treated me differently. People completely changed their demeanor [around me]."
