Lady Gaga [1] might be the ultimate enigma of the millennial generation, but for Gen Z? That's Billie Eilish [2]. The 17-year-old singer is a walking paradox, which is why fans adore her so much. Between her oversize fashion ensembles [3], stiletto nails, and unnervingly angelic voice, Eilish is the unpredictable entertainer everyone is trying to figure out right now. But one of the most bewildering questions about her involves her natural hair colour. Turns out, it's not green.
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 natural hair colour are hidden well. Even so, we found it. Yes, Eilish's natural hair colour is blond. It's true, the curiosity regarding what Eilish's roots really look like pales in comparison to her record-breaking accomplishments, and yet it's another fact about Eilish's life stans are hungry for.
Ahead, check out Billie Eilish's impressive and eclectic hair evolution [4] through the years — starring, of course, her unexpected natural blond hair colour.

Unless you're prepared to go down a dark hole of old YouTube videos of Eilish [5] from back in the day, you have the singer's mom, Maggie, to thank for this throwback photo of her daughter. Turns out, Eilish's natural hair colour is blond, which explains exactly how she's now able to transform her colour into a spectrum of shades so easily (no in-salon lifting required).

Thanks to a surprise remix [6] to her hit record "Bad Guy" — featuring Justin Bieber, duh — fans got a glimpse of what Eilish looked like when she was a fan-girling tween. If you can pull your attention away from the impressive collection of Bieber posters, you'll notice that, here, Eilish's hair is a cool shade of golden blond — presumably her natural colour.

By the time her song "Ocean Eyes" [7] went viral on every streaming service possible, Eilish's hair was an icy platinum blond. Note: Finneas's hair glow-up.

A year later, Eilish started to experiment with her hair colour even more, albeit in a subtle way. Notice the grey undertone to her platinum hair.

Looks Eilish missed her blue hair so much that, by 2018, she went back to it — and this time, even darker. Our theory: the darker colour was the perfect long-lasting colour option for Eilish while on tour.
Billie Eilish With Pastel Blue Hair
Truth be told, Eilish's pastel blue hair could easily be the results of a washed-out dye. Still, the paler shade of blue looks too rad to ignore.
Billie Eilish With Bluish-Black Hair
Later in 2019, Eilish converted her bold shade of blue to a bluish-black, one colour that is shockingly popular among brunettes. Just look at that dimension.

Eilish only rocked this dark black hair colour for a few months, but the colour was so fitting for the star that we were convinced this was her natural colour.
Billie Eilish With Green Hair
Just as the world started to recognise how unstoppable Eilish was, she proved the fact by not GAF and dyeing her roots a shade of neon green [9]. You know, the perfect contrast to the rest of her black hair.
Billie Eilish With Brown Hair
Eilish temporarily ditched her green roots for brown hair in the new music video for the song "Xanny." [10] But don't worry — this softer look was the work of a really good wig.
