It’s safe to say Billie Eilish likes to experiment with her look. If her iconic collection of pattern-adorned matching t-shirt and short sets weren’t enough (check out her Glastonbury performance to see what we’re talking about) she’s dyed her hair more times (and colours) than we can keep track of. From grey and ash-blue to teal and lavender, we’re not sure whether there’s any colour she wouldn’t go for – and her latest move proves it.

Taking to her Instagram stories to reveal her latest look, Eilish paired neon-tinted glasses with a green and black bandana to match her new hair style – a natural brown length with bright neon green roots. You read that right – while from the surface her parting is the only patch which looks anything out of the ordinary, underneath her whole head is completely green. 

It wasn’t long until Eilish’s fans took to Twitter to share their thoughts – and they were just as in love with the new look as we are. 

Eilish’s successful makeover is no happy accident though – neon is this summer’s biggest fashion trend. Of course, Eilish found a way to make the trend unique to her, but our neon obsession has been slowly and surely trickling into the beauty industry for a while now, first through nails and, more recently, neon eyeliner, as seen in Fenty’s summer collection.

Now, Eilish has shown us how to effortlessly take that trend to hair – and this is the advice Stylist’s very own beauty writer Hanna Ibraheem had for anyone bold enough to try this look themselves. 

“Dying the roots is a good way to try it, if you’re scared to go neon all-over your head,” she explained.

“However,” she continued, “if this is a style you want to keep, you would need to be good with maintenance every time your roots grow out.”

Sure, it might be a lot of hard work, but it looks bloody great.
