Billie Eilish is no stranger to chopping (quite literally) and changing her hair. I mean, over the years we've seen her rock many a' colour and in recent months, she's – once again – ditched the blonde for her trademark jet black tone... though, that is minus the iconic green rooted highlights *collective sigh*.
Having said that, with the singer's latest main feed Instagram post, which was shared just short of 24 hours ago, she's not only sporting a fresh colour job but the look is also accompanied by some XXL dark hair extensions. Uhhh guys, this is the longest her locks have ever been! Rapunzel, eat your heart out.
The 10-part carousel arrives to us as an interview with media brand, High Sobriety where Billie also debuted her latest fragrance, which is aptly named Billie no. 2. Letting the pics do all the talking, she kept the caption v caszh, writing: "@HIGHSNOBIETY @BILLIEEILISHFRAGRANCES".
As shown, Billie's lengths are super duper long, so much so that they reach her hips. And not only that, but they have also been styled in her signature way, pin-straight. Side note: do you seen that shine?! We like to call this glossy look 'glass' hurr.
In said interview, Billie shares her thoughts and feelings surrounding hair and the power it can hold. "I feel sexier when I dress masculine", she introduces and continues by saying: "I didn’t feel sexy for one second of being blonde.
"When I was blonde, people treated me differently. People completely changed their demeanour [around me]".
Everyone's clicking on...
Despite her thoughts, we just wanted to say that we think you look sexy no matter your hair colour, Billie! But this hair look? Well, why it's a complete serve, ofc.
