In an interview with Vanity Fair, she reflected on how her appearance affects her confidence and that her green tips made her feel too noticeable in public."My attitude used to be like, ‘I can't go out, I can't go here, I can't go there,I wasn't able to go to a park or go get coffee, It freaked me out. But in the last year I opened up to it."She further added that:"I was like, ‘I only want to be seen if I look like myself.' So I would never wear anything normal."“I went to a park with a friend, and I was like, ‘No, I can’t take off my hood!’ I was terrified of the paparazzi and these stalkers I’ve had.”According to Billie, brunette and blonde hair colors make her feel more open, free and most importantly helps her blend with others more easily.Another reason behind her decision to change her hair to blonde was to mark her new album, 'Happier Than Ever'.
