From her teal long locks, to several short, yet bright colored cuts, Halsey’s hair has seen several different evolutions over the past few years. After a stunning start in 2015 with a Billboard Cover and Billboard Hot 100 hit “Closer” with The Chainsmokers in 2016, Halsey has kept up the momentum with a second album (which debuted at No. 1 on the Billboard 200), most recently topping the Billboard Hot 100 with her first No. 1 solo hit, “Without You.” As her success has continued to grow, Halsey hasn’t stopped experimenting with her hairstyles, either. Check out how the pop star’s hair has changed from the early days of her career, to her more recent styles in the past year.
