More than a year after the release of her debut album BadlandsHalsey has already proven there's no cut, style or dye she won't try.

So, what is Halsey's hair story, and where does it begin? In March 2015, the dauntless alt-pop star widened her audience at the Pandora Festival, where she sported long blue locks that functioned as her own on-stage waterfall. Within a month, most of her mane was gone in favor of a slick, greener high-and-tight. And by the year's end, she'd bleached her 'do, buzzed it off completely and started anew. Out with the old, indeed.

And then came 2016...

Whether Halsey's sporting short dark bobs or subtler shoulder-length waves, the "New Americana" singer's proven that change is a good thing, particularly where the top of your head is concerned. Look back at all of Halsey's hair transformations since breaking out with Room 93 above, and share which style is your favorite in the comments.
