Last December, Halsey shared a selfie simply captioned with five scissor emojis. The Badlands singer had shaved her hair off. Now she's opening up about why in the June/July issue of Nylon.

"Hair has also been a big indicator of racial issues in my life," Halsey, who is biracial, told the magazine. "It’s one of the ultimate symbolic struggles for women of color. Shaving my head was important to me because I needed to be able to prove that I could still love myself if I did it."

It was a fierce move for the star, who was previously known for her flowy, mermaid-blue tresses. Then she snipped those off into a trendy pixie cut prior to completely shaving everything. But no matter how she wore her hair, strangers on the Internet had something to say about it.

After she ditched the blue, she "saw thousands of tweets from kids who were like, ‘Yeah, that’s it, I don’t want to be her fan anymore.'” Yeah, that makes total sense, since hair length directly correlates to musical talent ... *sigh*

Then there are the "straight white dudes" -- Halsey's exact words -- who fill up her Twitter mentions with rude comments about her short hair.

"I’m like, ‘That’s cool dude.' I really could not care less about what you think," she said, later explaining that "there are some things [she has] the power to make a difference in, but people being mean on the Internet is not one of them."

Halsey's got better things to do than engage her trolls -- like sing her heart out to a sold-out Madison Square Garden to close out her Badlands Tour this summer. Casual.
