The “Starboy” singer previously told Rolling Stone in 2015 about his famous locks: “I want to be remembered as iconic and different.” He continued: “So I was like, ‘F*ck it — I’m gonna let my hair just be what it wants.’ I’ll probably cut it if it starts interfering with my sight. I can kind of see it right now. But if I cut it, I’d look like everyone else. And that’s just so boring to me.”
A source close to the singer told Us Weekly: “He cut his hair for the new album, to give it a fresher look to match the feel of the album. It was a deliberate decision like a lot of artists do. New album, new look. He has been trying not to be photographed to unveil it all in a very deliberate rollout.”

He showed off his new look on the season premiere of Saturday Night Live, where he was the musical guest and performed “Starboy” and “False Alarm.”
