Harry Styles chopped his shoulder-length hair off a year ago, but now we're getting to see the moment it actually happened. 

The 23-year-old singer gives fans a glimpse into the making of his debut album in his upcoming Apple Music documentary, Harry Styles: Behind the Album -- including the moment he said goodbye to his famous long locks.

"I've never had the process of making a full album in the way that I did with this one," Styles says in the new trailer, released on Tuesday. "I kind of wanted to see if I could write something that people liked without knowing everything about me."

"Anytime you're doing anything different, it's quite scary," he added, amid shots of him relaxing in the studio, diving through water and enjoying a drink.
