Selena Gomez just shaved her head, and it’s probably the most subtle hair change she’s ever made. That might seem like a contradiction, but it’s true. While she didn’t shave her entire head, the singer did shave a small section of hair off near the nape of her head to create an undercut.

Gomez’s hairstylists Marissa Marino and Tim Dueñas documented the unexpected look on Instagram. In the picture, Gomez, who has been wearing her hair in a cropped, choppy bob, is clearly wearing extensions pulled into a high braided ponytail. The placement of the ponytail revealed the surprise undercut, which was created by Dueñas. Marino then created the slicked-back plait.

"When your friend calls you to give #selenagomez an undercut... @marissa.marino killing it with the styling. Thanks for letting me join in on the fun," he captioned his picture of Gomez's hair.

No one would have ever known about Gomez's new undercut if her hair was down, making this shaved style one of the most subtle hair switch-ups she's ever made.
