Shaved her head to take vanity out of the picture.

I saw it specualted she shaved her head for a role but it seems she did it to make a statement.

It's kind of odd though because she's basically implying it's less attractive and that's why she's doing it? She's trying to make herself look less attractive?

“I purposefully chose to look like that. I wanted vanity out of the picture,” the Oppenheimer actress, 27, told Radio Times in an interview, per the Daily Mail.

“Hollywood is very glamorous — especially for women — and it's hard for an audience to see past that,” Pugh added. “Whenever I've not needed to be glam or have a full face of makeup, I fight to keep it that way. It helps the audience."

"Vanity is gone. The only thing that people can look at then is your raw face," she said.

“Even at the beginning of my career, I was always fighting to control my image,” Pugh also said. “It helps me when I'm wearing less makeup because then I'm less of a sparkly thing on screen. I feel like I'm allowed to do ugly faces, like it's more acceptable.”
