Millie Bobby Brown ditched her brown hair for a blonde new look that looks a lot like Eleven's season one wig.

The Stranger Things star first showed off a new set of long, honey-colored extensions when Miami hairstylist Dafne Evangelista shared three photos of the actress on her Instagram account this week.

Take a look at the photos, below:

In one video, Brown tells the camera, "I have hair for the first time in four years, so it’s good." (In case you didn't know, she shaved her head for during the first season of Stranger Things and has been growing her hair out ever since.)

But it turns out, this wasn't the only transformation she underwent this week. In another photo posted to Instagram, it appears as though Brown went back to another hair salon a few days later to go even blonder and much shorter.

It's unclear if her new hair is for an upcoming movie or project, but she will likely go back to her dark roots if she reprises her iconic role on Stranger Things. As of right now, the series has not been picked up for a fourth season on Netflix.

Meanwhile, Brown isn't the only celeb to change her hairstyle this fall season. Others include Selena Gomez, Elizabeth Banks, Noah Centineo, and Adam Levine, whose cornrow mohawk left fans completely speechless.
