I’ll be perfectly honest, I can’t always keep up with Millie Bobby Brown’s hair.

Remember when she seemingly went through four hair transformations in the space of one month earlier this year?

Well, apparently, she’s still just as playful and experimental as ever.

Earlier this week, she was sporting a cute wavy blonde bob.

Two weeks ago, she had a brunette bob. Three weeks ago, her hair was long and blonde.

Five weeks ago, it was a dark shade of brown.

As of June 21, the short brunette hair seems to be back. In her latest post on Instagram, the Stranger Things actress wore her short brunette hair in a side part and a low bun, with a few pieces hanging by her face on one side.

She captioned the post simply “oh boy,” which I can’t help but think is a reference to the opening of Sabrina Carpenter’s new single, “Manchild.”

After all, the actress also posted a video of herself dancing to the song on her Stories around the same time.

Brown, who has posted several recent clips and images on social media with blonde hair, recently spoke about the bleached look on the Call Her Daddy podcast.

“People are so shocked about it,” she said, adding, “I just think I look different from what people usually see me as. It’s so fun.”
