Megan Fox is switching it up again.

The “Transformers” star debuted a chic brunette bob on social media over the weekend, going back to her natural hair color after rocking a series of playful hues the past few months.

“she’s a brunette again,” Fox captioned the pics.

The “Transformers” actress captioned the pics, “she’s a brunette again.”

It’s not the first time the actress, 37, has experimented with her locks.

Last month, she showed off another glam ‘do – her hair dyed a light shade of blue.

“entering my jedi era” she captioned a series of photos of herself sporting the blunt, pastel-colored bob.

The look was a change from earlier this year when Fox attended a Super Bowl party with longer pink-hued hair.

When it comes to beauty, hair color and length isn’t the only thing Fox has experimented with.

The “Pretty Boys Are Poisonous” author has been open about the plastic surgeries and procedures she has undertaken, including three breast augmentations, a nose job, botox and fillers.
