Check out the most surprising celeb transformations of the week...

The Transformers star is seeing red.

After testing out the fiery hue with a wig in October 2022, Megan dyed her signature dark locks a crimson color for Vanity Fair's Oscars After-Party March 12. In a video posted to the magazine's Instagram, she revealed her decision to dye her hair was inspired by her love for Greek mythology and wanting to tell the story of someone returning from hell. 

"If all the fire and brimstone from hell was in your hair," Megan explained. "If you were queen of the underworld, what would you look like walking the red carpet?"

Goodbye, bob. Hello, pixie!

The Fabelmans star is once again rocking a cropped hairstyle, walking the Oscars red carpet with freshly cut hair. Michelle's hairstylist Chris McMillan documented her getting-ready process on his Instagram, posting behind-the-scenes photos and revealing he had chopped her hair the night before.

"Love a 'boy cut' on Michelle always," Chris wrote in his caption, adding that they opted for a "soft wheat" platinum blonde hair color to complete her look.

Less than one week after dyeing her hair copper, the Cravings author was "pushing it a little more" by going for a more orange tone for the 2023 Oscars. 

Chrissy documented the process on Instagram March 11, sharing a video of hairstylist Matt Rez as he washed the bright ginger color out of her hair. 

The model made her most dramatic hair transformation yet when she revealed a pixie cut in a March 20 Instagram post. Emily rocked the shorter strands in several behind-the-scenes snapshots of her recent photoshoot with Pop magazine.

In one image, The High Low with EmRata podcast host showcased her spikey 'do while donning a all-white look that consisted of a sheer lace top and cutout pants with fish-netting.
