Megan Fox Shocks with Blunt, 'Blue Jeans' Colored Bob in Dramatic Hair Transformation

Megan Fox is feeling blue.

Blue hair, that is.

The Jennifer's Body star, 37, debuted a brand new hair color and style on Tuesday — and it's a far cry from her baby pink locks she was previously rocking.

Fox's hairstylist, Dimitris Giannetos, shared an Instagram carousel of Fox's new "blue jeans" hair color and blunt bob style on Instagram, revealing that he'd used L'Oréal Paris Féria Multi-Faceted Shimmering Permanent Hair Color in Sapphire Smoke ($10 at amazon.com) to achieve the actress' new fun shade.

"'Blue Jeans' hair color and blunt bob for the one n ONLY @meganfox !" he wrote, adding that he used the color Sapphire Smoke for her.

Fans knew something was coming when the actress shared a carousel of her own on Instagram on Monday with a collection of photos of her bubblegum pink hair. She wrote in the caption, "in memoriam of my pink hair era february 2024-april 2024." No doubt the pink hair was about to go, but we had no idea what was in store!

Fox is no stranger to changing up her hair color. Last November, she revealed a fiery red bob in New York City while promoting her poetry book Pretty Boys Are Poisonous. She styled her chin-length hairstyle in a center part and wore it curled under for the event. Much like her current style, she opted for a shadow root rather than taking the color all the way to her scalp. This makes the color look even more natural (as natural as a rainbow color can be, anyway!).

Last summer, though, Fox went for a more natural look, wearing her hair past her shoulders in a copper shade. She shared photos of herself in a swimsuit with her hair down and in a natural wave, letting her locks do their thing as she soaked up the sun.
