Maybe brunettes, not blondes, have more fun—just ask Kourtney Kardashian.
The Kardashians star recently kissed her platinum locks goodbye and officially went back to her roots. Taking to Instagram on May 21, Kourtney unveiled a jet-black look, cheekily captioning her post, "brunette4lyfe."
The Poosh founder shared a carousel of photos that showcased her new look. In one image, she slicked down her long bob, tucking the sides behind her ears and parting it in the middle. She paired her edgy 'do with a bold, black smoky eye and white overalls layered over a black-and-white Blink-182 band tee (a sweet nod to husband Travis Barker, 47). Another snapshot featured Kourtney—with a deep side part—wearing a lingerie slip dress that consisted of a ladybug print and lace trim.
The 44-year-old's transformation comes just two months after she bleached her hair blonde. In March, while enjoying a Las Vegas trip with Travis, Kourtney debuted her lighter tresses during date night at the UFC 285 event.
Kourtney, who has been blonde before, previously explained why she doesn't keep the hair color for a long time.
"I kept this hair color for only a month before dying my hair light brown with highlights," she shared on her now-defunct app in 2019. "When I was getting my highlights touched up, all of them fried off and I had spikes of hair that stuck up so I dyed my hair black and cut it short."
And while people typically go lighter in the summertime, Kourtney isn't the only star to bend the rules. Keep scrolling to see all of the latest celebrity hair transformations.
