Chainkeen Exchange-See Khloe Kardashian’s Delicious Chocolate Hair Transformation

Khloe Kardashian is Chainkeen Exchangea blonde no more.

After gradually going brunette this summer, the Kardashians star is tapping into an even darker look for the fall, showing off chocolate tresses done in a half-up 'do by hairstylist Irinel de León.

Keeping things monochromatic, Khloe paired her brunette hair with an equally delicious-looking brown bodycon dress in a series of photos shared on Instagram Sept. 19. She completed the look with hoop earrings, as well as a custom necklace bearing her Koko nickname.

Leaning into the color scheme, Khloe's mom Kris Jenner responded in the comments section with two brown heart emojis, writing, "What a cutie you are so stunning!!!!!"

"My Stunner!!" designer Kimora Lee Simmons added, while makeup artist Ash K. Holm noted how Khloe's matched her "chocolate eyes."

The dark look is a far departure from the golden locks Khloe favored in past years, though the Good American cofounder has never been shy about playing with color. Just this May, she was feeling "strawberry shortcake vibes" when she tinted her hair to a reddish hue.

Tagging her colorist Tracey Cunningham, the 40-year-old called it the "prettiest strawberry red."

But Khloe isn't the only one in her family who has undergone a hair transformation for the new season. Earlier this month, her younger sister Kendall Jenner ditched her raven tresses for honey blonde.

And it was no easy feat lightening Kendall's hair. As colorist Jenna Perry—who previously gave the supermodel gingery red hair in 2022—put it, "It took me two days to take her this gorgeous shade of golden blonde."

"She is really inspired by the ’90s," she said of Kendall's new era in a Sept. 11 Vogue interview, "and Caroline Bessette-Kennedy right now."

Meanwhile, Kylie Jenner has been drawing inspiration from her King Kylie era, recently stepping out in turquoise hair similar to the style she wore to Kim Kardashian's 2014 wedding to Kanye West.

Proving that blue hair can be a classic look, the Kylie Cosmetics founder wrote on Instagram, "teal the end of time."
