It's a time-honored tradition that every Kardashian-Jenner sister must, at one point in her life, go blonde and Kourtney Kardashian is the latest to get the bleach bug. The eldest sister just made a shocking change to her look, not just with a fresh trim but with a bright new hair color — a massive departure for Kardashian, who has stuck to her natural deep brunette hair color since the rise of the Kardashian crew in late '00s.

Kardashian's new blonde comes courtesy of stylist Cassondra Kaeding, who took the reality star slash Poosh and Lemme founder from dark brown to a shimmery pale blonde; it's the creamiest, dreamiest almost-platinum, contrasted against Kardashian's dark brows and eyes. According to a subsequent Instagram post, Kardashian took her new color on a road trip to Las Vegas, where she posed beside the slot machines and alluded to a desire to change things up with a Hunter S. Thompson quote as the caption.

While Kardashian is known as a brunette, she has actually been blonde before. She shared a throwback snapshot of herself in 1995 saying she was "bored during finals" and used dye as a way to procrastinate her schoolwork. Relatable. (The color was a little warmer than her current shade, as DIY blondings can be.)

Kardashian has been rocking short hair for a while; she chopped off her long lengths around the holidays and has been having fun experimenting with a bob style. It looks like she took off just the teeniest bit of length alongside the bleach job, as her hair now skims her jawline for a '90s supermodel vibe, which really works with Kardashian's gothic rocker chic style. Sometimes you just gotta grab the scissors and the toner and go for it.

Almost all of the Kardashian-Jenner sisters have experimented with blonde, most notably Kim's Met Gala Marilyn platinum. Khloé, of course, is a natural blonde, and Kylie has channeled her blonde ambition with a golden hue in the past. Little sister Kendall Jenner is the only holdout from a bleach job, though she has gone blonde via wigs on the runway and in photoshoots. Matriarch Kris Jenner, never one to be upstaged by her daughters, has also experimented with the lighter side with wigs, including a buttery bob at the 2019 Met Gala.

Will Kourt's blonde stick around or is this a brief trip to Blondesville? We'll have to wait and see if the transformation shows up on the next season of The Kardashians.
