The 16-year-old E! star posted a photo on Instagram showing off some very blond tresses on the bottom half of her head, which hints that she may be the latest sister to say sayonara to the dark side and the newest member of the light locks club.
"Oh no, what is stas doing to my hair," Jenner wrote with the photo, referring to her friend Anastasia Karanikolao.
However, Kylie's blond look may just be a transition to something even more eyebrow-raising shade.
Khloé Kardashian Odom, who is apparently also undergoing a dye job, Instagrammed a photo of her and Kylie as they were about to get the process started and wrote, "Tweedle Dee and Tweedle Dumb painting their heads blue! MSFTS these days @kyliejenner @iputtheindustryonmyback."
Well, they wouldn't be the first, that's for sure.
