That's not a wig!

After two months of not dying her hair and wearing wigs, Kylie Jenner showed off her new blonde tresses on Instagram.

Along with the sultry snap, the 18-year-old wrote, "Took months of not dying my hair and wearing wigs to get my hair back to health so I can do this!! Thank you @priscillavalles @maishaoliver for putting up with me all day. I'm going for an ashy dirty blonde for the fall. But this shits a process! I'm coming for u khloé!"

It's pretty amazing that the teen queen probably worked harder on her hair than she did at school. Oh the priorities of the Kardashians!

Also -- we gotta say with the big new lips, big new hips an now blonde locks a la Khloe -- we kind of think Kylie might be pulling a Single White Female on her big bootied sis! You better watch your back, Khlo! (And your stilettos)!
