The reality star and mum to daughter True Thompson uploaded the transformation, captioning it "You'll never get the same moment twice. Appreciate this moment."
Well, we know for sure that we're appreciating Khloe's fun new hair!
A slight change from her usual sandy blonde tresses, the transformation came just before the 34-year-old announced a collaboration with pal Malika Haqq and Becca Cosmetics.
Despite her girly locks, Khloe has proved that no matter what he hair - she's still the protective younger sister we've seen in action on Keeping Up With The Kardashians.
On Dec. 17, big sister Kim posted a throwback photo of herself on Instagram, which younger sister Kylie Jenner commented "Omg Chicago" due to the resemblance of Kim and her youngest daughter. However, one user disagreed saying Chicago "would either look MORE like Kanye or the surrogate mother."
Jumping to her sister's defence, Khloe wrote "Your passive wanna be petty comment is simply uneducated. Chicago is completely Kimberly's biological child. Praise the lord she was able to have a surrogate and that we are blessed with sweet gorgeous Chi Chi."
"Chicago is Kimberly's DNA. Her and her husband made embryos and then they were blessed enough to have a surrogate carry their child for them since Kimberly is unable to. God bless modern medicine."
