Kim Kardashian ditched the blonde hair to go back to her days as a brunette.

The reality star uploaded a photo of her recent hair color change on Instagram on Feb. 1 with the caption "I'm back." A day later she posted another photo of herself in bed and wrote "So sleepy."

Kardashian first showed off blonde hair in 2012. She later went back to the light shade almost three months after giving birth to North West on June 15, 2013.

"Using a repair treatment like Joico's Revitalux is crucial, as well as a violet tinted shampoo like Joico's Color Endure Violet Shampoo to maintain the delicate blonde tones of the hair."
