Kardashian and Atkin were also seen debating on the length of the reality star's cut.
"You guys, how cute is my hair?" Kardashian asked her followers once her look was complete. "Thank you, Jen!"
After the chop, Kardashian explained to her followers that she didn't cut her real hair.
"You guys, I didn't cut my real hair," she said. "I braided up all my long hair, and I sewed on extensions, and we cut the extensions. I have waited far too long to grow my hair to cut it. So, everything is changeable."
Kardashian later used Instagram to give fans a better look at her new 'do, posting a shot of herself posing in a zen-like garden.
"I'm a pink starburst!" she wrote. "I repeat, I am a pink starburst!"
