Her blonde hair had a good run, but now, Kim Kardashian is revisiting her natural hue. Over the weekend, the reality star took to Instagram to reveal her au naturel look, captioning a shot of her tawny brown strands with, "I'm back." We admit -- we loved Kim's warm gold highlights, but no one wears a deep brunette shade quite like the star, and the low maintenance vibe is much more in line with her busy schedule as she balances her roles as mommy and mogul. "I loved that no one recognized me as a blonde, but it required so much upkeep that I went back to my natural color," she previously told InStyle on her first time going blonde. "I did not want to spend my free time in the salon chair." Take a closer look at Kim's hairstyle, and see even more celebrity hair makeovers in our gallery!
