Los Angeles, California - Khloé Kardashian has swapped out her lighter tresses for a darker new 'do ahead of the holidays!

The 40-year-old reality star had been rocking a lighter brunette style with honey highlights in recent weeks, but on Thursday, she debuted a much darker hue via her Instagram.

The post featured two selfies with her hair in dark, loose waves. KoKo gave a nod to the new color by adding four brown heart emojis to the caption.

Her new look was a hit with both fans and her famous family, as her older sister, Kourtney, wrote in the comments, "Stunning inside and out my sister."
