Kim Kardashian rocked the internet when she revealed new platinum blond locks during Paris Fashion Week. But just weeks later, Mrs. Kanye West has already reverted to her darker roots — at least temporarily.

Kim's transformation from shoulder-length blonde back to long, wavy brunette was done for a new campaign shot by photographer Ellen von Unwerth. And, as People reveals, it was just a wig.

“On set a few days ago with the amazing @ellenvonunwerth,” she captioned the photo she posted to Instagram, which you can see above. “Can’t wait for you to see the projects we’ve been working on!”

Kim's close friend and makeup artist, Mario Dedivanovic, posted a photo of the reality TV star with the wig on March 17 when they were on the set of the photo shoot, which you see below.

Although it looks like Kim will be keeping the blond look for a while, she did tell People that this hair color won't be forever. “It was a really last-minute decision, and I loved taking this risk,” she said. “It’s a fun look, but I’m not sure how long it’ll last — but a fun break for now.”
