Based on my very thorough, mostly (not at all) scientific research, I feel confident stating that all evidence points to the hair naturally attached to Katy Perry’s head being a platinum-blonde bob.
But despite how fun that look is, the singer and American Idol host clearly loves to play around with wigs, extensions, and colors like the peachy-pink ponytail she recently wore on Jimmy Kimmel Live, and the elaborate brunette and red wigs she wore for a Christmas music video in late 2019.
