Katy Perry is known just as much for her music as she is for her eye-popping outfits — a fact that hasn't gone undocumented. But every once in a while, the pop star does something so dramatic with her hair that her outfits almost look tame by comparison.
Whether it's pink, blue or topped with a yellow cube, Perry's daring hairdos are always something to look forward to.
