Celebs like Rihanna, Taylor Swift and Madonna don't mind working their natural, wiry waves
Long before Katy Perry was known as Hollywood's color chameleon, the multicolored crown was worn by this singer. "I went through a stage where I was dying it blue, purple, pink and wearing really colorful clothes. But you have to bleach it before you put the color on and that was ruining it," she told ContactMusic.com. "Someone said you have to stop otherwise all your hair will drop out. I seriously didn't want that to happen. So I ditched the color and went back to being natural again."
