Kelly Osbourne isn't afraid to make bold choices when it comes to her hair.
"I love experimenting and trying new looks," she told Us Weekly in 2010. "It's fun to change it up."
No kidding. Since 2002, Osbourne has rocked several hair colors, including lavender, pink, gray, blonde, black and brunette. The Dancing With the Stars alum has also experimented with length, sometimes opting for a short buzz and other times choosing long extensions.
