Kaley Cuoco is fearless when it comes to trying different hairstyles and hair color. The "Big Bang Theory" star confessed that she has no worries and is always down to experiment when it comes to coloring and chopping her hair. In fact, she had tried a pixie cut and rocked a hot pink hair. "Just blink and it might be blue or something," the CBS star told Us Weekly. "I always do something stupid to it. It's hair! It grows back."
