I'm sure she's a natural blonde. She once said that she died her hair red to get noticed more in LA for her Music career, but then she went back to blonde because it felt more natural for her.
Also, at the ISF empoweresque event Zach has a pic of a Young Candice on his t-shirt and she's got blonde hair then and on "When I Was 17", she had blonde hair on a lot of those pics and it looked natural. So I think she is a natural blonde. :)
"Red Heads have more fun but I always felt like I was wearing a wig. I feel most like myself as a blonde."
"I thought I'd be edgy and dye my hair red," she said. "And I dyed my hair, like, Jessica Rabbit red. It kind of allowed me to have this whole new confidence and this whole new swagger and this whole new sense of self. It kind of brought out the inner rock star in me. I had never dyed my hair like that, and no one forgot me after that."
