The 21-year-old actress admits she hasn't always been a bubbly, healthy blonde.
She tells MTVu.com, "When I was about 15, my lowest weight was 85 pounds... My hair was falling out but I was more scared that 85 pounds wasn't good enough."
Snow knew it was time to get help when she had to start mutilating herself to stop the hunger pains: "My rock bottom came when I started cutting a lot."
The actress checked into rehab at 19, as her career was taking off in TV drama American Dreams.
