When I was 11 years old, I had medium-length, shiny brown hair.
Then it started falling out.
I was sitting on my bed, alone, when I ran my fingers through my hair – and I noticed a smooth, round bald patch. It was about the size of a 10p coin. Suddenly, I started feeling a bit sick, like I’d been punched in the stomach. I had no idea what was happening, but I was terrified.
