My name is Sophie, and my best friend, Megan (pictured), has just been formally diagnosed with Alopecia totalis. We had our suspicions, her hair coming out in clumps, eyebrows thinning, but the diagnosis was still a huge blow to Meg's confidence.

I always said that if any of my friends contracted a condition or needed treatment that causes hair loss, I'd shave my head and we'd be eggs together. I intend to keep that promise, and so on August 21st, we will be getting my boyfriend and Meg's husband to shave our heads. By then, we hope to have raised £150 for Alopecia UK towards research.
