F.M.
Hi J., I have alopecia also but, I started six years ago when I think it was caused for too much stress. The first time I go one spot as a dime size and and then two more and the largest was three inches circle. I went to the doctor and honestly nothing help but time, for my hair to growth back. now I get those spots every year one or two but not as big as the first time. what I do now and I think it helps I put a little piece of alovera plant(only the jelly) when it starts a leave it for 10 minutes every day.
Good luck
