Concern by J. M: What in my environment can be causing alopecia areata? I have a very minimal situation of alopecia areata. I have 8 dime dimensions (some even more compact) patches that are not even hairless….there are a number of hairs in them but the hair there is like orangy coloured and slim. (my typical hair is thick dark brown). No a single understands I have this condition. I was advised the odds have been it would increase again. It has been six months and it is not increasing again…I suppose I obtained far more patches along the way but all ended up truly tiny. I genuinely come to feel some thing in my environment is triggerign this immune reaction. what could it be? Could it be mould? my new canine?
