Six months ago I had a small bald patch on my beard. Today it's been growing and spreading. I've got one really big patch under my chin and a small one the size of a dime about an inch away. It's obviously spreading. I thought it might be a fungus maybe from a dog. However, it doesn't itch, it's got my skin pigmentation except that it's completely bald with the exception of tiny, small, no pigmentation hairs growing on it.
Two things happen 6 months ago: I came in contact with a dog with skin issues and I became a vegetarian. My father did tell me when he was my age he had a similar issue except it never spread and it went away after a month or so. Anyone have an idea what this might be? Thank you. Oh I don't have health insurance and cannot afford to see a dermatologist.
