Am facing problem of Hair loss since last 3-4 month. It started with one/two patches on back side, but seems to be growing in other areas. It appeared around my Mustaches and had to be clean shaved now. I know this is Alopecia areata (Undri).Appreciate to help me how do I prevent it and also regain my lost hair .Also need to know if this has any linkages with Garlic. as being high BP patient, am consuming raw garlic with lunch since past 3-4 months.

Thanks and regards;
