74 year old white male.  Starting getting bald spots in hair and in beard about 13 months ago.   Looked on line and decided to heal myself.  Started taking Quercetin 500mg 4 per day and drink buckwheat tea 2 times daily.   My hair has started growing in and filling the bald spots on head and beard within the past 4 weeks.   I honestly do not know if this self curing process is the cause on new hair growth or not.  But it is not expensive and in my world it helped.   Also I lost all of my eye brows and eye lashes.  Brows are coming in strong but nothing on the lashes so of now.  Good luck people
