Suggest Remedy For Alopecia Areata

I am male, 30, 68 kgs, 5'9" height. Suffering from alopecia areata (single small bald patch on front/top head). I sweat a lot. When I was 20 or 21,i had the same problem in several bald patcjed. however, homeopathy cured it completely. I have medium long very thin hair. Alternatuve methods used effectively by me are raw need juice, onion juice, honey, lemon, curd ( all seperately) for massaging. There is a slight improvement with less hair fall and some little re-growth. Can u suggest me some more medication. I am eating lots of fruits daily and do 30 minutes of Yoga and stretching. thanks
