I'm having alopecia areata from last 8-9 years. Now I don't have any spot on head, but my both eyebrows n eyelashes, mustache n 60% of beard is gone n some spots on both hands n legs. I have consulted doctor he said to take injection (steroid) therapy n Platelet Rich Plasma (PRP) therapy both alternately only for facial hair. My question is will it give good results n cure me completely and mainly can steroid have any side effects in future. If yes then what kind of side effects? Please help me.
