I am 20 years old and i have alopecia totalis.6 months back i lost my hair on the scalp completely.Before that I have patches on my scalp.These patches were first found whrn i was 5 yrs old.Since then after every medication the patches will be covered and new patches in another site of scalp will be founded.I was vexed with all the treatments and don't have energy to take new medications.I don't like to be bald.I want my hair back.What should i do?
