Hello doctor, i have severe hairfall & i recently (about a month) noticed a small bald patch on my head. When i consulted my dermatologist, he said its alopecia areta. So he has prescribed Folifast hair tenure & Biotal tablets. The treatment started only a week back. Will this treatment he has suggested be effective? and also i have recently found few grey hair on the head. what should i do about it? i have a mild dandruff problem. so i m using ketoconazole shampoo for that.
