Can hair regrow normally for men. If yes do we need to follow any diet or anything else for that to happen. I have lost most of my hair due to dandruff,hair fall, itchy scalp. I have consulted 3 dermatologists so far. Still hair fall is not cured. Dandruff is controlled and itchiness on scalp also reduced. I have lost natural shine in my hair and white hair is also started to grow . I'm in a state of dilemma to consult 4th dermatologist. I couldn't concentrate on my career due this problem. It is frightening. Through medical tests I found that I have Vitamin D, B12 deficiency. I took vitamin tablets which my dermatologist has prescribed for a period of 3 months still nothing has changed. Please suggest
