Hi, i am a 31 year old woman. I would like to know whether greying of hair can be reversed COMPLETELY? If yes, is Melnora gel effective or are natural home-made remedies more effective? Also, if these do happen to reverse the greying, how long does it last? Wouldn t the greying come back once the effect of the above wears off? Is colouring (L oreal, Godrej) of hair safe or does it spoil the hair? And once you colour, is it that you need to keep doing it? Also, do psychiatry drugs cause acne? What is the best and most effective remedy to combat that, while the psychiatry drugs are still on, considering you cant stop those medicines?
