Hi doctor, In my head I have few patches white in colour as like skin it is stuck to the scalp and when I comb or using nail I scratch them and it looks like skin and blood comes from that spot. I really don't know what this problem is. Another problem is lot of hair fall, is it due to this white skin like patches in the scalp or I don't know what is the issue hair is falling like anything and I have lost 10 times the density of the hair that I have now in my scalp. Could you suggest me some solution for it.
