I am 37 years male. I have been experiencing hair fall from last few months. Esp when I oil my hair or shampoo them. There are no patches at all on my skull. I never had this problem earlier but this is there from last 1-2 years. Last year I moved to china since then I have been experiencing high hair fall. I am using paraben and sulphate free shampoo of brand wow and also hair oil of same brand and having diet like breakfast, lunch and dinner. I see that very less hair are falling off while sleeping but major hair fall is when I shampoo or oil them. Please suggest. I am quite worried.
