My brother is facing a lot of hair loss due to dandruff. There are scales of dandruff on his scalp. His hair wash routine is after applying gingely oil he takes a hair wash. Since he finds shampoos very harsh on his hair and that they cause a lot of hairfall he uses the Godrej/Wipro Shikakai soap. He is now scared to try anything new since he has just been loosing a lot of hair :( Can anyone please suggest him something where there are less/no chances of adverse effects?
