I have severe dandruff from past 4 years. It is so severe that when I scratch my scalp from blunt knife a thick layer of dandruff comes out every time in 7-9 days. I had tried all the treatment like homeopathic medicine, ketoconazole shampoo, oral tablets of itraconazole. I am very frustrated. My father also had same problem when he was of my age and he became bald. Please prescribe some medicine which will completely help wo treat the dandruff and hair fall problem because of dandruff.
