What is the best way to exterminate or reduce dandruff? I do shampooing with anti dandruff shampoo every 2 days and it won't help. What should I do?

Medication. Prescription products include dermasmoothe, taclonex, cloves. These can reduce the problem. Sometimes oral medications such as Nizoral (ketoconazole) can be used in sever cases to treat an underlying problem. Until you see a dermatologist an application of olive oil will loosen the scales followed by a antidandruff shampoo such as t sal.
