Try Nizoral shampoo. My dandruff got sooooo bad, I was scratching my poor scalp to death. I had tried Head & Shoulder, Selsun blue, other ointments to ward off the flakes, but nothing helped. I finally went to my doctor and she wrote a prescription for Nizoral. They sell it in stores, but she wrote a presciption so I would get the strong stuff. You must leave on for 5 minutes. This worked wonders for me. I have not run out of the prescription yet, but I will try the OTC strength when this runs out. Pricey stuff, but hey it works for me. Good luck.
