Most dandruff treatments are relatively inexpensive and easily accessible. One common and often successful way to keep the flakes from piling up on your shoulders is to use an anti-dandruff shampoo. Doctors suggest using anti-dandruff shampoo daily, leaving the product in your hair for five minutes and rinsing completely [source: WebMD]. When your dandruff is under control, you can decrease your use to two to three times per week. If the type of anti-dandruff shampoo you're using stops working, you can try alternating it with a different kind of shampoo.
Be aware, though, that not all anti-dandruff shampoos are the same. Different ingredients treat different causes of dandruff. Zinc pyrithione shampoos are antibacterial and antifungal. Tar-based shampoos contain coal tar, which might work well for treating dandruff caused by seborrheic dermatitis. Selenium sulfide shampoos also slow down degeneration and can reduce fungus, but be careful -- they can discolor lighter shades or chemically-treated hair. Shampoos with salicylic acid help eliminate patches on your scalp, but they can also leave your skin very dry. Ketoconazole-based shampoos are antifungal; you might want to give them a try if nothing else works, because they are stronger than the other types of dandruff shampoo [source: Mayo Clinic].
If anti-dandruff shampoo alone doesn't get the job done, you can try combining it with cortisone and antifungal creams [source: Rockoff]. These are usually sold over-the-counter, as are most anti-dandruff shampoos, but if your dandruff just won't ease up, stronger versions of both treatments are available by prescription from your doctor.
