How do I use ketoconazole shampoo?

To use your ketoconazole shampoo, get your scalp thoroughly damp, apply 1 tsp of shampoo, work it into a lather, and then let it sit on your scalp for five minutes before rinsing completely with water. You should wash your hands before and after use.

Typically you'll apply it at least 2-3 times per week, but be sure to follow the dosage directions on the package or outlined by your medical provider.
