How to Use Ketoconazole Shampoo

For best practice, it’s important to follow the instructions of your doctor and the instructions indicated on the product label.

If you’re using this antifungal shampoo on any area other than the scalp, apply it to the affected area and let it sit for five minutes. Then, wash it off thoroughly with water, and then dry your skin.

To prevent any negative reactions, it’s recommended you do a skin patch test with the shampoo to see if any irritation is caused by the application.
