What is Nizoral A-D?
Nizoral® A-D is an over-the-counter shampoo that treats the flaking, scaling and itching from dandruff. Nizoral® A-D contains 1% ketoconazole, an antifungal drug that works against pityrosporum ovale, a fungus believed to cause a common form of dandruff. One research study showed that Nizoral® A-D cleared up dandruff in 80% of people who used the shampoo twice a week for four weeks. The shampoo also comes in prescription form with 2% ketoconazole.
How do I use Nizoral® A-D?
Apply Nizoral® A-D to your wet hair and scalp with enough shampoo to produce lather. Gently massage your entire scalp for about one minute, then rinse and repeat for another three minutes. Use Nizoral® A-D every three to four days for up to eight weeks if needed, or as directed by a doctor. Then use it only as needed to control dandruff.
Side effects of Nizoral® A-D
Nizoral® A-D does have side effects, but they are rare for users of the over-the-counter dandruff shampoo. The side effects of Nizoral® A-D may include an increase in normal hair loss, dry skin, and itching. Again, these side effects from Nizoral® A-D shampoo are very rare. It can also remove the dye from colored hair or curl from treated hair as well.
