Dandruff:
Teen information

Most cases of dandruff are easy to control with non-prescription home measures. These include:

• Frequent (daily) shampooing or a longer lather time.
• Use of shampoos containing ketoconazole, selenium sulfide, 2% pyrithione zinc, salicylic acid, or tar-based shampoos.
• Discontinuation of hairspray, gel, mousse, and other hairstyling products.
• Stress reduction and a healthy diet, especially with adequate B vitamins, zinc, omega-3 fatty acids, and reduction of sugar- and yeast-containing foods such as bread, beer, and wine.

If a regular daily shampoo fails, consider an over-the-counter dandruff shampoo. There are several types and one may work better than another. Sometimes one will work well for a time and then become less helpful; then it may help to switch to a different type.

If the scalp is covered with widespread, dense scale, the scale may first be removed by applying warm mineral oil or olive oil to the scalp and washing several hours later with a detergent, such as a dishwashing liquid or a tar-based shampoo.
Seek medical help if there is no response to self-care measures.
