Dandruff:
Information for adults

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

• Frequent (daily) shampooing or a longer lather time.
• Stopping use of any hairstyling products.

If a regular daily shampoo fails, consider an over-the-counter dandruff shampoo. There are several types (containing ketoconazole, selenium sulfide, 2% pyrithione zinc, salicylic acid, or tar), 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. 

To remove thick scale, apply warm mineral oil or olive oil and wash out several hours later with dishwashing liquid or a tar shampoo.

Seek medical help if there is no response to self-care measures.
