Seborrheic Dermatitis:
Information for adults

Most cases of seborrheic dermatitis 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.
• A little (not too much!) sun – this seems to suppress the growth of Pityrosporum.
• Managing any eyelid changes (blepharitis) by gentle cleaning of the skin around the eye lashes (eyelid margins) with a Q-Tip® and baby shampoo.

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 shampoo.

Some over-the-counter creams will help if the medicated shampoo is not working well enough. These are often added to the shampoo use until you notice improvement and then can be discontinued, to be used again temporarily when needed. These include:

• Creams that reduce the Pityrosporum yeast (clotrimazole, miconazole, terbinafine).
• Hydrocortisone cream, which may work rapidly but may be less helpful if used for a long time.

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