Self-Care Guidelines
Most cases of seborrheic dermatitis are easy to control with non-prescription home measures. These include:
- Frequent (daily) shampooing or a longer lather time.
- Consider 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.
- Get a little (not too much!) sun, which seems to suppress the growth of the yeast Pityrosporum.
- Eyelid changes (blepharitis) can often be managed by gentle cleaning of the edges of the eyelid by the lashes with a Q-Tip® and baby shampoo.
If a regular daily shampoo fails, consider an over-the-counter dandruff shampoo. There are several types of dandruff shampoo, 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 quite good enough. These are often added to the shampoo 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 may work rapidly but may be less helpful if used for a long time.
When to Seek Medical Care
Seek medical help if there is no response to self-care measures.
