Your doctor will probably ask you about your symptoms and examine your skin to see if you have seborrheic dermatitis. A little portion of your skin may need to be taken (biopsied) so that it may be examined in a lab. This examination aids in excluding other conditions.
Medication–infused shampoos, creams, and lotions are the principal therapies for seborrheic dermatitis in adults and adolescents. Your healthcare professional might advise you to attempt one or more of the following therapies if over–the–counter medications and good self–care practices are ineffective:
Your hair–care routine and symptoms will determine how frequently you shampoo or apply additional antifungal products. For several weeks, medicated shampoos can be applied once daily or two to three times per week. Follow the instructions on the package and allow the product to sit on your scalp for a few minutes so it can do its job. Next, rinse. Use a medicated shampoo simply once a week or once every two weeks if your symptoms have subsided. This will lessen the chance of a relapse.
Your doctor could recommend an oral antifungal drug if your illness is severe or not improving with previous therapies.
It may be helpful to use creams or ointments that contain a calcineurin inhibitor such tacrolimus or pimecrolimus. They are less likely to have side effects than corticosteroids, which is another advantage. However, the Food and Drug Administration is concerned about a potential relationship with cancer, therefore these treatments are not considered first-choice. Additionally, tacrolimus and pimecrolimus are more expensive than drugs that contain moderate corticosteroids.
