Seborrheic Dermatitis Treatment
Seborrheic dermatitis, sometimes called seborrhea, is a skin condition that primarily affects the scalp, although it can affect the skin as well. Only approximately 3% of the total population suffer from seborrheic dermatitis, with the highest incidence noted in those with acquired immunodeficiency syndrome (AIDS). Seborrheic dermatitis may be easily managed using nonprescription treatments, but in some cases, a doctor's assistance is required for more aggressive treatment.

Seborrheic Dermatitis: What Is It?
-
Seborrheic dermatitis is typically found in the scalp, although it also affects oilier parts of the skin where sebaceous glands are present, such as the face, trunk and back. The condition causes itchy, scaly red patches and is one of the causes of persistent dandruff. Seborrheic dermatitis isn't life-threatening; however, it can cause great discomfort and embarrassment to those who suffer from it.
The Causes
-
The exact cause of seborrheic dermatitis isn't known. However, according to the Mayo Clinic, there are certain factors that can exacerbate this condition, including stress, fatigue and seasonal changes. Seborrheic dermatitis is seen more commonly in those with AIDS and neurological conditions such as Parkinson's disease. The condition can also be caused by Pityrosporum ovale, a yeast that is normally present on the body. When this yeast grows abnormally fast, however, skin problems such as seborrheic dermatitis may arise. The Mayo Clinic states that the effectiveness of antifungal medications in treating seborrheic dermatitis seems to support this claim.

Scalp Treatment
-
According to the Mayo Clinic, over-the-counter medicated shampoos are the first treatment used in seborrheic dermatitis of the scalp before anything stronger is recommended. Look for dandruff shampoos that contain ketoconazole, ciclopirox, tar, pyrithione zinc, selenium sulfide, or salicylic acid as the active ingredient. Use the shampoo every day, and make sure to leave the product in the hair long enough for it to work (three to five minutes). If seborrheic dermatitis of the scalp begins to resolve and you notice fewer dandruff flakes on your shoulder, cut back to using the shampoo two or three times a week. If the condition doesn't improve, see a doctor or dermatologist for a prescription treatment.
Treatment for Face & Body
-
To treat scaly, itchy patches on the body, use of over-the-counter antifungal or anti-itch creams can be helpful. However, you may require a doctor's help to get the best result. Your doctor or dermatologist may prescribe a topical corticosteroid or antifungal medication--or even both--or an oral medication called terbinafine if seborrheic dermatitis is noted on a large part of your body. Treatment for seborrheic dermatitis of the body may include prescription oral immunomodulators, which reduce inflammation and fungus growth. However, the U.S. Food & Drug Administration has determined that this medication should only be used when all others fail because of the effect they have on the autoimmune system; additionally, they should only be used for a short time.
Helpful Tips
-
In addition to using special shampoos and creams to treat seborrheic dermatitis, the Mayo Clinic suggests making certain simple changes in lifestyle, such as avoiding use of harsh (detergent) soaps on the body, wearing cotton clothing to prevent further irritation, and avoiding the temptation to scratch. Because seborrheic dermatitis gets worse when the affected area is covered by hair, men may want to consider remaining clean shaven rather than grow a mustache or beard.
