Seborrheic dermatitis is caused by an allergic reaction to a certain type of yeast that occurs naturally on your body. When it over grows on your skin, it creates red patches with scaly skin on the surface. When it occurs in your scalp, it is called seborrheic and causes dandruff and can cause hair loss. If you have a disorder of your immune or neurological systems, you’re more likely to develop seborrheic dermatitis. Outbreaks are also triggered by stress, fatigue, and cold weather.

How Is Seborrheic Dermatitis Treated?

Dr. Agha can often diagnose seborrheic dermatitis by physical examination. The condition can appear similar to psoriasis. Occasionally, Dr. Agha will obtain a skin sample to examine under the microscope. Prescription shampoos and lotions can successfully treat seborrheic dermatitis. In some cases, internal medication is required to correct the problem.

Washing your hair and face regularly can help, and sunlight can abate the growth of yeast.  Seborrheic dermatitis is not contagious and cannot be spread to others, but may recur or persist.
