Signs and Symptoms of Seborrheic Dermatitis
The most commonly affected areas of the body—the scalp (particularly in infants), mid-face, ears, chest, and groin—become red and inflamed and have a greasy, waxy scale. There can be periods of intense redness and inflammation, especially along the eyebrows and cheeks, followed by periods of relative quiescence. Infants have diffuse, thick, waxy scale on the scalp, a condition called cradle cap, that is not itchy.
Seborrheic Dermatitis Diagnosis
Diagnosis can be made based on a visual examination. It should be differentiated from other forms of eczema, psoriasis, and rosacea.
