Management Pet Care Essentials LinkOut - more resources Scaling of the skin on the scalp, eyebrows, forehead, ears, and beard area is typical. Some cases may also involve the central chest, underarms, groin, and around the belly button. In darker skinned patients, this scaling can have a flower-like shape (thus the term petaloid seborrheic dermatitis). Discoloration of the skin with lightening or darkening of affected areas may also occur. It is sometimes itchy. A dermatologist can determine if you have seborrheic dermatitis by clinical examination. In rare cases, a skin scraping or biopsy may be necessary to confirm the diagnosis or to rule out other explanations for your symptoms.

The redness, itching, and scaling associated with seborrheic dermatitis are caused by changes in skin cell functioning.6,7 Malassezia yeast seems to cause a nonspecific immune response that begins the cascade of skin changes that occur in seborrheic dermatitis.6 Malassezia is a normal component of skin flora, but in persons with seborrheic dermatitis, the yeast invade the stratum corneum, releasing lipases that result in free fatty acid formation and cause the inflammatory process to begin.8 Malassezia thrive in high-lipid environments, so the presence of free fatty acids enhances the growth of the yeast. The inflammation causes stratum corneum hyperproliferation (scaling) and incomplete corneocyte differentiation, which alters the stratum corneum barrier and impairs its function, thus increasing access for Malassezia and allowing water to more readily leave the cells.8 Psoriatic Arthritis Microbial Sensitivity Tests Sometimes, seborrheic dermatitis will clear up by itself.
