What Causes Dandruff?

Seborrheic Dermatitis

Seborrheic dermatitis, also called seborrheic psoriasis and seborrheic eczema, is a skin condition that mainly affects the scalp and leads to dandruff, reddened skin, and scaling patches. Some patients also experience symptoms on oily parts of the body including the chest, eyelids, ears, eyebrows, sides of the nose, and face. The severity of the condition and places it manifests vary from case to case. Sometimes the condition resolves on its own and doesn't require treatment. However, some patients do need multiple treatments to make the issue go away, and they may experience recurrences. It helps to cleanse daily with a gentle soap to reduce the buildup of dead skin and oil. If patients have eczema or psoriasis on other parts of the body, it may affect their scalp and lead to dandruff as well. A dermatologist can help determine how to treat it.
