Seborrheic Dermatitis: Causes, Symptoms, Treatment, and Prevention Guide

Seborrheic dermatitis is a common chronic inflammatory skin condition that mainly affects areas rich in oil-producing glands. It often appears on the scalp, face, ears, eyebrows, chest, and sides of the nose. This condition causes redness, itching, greasy patches, and flaky scales, often mistaken for ordinary dandruff.

Although seborrheic dermatitis is not contagious or dangerous, it can be uncomfortable, persistent, and frustrating. Understanding its causes, symptoms, and treatment options can help manage flare-ups and improve skin health.

~What Is Seborrheic Dermatitis?

Seborrheic dermatitis, sometimes called seborrheic eczema, is a chronic skin disorder that leads to scaly patches, inflamed skin, and stubborn dandruff. It may come and go over time, with symptoms worsening during stress, cold weather, or hormonal changes.

In infants, seborrheic dermatitis is commonly known as cradle cap, causing thick, crusty scales on a baby’s scalp.

Common Areas Affected:

• Scalp

• Hairline

• Eyebrows

• Eyelids

• Sides of the nose

• Ears and behind ears

• Beard area

• Chest and upper back

• Skin folds
