Seborrheic Dermatitis: Symptoms, Causes, Treatment & Scalp Care

Seborrheic dermatitis is a common, chronic inflammatory skin condition that causes flaky, greasy, scaly patches and redness, most often on the scalp (dandruff), face, eyebrows, and chest. It affects millions of people and can be frustrating due to its recurring nature, but it is highly manageable with proper care. It is not contagious and is linked to yeast overgrowth, oil production, and immune response.

• Greasy or dry yellow-white scales on the scalp, eyebrows, or beard
• Red, inflamed patches on the face (nasolabial folds, forehead, ears)
• Itching, burning, or tightness
• Flaking that worsens in cold weather or with stress
• In infants: cradle cap (thick crusts on scalp)

Symptoms tend to flare and remit over time.

The exact cause is unknown but involves Malassezia yeast, excess sebum, and immune factors. Common triggers include stress, cold/dry weather, hormonal changes, and harsh skincare products. It is more common in people with oily skin or certain medical conditions.

Treatment focuses on reducing yeast and inflammation:

• Medicated shampoos (ketoconazole, zinc pyrithione, selenium sulfide) for scalp
• Topical antifungals or mild steroids for face and body
• Gentle daily cleansing with non-irritating products
• In stubborn cases: oral antifungals or light therapy

Consistency is key—many patients achieve good control with maintenance routines.

• Use gentle, fragrance-free cleansers and moisturizers
• Shampoo regularly with medicated products as recommended
• Manage stress and avoid known triggers
• Protect skin from extreme temperatures
• For sensitive skin: introduce new products slowly and patch-test

Seek care if symptoms persist despite over-the-counter care, worsen, or affect your quality of life. A dermatologist can confirm the diagnosis and create a personalized plan.

• Is seborrheic dermatitis curable? It is chronic but controllable with ongoing care.
• Can diet affect seborrheic dermatitis? Some find reducing sugar or yeast helps, but evidence is limited.
• Is it the same as dandruff? Dandruff is a mild form of scalp seborrheic dermatitis.
• Best treatment for facial seborrheic dermatitis? Topical antifungals and gentle skincare.
• Does it go away on its own? It can improve but often recurs without management.
