Seborrhoeic dermatitis

Seborrhoeic dermatitis is an inflammatory skin condition affecting areas with many oil-producing glands, such as the scalp, eyebrows, sides of the nose and chest. It can cause flaking, itching and changes in skin colour. Dandruff may be part of the picture, but inflammation can extend beyond the scalp.

Is it caused by poor hygiene?

No. Scrubbing harder is unlikely to solve the problem and may add irritation. The condition can recur even with regular washing. Other skin conditions, including psoriasis and contact dermatitis, can look similar, so persistent symptoms may need examination.

Tell the clinician which areas are affected and whether the skin is oily, dry, sore or crusted. Mention new products and previous treatments. Photographs during a flare may be helpful if the appearance changes before the appointment.

How is it managed?

A doctor or pharmacist can advise on suitable skin and scalp care. Treatment depends on the site and severity; a product appropriate for the scalp may not suit the eyelids or other sensitive skin. Follow directions rather than using a stronger or more frequent application because the condition is recurring.

Ask whether you need a maintenance plan and what to do at the first sign of a flare. If the diagnosis is uncertain or treatment causes irritation, arrange review. Repeatedly switching between products can make it difficult to identify what is helping and what is worsening the skin.

When should I see a doctor?

Review is useful if symptoms interfere with sleep, work or confidence, or if they do not improve with appropriate care. Increasing pain, discharge, warmth or fever may indicate infection and needs prompt assessment. Telehealth can help review the pattern and previous care, but widespread, severe or unfamiliar skin changes may require an in-person examination.
