Seborrheic dermatitis, also called seborrhoeic eczema, usually affects areas where the skin is naturally oilier. Common sites are the scalp, eyebrows, sides of the nose, behind the ears and sometimes the chest.
What it can look like#
The skin may be red, flaky and itchy. On the scalp the scale is often more oily and yellowish than dry, fine dandruff. On the face it may look like irritation around the nose, eyebrows or ears.
How it differs from ordinary dry skin#
Dry skin is often more tight and fine-scaled. Seborrheic dermatitis is often greasier, redder and more clearly concentrated in the typical oily areas. That is why washing harder usually does not solve it.
What you can do at home#
Use a gentle but regular routine. Wash the scalp as needed, and use a suitable shampoo or wash product that you let sit for a short time before rinsing. On the face, choose a mild cleanser and a light moisturiser if the skin feels dry or tight.
Heavy oils and harsh scrubbing can make the skin more irritated. It is usually better to make one small change at a time and see what actually calms the skin.
When to seek care#
Seek care if the area becomes painful, crusted, weepy or rapidly more red, or if the rash is widespread or does not settle despite regular home care. Seek care also if you suspect psoriasis, a fungal infection or contact allergy.
