How common is scaly skin in seborrheic dermatitis?

Seborrheic dermatitis can cause flakes that look white, yellowish, or greasy, with itching and irritated skin underneath. The scalp may shed visible flakes, while the folds beside the nose, eyebrows, beard area, or behind the ears may feel sore or scaly. Symptoms can come and go, and stress, illness, cold weather, or harsh products may aggravate a flare. Similar scaling can occur with psoriasis, eczema, or a fungal infection, so location and examination help clarify the cause.

Wash gently with lukewarm water and use a mild, fragrance-free cleanser on the face. Avoid scratching and harsh scrubs, which can damage an already irritated barrier. A clinician or pharmacist may suggest a medicated shampoo or topical treatment for the affected area; use it as directed and keep products away from the eyes. Moisturiser can reduce tightness, but heavy or fragranced products may aggravate some people. If beard or scalp scale returns often, ask for a routine that fits your hair and skin type.

Arrange an assessment if the rash is painful, oozing, crusted, rapidly spreading, or affecting the eyelids. Seek help when flakes persist despite appropriate care, interfere with sleep, or lead to hair breakage or marked scalp inflammation. Fever, swelling, or pus needs prompt attention. A clinician can check for infection or another condition and select treatment for the exact site.

Ask which areas are affected, how often to use a medicated cleanser, whether your facial product is suitable, and how to protect the eyelids and ears during treatment. Ask what changes should prompt another review.
