Seborrheic Dermatitis — Conditions

What is Seborrheic Dermatitis?

A chronic inflammatory skin condition affecting sebum-rich areas

Characterized by oily scales and redness on the scalp, nose folds, and eyebrow area, associated with Malassezia fungus.

Main causes & characteristics

Seborrheic dermatitis is a chronic inflammatory state that tends to occur on the scalp, around the nose, the eyebrows, and around the ears where sebaceous glands are developed, and it is understood to involve the resident fungus Malassezia, excess sebum, and an individual's skin reactivity together. Greasy yellow flakes, redness, and itching are characteristic, and it tends to flare and improve in cycles. It tends to worsen during seasonal changes, stress, lack of sleep, and heavy drinking.

How to manage

Gently tidying excess sebum and flakes with a low-irritation, mildly acidic cleanser, and using scalp products with ingredients known to help calm the skin's texture, is generally recommended. Avoiding hot-water washing and excessive scrubbing while also supporting the barrier with moisturizing is advisable. If symptoms are severe or persist for a long time, consulting a dermatologist is recommended.

Good to know alongside

Its appearance can overlap with dandruff, psoriasis, and atopic dermatitis, so distinguishing them is needed, and it is also discussed in connection with Malassezia folliculitis. Alcohol and high-sugar eating habits are cited as aggravating factors.

Everyday care tips

Getting enough sleep and managing stress can help lower the frequency of flares. Reduce overuse of hats and hair products and let the scalp breathe.
