Seborrheic dermatitis is a chronic inflammatory skin condition that causes flaky, white to yellowish scales, redness, and itching. It most commonly affects oily areas such as the scalp, face (especially around the nose and eyebrows), ears, and chest. While not contagious, it can be persistent and requires regular management.

Symptoms vary by severity and location but typically include:

Flaky Patches – Greasy scales or flakes, especially on scalp, eyebrows, or chest.

Redness & Irritation – Inflamed, red skin beneath the flakes.

Itching – Itching or burning sensation in affected areas.

Scalp Build-Up – Thick crusts in severe scalp cases (cradle cap in infants).

Seborrheic dermatitis can affect people of all ages—from infants (cradle cap) to adults. It’s more common in men and individuals with oily skin, neurological disorders, or suppressed immune systems.
