Which condition presents with yellow or oily flakes on the scalp?

Seborrheic dermatitis is characterized by yellow or oily flakes on the scalp. This condition involves an inflammatory response, often influenced by factors such as oil production and the presence of a specific type of fungus that thrives in oily areas of the body. The flakes are typically larger and more greasy compared to those seen in other scalp conditions, making them distinctive. Seborrheic dermatitis can also present with redness and irritation on the scalp, often affecting regions where oil glands are more concentrated. This makes it different from conditions like dandruff, which usually produces dry, white flakes. The oily texture and yellow coloration of the flakes are key features that aid in identifying seborrheic dermatitis specifically.
