Which of the following statements is true regarding seborrheic dermatitis?

Seborrheic dermatitis is a common skin condition that primarily affects the scalp and face, often leading to flaking and redness. The statement indicating that it can cause dandruff is accurate because seborrheic dermatitis is one of the most frequent causes of dandruff, characterized by the presence of dry, white flakes of skin on the scalp. This condition can also manifest in other areas, such as the eyebrows and sides of the nose, where oil-producing glands are prominent.

The nature of seborrheic dermatitis makes it a chronic condition that may require ongoing management rather than a one-time cure. While treatments such as medicated shampoos or topical lotions can help alleviate symptoms, claim that it can be cured completely with a single treatment is misleading. Additionally, seborrheic dermatitis is not specific to any age group, thus asserting that it only affects adolescents is incorrect. It can affect individuals of all ages, including infants and adults. Lastly, it is not contagious, as it does not spread from person to person, focusing instead on individual factors such as skin type and the presence of certain microorganisms in the skin.
