Which demographic is most commonly affected by seborrheic dermatitis?

Seborrheic dermatitis is a common skin condition that tends to manifest frequently in adolescents and young adults. This demographic is particularly susceptible due to hormonal changes that occur during puberty, which can increase oil production in the skin. This excess oil can contribute to the development of seborrheic dermatitis, causing red, flaky patches, and dandruff in the scalp area as well as on the face and other oily regions of the body.

While newborns can experience a similar condition known as cradle cap, which is a harmless form of seborrheic dermatitis, the majority of cases, particularly in more severe and persistent forms, are seen in adolescents and young adults. In older adults and seniors, the prevalence of this condition can decrease, although it can still appear, particularly in those with certain underlying health conditions or hormonal changes. Understanding this demographic trend can help practitioners recognize and treat seborrheic dermatitis effectively in their patients.
