Seborrheic dermatitis affects which age groups?

• A. Only infants
• B. Infants and adolescents
• C. Adults
• D. Only adolescents

Answer: (B)

Seborrheic dermatitis shows up most in two pediatric life stages when oil gland activity is high: infancy and adolescence. In infants, cradle cap appears because the immature sebaceous glands and lingering maternal hormones lead to greasy scalp scales. In adolescence, puberty drives increased androgen production, boosting sebum and oilier skin, which predisposes to inflammatory, flaky patches on the scalp and other oily areas. While adults can be affected too, the exam-focused pattern centers on these two pediatric periods—the combination of infancy and adolescence helps explain why this choice is the best fit.
