Which instruction by the nurse for parents of an infant with areas of scaly skin on their scalp, also known as cradle cap is accurate?

A. Using a soft-bristled brush to gently loosen the scales and rinse them off is the recommended approach for cradle cap (seborrheic dermatitis of infancy). Parents can also apply a small amount of baby oil or mineral oil to soften the scales before brushing. This method is gentle, safe, and effective. B. Skipping hair washing may actually worsen cradle cap, since regular gentle shampooing helps remove excess oils and prevent buildup of scales. C. Rubbing lemon juice on the scalp can cause skin irritation and is not recommended in infants. D. Applying adult-strength dandruff shampoo is unsafe for infants due to the harsh chemicals it contains. Only mild baby shampoos or pediatrician-recommended medicated shampoos should be used if needed.
