Hello,
I think the doctor is talking about seborrehic dermatitis which is also called adult
cradle cap. You can treat flaking and dryness with over-the-counter
dandruff or medicated shampoos. Shampoo the hair vigorously and frequently (preferably daily). Active ingredients in these shampoos include salicylic acid, coal tar, zinc, resorcin, ketoconazole, or selenium.
If the symptoms persist, then it would be best to get it confirmed from a dermatologist.
Hope it helps.
