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.Take care and pls do keep me posted on how you are doing or if you have any additional doubts.
