Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concern.. As per your complain dry skin on head and face along with flaky skin around nose, scalp and chin seems to be due to Seborrheic Dermatitis and it can occur due to a number of causes like very dry and cold climate, stress, fungal infection while can be genetic in origin.. I would suggest you to consult a Dermatologist and get evaluated and he can do a clinical examination as well as can also do a microscopic examination of the flakes to confirm the diagnosis.. In case if Seborrheic Dematitis is confirmed you can be advised to use shampoo containing ketaconazole, salicylic acid, coal tar, zinc, selenium etc.. massaging the scalp with steroid lotion can be advised.. For face wash your face with salicylic acid containing mild facewash.. Keep the face clean and apply emollient facial cream.. You can be advised to apply antifungal cream like Ketoconazole and also Ciclopirox 1% creams but to be used under supervision of dermatologist.. You should do moderate sun exposure as fungal infection can heal when exposed to sun.. You should drink plenty of water to maintain turgor of skin.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
