[|AI|]  Hello, Thank you for posting on Chat Doctor. It seems you are suffering from Seborrhea dermatitis, which is an inflammation of sebaceous gland and secondary infected by fungus. I would recommend you a short course of oral antifungal Chat Doctor.  Use a medicated shampoo containing ketoconazole and alicyclic acid twice a week. Take antihistamines as required for itching. Avoid excessive use of hair oil. Hope this will take care of your query. Thank you
