Antidandruff shampoos containing antifungal agents such as ketoconazole or ciclopirox are sometimes helpful. Apart from that you need
topical and oral antibiotics, antihistamines, oral steroids and
topical tretinoin.
My sincere advice is to get it examined from a dermatologist. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor.
