Hi, You are suffering from oily dandruff with severe itching and hair fall. It most probably looks like ‘Seborrhoeic dermatitis’. You will need to first get your scalp examined by a Dermatologist and send the skin scrapings for examination. Also simultaneously you need to apply anti fungal lotion/ shampoo such as Nizaral. Oral antifungal medication can increase the effectiveness of topical lotions / shampoo. Your dermatologist can help you prescribing oral medications. If there are other factors like emotional problems, hard shampoos, exposure to severe cold, excessive intake of oily and sweet foods - influencing dandruff, it should also be dealt with. Avoid using combs used by other people especially, when a person is suffering dandruff. If you are suffering from dandruff and if you are using an anti dandruff shampoo, make sure you wash your comb every time after using the shampoo. A good hygiene and healthy hair care regime can keep away dandruff to a great extend .Shampoo at least once a week. While washing your hair, avoid the water from your hair dripping down your face as it may cause pimples. Do not allow your hair to remain wet for a long time.
