Hello, Welcome to healthcaremagic From your description it could be either seborrhoeic dermatitis or scalp psoriasis. The chance of it being former is higher. Scalp psoriasis usually has well defined scaly patches over the scalp. Seborrhoeic dermatitis has greasy scales , a severe form of dandruff. The diagnosis can be confirmed by a dermatology consultation. Seborrhoeic dermatitis is a chronic condition, but very much controllable. It is caused by an yeast called malasezzia. This yeast is a normal resident of human body and once its colony increases you mount reaction against it causing dandruff. This yeast loves oil and therefore it is seen more in oily skinned. That is where hormones work. Androgens increase the production of oil from our sebaceous glands. Worsening of female pattern baldness is described in dandruff but dandruff per se won t cause hair fall. So the aim of any treatment is to bring down the colony of malasezzia. Anti-dandruff shampoo containing ketoconazole and ZPTO can be used 3 days a week for a month and maintain it atleast once a week to prevent yeast from multiplying. A course of oral antifungals like ketoconazole will help but you need a prescription for it. Avoid applying oil on the scalp. Hope this helped Take care
