Hello , please go the reply  here as Dr.A.K.Mandal on 7th August as homoeopath ,from where my  name has been deleted  due to change of Photo.

First of all consult Homoeopathic physician for diagnosis of Skin problem whether it is dandruff or psoriasis. Both are curable with Homoeopathic treatment.

Diagnosis would be depending on checking ur scalp,to see how its visible.In psoriasis its plaques like(scaly),in normal Dandruff,either powdery dry or oily depenfing on ur scalp nature.Usually psoriasis 8ncreases in winter.But itching will b there in both cases,but more in psorias8s.As u said,already u have underwent T/t for Psoriasis,then now it might be recurrence.To assess well,its better to consult once.

as per your problem, i think there may be lake of scalp norishment in form of oiling. If there is dandruff then it may alter as per the season means in winter and monsoon... If it persist through out the year then it may be scalp exfoliation due to lake of scalp hygiene. need not to worry about it , both are curable.
