Hello and welcome to healthcaremagic Seborrheic dermatitis or dandruff varies in severity in different individuals. The underlying cause is scalp inflammation and overgrowth of malasezzia furfur yeasts, however the exact role of the yeast is unknown. Nevertheless, antifungal shampoos and overnight lotions e.g ketoconazole, sertaconazole, oxiconazole, piroctone olamine, climbazole etc all have beneficial effects in seborrheic dermatitis. Since dandruff is bound to recur again, therefore it should be followed by once or twice weekly use of antidandruff shampoo for maintenance. However, if using a shampoo alone proves insufficient/inadequate, you would benefit from using a topical steroid solution at the scalp skin, once or twice daily along with an antidandruff shampoo. Steroid lotion can be stopped once your dandruff is relieved, thereafter you may continue with the shampoo for maintenance. regards
