Scalp psoriasis: a review of current topical treatment options.

The scalp is the most common site of disease involvement at the onset and throughout the course of psoriasis. For many patients, psoriasis of the scalp is the most difficult aspect of their disease; yet, despite a wide range of therapy options and an extensive literature base, scalp psoriasis remains difficult to treat, highlighting a long-standing unmet need for the effective treatment of scalp psoriasis. A review of past and current medical literature reveals that a number of interesting therapeutic approaches have been used in the treatment of scalp psoriasis. The diverse and sometimes extreme therapeutic approaches, the marginal benefit of many topical agents, the paucity of controlled studies evaluating the efficacy of topical agents in the treatment of scalp psoriasis and the high level of patient dissatisfaction with currently available treatments for psoriasis all support the need for new, effective and well-tolerated treatment options for scalp psoriasis.
