Psoriasis is a chronic inflammatory skin disease with multisystemic implications and genetic predisposition, which affects approximately 2 % of the general population. The scalp is one of the most common sites of involvement, affecting more than half of the patients suffering of psoriasis. Topical treatments are the mainstay of treatment for scalp psoriasis, with the active ingredients and also the vehicle relevant to efficacy and compliance.

We present the case of a 51-year-old female patient who has been referred to our clinic 6 months ago, for an eruption constituted by well-defined erythematous-scuamous plaques, intensely pruritic, located over the scalp, with an evolution period of 2 months. On the basis of clinical picture and histopathological findings the diagnosis of scalp psoriasis was established. The patient was treated with calcipotriol and betamethasone dipropionate in a gel applied once daily, with the complete resolution of scalp lesions in 8 days and mainstay of the results (last control visit at 4 months).
