INTRODUCTION

Seborrheic dermatitis (SD) is a chronic, relapsing inflammatory disorder affecting areas of the head and trunk where sebaceous glands are the most prominent and that evolves with flares and remission. SD is characterized by episodes of erythematous, scaly lesions of the scalp which can varies from mild to dense, diffuse, adherent flakes and pruritus. When mild scaling without visible inflammation is observed, SD is also named dandruff.
Topical therapies remain the mainstay of treatment for scalp seborrheic dermatitis (SSD). The two main classes of treatment for SD are topical corticosteroids and antifungal agents. Topical corticosteroids reduce mainly inflammation. However, prolonged treatment with topical steroids may result in adverse effects on the skin, such as atrophy and telangiectasia. Therefore, this class of therapy is mainly used to treat severe forms of SD.
