The scalp is the most frequently affected body region in psoriasis. Scalp Psoriasis can impair the quality of life greatly due to pruritus. This is however not usually investigated as a primary outcome of treatments. This study will investigate the effects of apremilast on the pruritus and quality of life and other patient reported outcomes in patients with scalp psoriasis.
