Scalp psoriasis with increased hair density.

Psoriasis is a chronic autoimmune skin disease that commonly affects the scalp. Psoriatic lesions on the scalp typically result in alopecia, possibly due to a higher proportion of hairs in the catagen and telogen stages. Involvement of the scalp in psoriasis can be problematic for the patient's quality of life as well as the clinician treating the condition. Here, we present an unusual case of scalp psoriasis presenting with increased hair density in the involved area that was resistant to topical steroids.
