Study of the Characteristics of Pruritus in Patients With Frontal Fibrosing Alopecia or Lichen Planus Pilaris

Study Overview
=================
Brief Summary
-----------------
The prevalence of pruritus has been studied in frontal fibrosis alopecia (FFA) and lichen planus pilaris (LPP), but there are no studies evaluating the characteristics of pruritus, the correlation between pruritus and disease activity, and its impact on quality of life. The knowledge of the characteristics of pruritus, of the link disease activity - pruritus, and its impact on the quality of life could allow us to modify the management of the patient (modification or intensification of therapy, close monitoring...)
