Frontal Fibrosing Alopecia: A Descriptive Cross-Sectional Study Of 711 Cases In Female Patients From The Uk

Frontal fibrosing alopecia (FFA) is an inflammatory primary scarring alopecia of uncertain aetiology that represents a variant of lichen planopilaris. It predominantly, although not exclusively, affects post-menopausal women. Its pathogenesis is characterised by immune-mediated follicular destruction at the level of the hair bulge, which leads to a clinical phenotype of progressive fronto-temporal hair and eyebrow loss that is often preceded by widespread body hair loss.
