Studysummary This review article examines the current understanding of frontal fibrosing alopecia, noting its prevalence in different demographics and the roles of genetic and environmental factors in its pathogenesis, while highlighting that treatment approaches remain varied and lack standardization. Our plain-language summary of this paper — not a Tressless recommendation.

The document provides a comprehensive analysis of Frontal Fibrosing Alopecia (FFA), a scarring hair loss condition primarily affecting postmenopausal women. It discusses the complex pathogenesis involving genetic, environmental, and inflammatory factors, and highlights the role of PPAR-y and mTOR. Diagnosis is based on clinical, trichoscopic, and histopathologic criteria, with new technologies like reflectance confocal microscopy being explored. Treatment lacks standardization, but topical and systemic therapies, including corticosteroids, calcineurin inhibitors, hydroxychloroquine, and 5-a-reductase inhibitors, show promise. A meta-analysis of 366 patients suggests dutasteride's potential effectiveness. The document emphasizes the need for non-invasive diagnostics and innovative treatments due to FFA's increasing prevalence and calls for further research to improve management strategies.
