Trichoscopy of Frontal Fibrosing Alopecia in Caucasians: A Review

Abstract

Background: Frontal fibrosing alopecia (FFA) is a scarring hair loss condition primarily affecting the frontotemporal hairline and often leading to partial or complete loss of eyebrows in a significant number of cases. It is characterized by slow progression and typically shows poor response to available treatments. Diagnosis relies on clinical, trichoscopic, and histopathological assessments, with specific criteria proposed by Vañó‐Galván et al. in 2018 [J Am Acad Dermatol. 2018;78(1):e21‐2]. Summary: This literature review examines trichoscopic observations of FFA in Caucasians, focusing on both scalp and eyebrow manifestations. A comprehensive search of the PubMed database from 2010 to 2023 yielded 6 relevant articles. Trichoscopic findings varied across studies but highlighted common features such as empty follicles, perifollicular erythema, follicular hyperkeratosis, and the presence of “lonely hair” on the scalp. Additional research is warranted to thoroughly characterize demographic traits and FFA peculiarities within the Caucasian population, given the limited existing data in the literature. Key Messages: Distinct trichoscopic features: trichoscopic examination of FFA among Caucasians reveals specific markers such as empty follicles, perifollicular erythema, and follicular hyperkeratosis, aiding in diagnosis and monitoring. Limited literature data: more investigation is needed to fully understand the demographic characteristics and FFA peculiarities among Caucasians, considering the scarcity of available data in existing literature.
