Update on Frontal Fibrosing Alopecia

Area of Science:

• Dermatology
• Trichology

Background:

• Frontal fibrosing alopecia (FFA) is an acquired scarring alopecia characterized by hairline recession and eyebrow loss.
• Initially believed to be hormonally driven, cases in diverse populations challenge this theory.
• FFA shares histological similarities with lichen planopilaris, suggesting it may be a clinical variant.

Purpose of the Study:

• To review the latest data on the etiology, pathogenesis, clinical presentation, diagnosis, and treatment of FFA.
• To consolidate current understanding of this increasingly common condition.

Main Methods:

• Review of observational studies and existing literature on FFA.
• Analysis of reported treatment outcomes.

Main Results:

• 5-αreductase inhibitors and intralesional corticosteroids show the best reported results.
• Antimalarials and calcineurin inhibitors are also noted as potential treatments.
• No clinical trials have yet assessed FFA treatment efficacy.

Conclusions:

• FFA is a distinct clinical entity with evolving understanding of its origins.
• Current treatment strategies are based on observational data, highlighting the need for clinical trials.
• Further research into etiology and pathogenesis is warranted.
