Frontal fibrosing alopecia demographics: a survey of 29 patients.

Frontal fibrosing alopecia (FFA) is a form of scarring alopecia whose diagnosis is increasing globally. Although its etiology is unknown, FFA is thought to be a clinical subset of lichen planopilaris (LPP) that primarily affects postmenopausal women. Patients diagnosed with FFA between January 2006 and December 2013 at clinics of the Washington University Division of Dermatology (St. Louis, Missouri) were studied using patient surveys and chart notes to assess demographics, clinical features, medical history, and treatment. Twenty-nine patients were enrolled in the study, including 28 women and 1 man. The average age of disease onset was 55.4 years (range, 29-75 years). Many patients (55%) had a history of autoimmune diseases, including hypothyroidism (35%), mucocutaneous lichen planus (28%), psoriasis (7%), vitiligo (3%), systemic lupus erythematosus (3%), iritis (3%), Sjögren syndrome (3%), and ulcerative colitis (3%). Patients often identified a stressful inciting event prior to onset of hair loss. Patients tried an average of 3 different treatments for hair loss, with topical and intralesional steroids, hydroxychloroquine, topical calcineurin inhibitors, and excimer laser therapy being the most efficacious at limiting hair loss.
