Objective: To analyze the frequency of the types of alopecia in patients consulting at specialist hair clinics (SHC) and to assess for global variations. Methods: Multicenter retrospective study including data from patients evaluated at referral SHC in Europe, America, Africa and Australia. Results: A total of 2,835 patients (72.7% females and 27.3% males) with 3,133 diagnoses of alopecia were included (73% were non-cicatricial and 27% were cicatricial alopecias). In all, 57 different types of alopecia were characterized. The most frequent type was androgenetic alopecia (AGA) (37.7%), followed by alopecia areata (AA) (18.2%), telogen effluvium (TE) (11.3%), frontal fibrosing alopecia (FFA) (10.8%), lichen planopilaris (LPP) (7.6%), folliculitis decalvans (FD) (2.8%), discoid lupus (1.9%) and fibrosing alopecia in a pattern distribution (FAPD) (1.8%). There was a male predominance in patients with acne keloidalis nuchae, dissecting cellulitis and FD, and female predominance in traction alopecia, central centrifugal cicatricial alopecia, FFA, TE, FAPD and LPP. Conclusion: AGA followed by AA and TE were the most frequent cause of non-cicatricial alopecia, while FFA was the most frequent cause of cicatricial alopecia in all studied geographical areas.","https://refubium.fu-berlin.de/handle/fub188/28567||http://dx.doi.org/10.17169/refubium-28316","eng","600 Technik, Medizin, angewandte Wissenschaften::610 Medizin und Gesundheit::610 Medizin und Gesundheit","Hair diseases||Alopecia||Androgenetic alopecia||Alopecia areata||Frontal fibrosing alopecia||Telogen effluvium||Folliculitis decalvans||Lichen planopilaris||Epidemiology","Frequency of the Types of Alopecia at Twenty-Two Specialist Hair Clinics: A Multicenter Study","Wissenschaftlicher Artikel","open access","10.1159/000496708","Skin Appendage Disorders","5","Karger","315","309","31559256","5","2296-9195","2296-9160","Copyright applies in this work.","http://rightsstatements.org/vocab/InC/1.0/","Charité - Universitätsmedizin Berlin","Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG geförderten) Allianz- bzw.
