Abstract

Abstract: Background: Hair‐ and scalp‐related disorders (HSRDs) encompass a wide range of conditions that affect people of all ages. Objective: To evaluate the workload and trends in HSRDs at an outpatient dermatological clinic in a tertiary medical centre over a 10‐year period. Methods: Medical records for HSRD visits to the outpatient dermatology clinic at the Sheba Medical Center, an Israeli tertiary care center, were reviewed between 1 January, 2010 and 31 December, 2020. Results: There were 10, 396 HSRD visits with a new‐to‐follow‐up visit ratio of 1:1.9. The annual number of HSRD visits, as well as their proportion out of all dermatological outpatient visits, have increased from 295 (1.24%) in 2010 to 1726 (9.44%) in 2020. The patients' mean age was 35.3 years (women 39.5 years, men 28.8 years), age range 1–87 years. Over the decade, there was a growing predominance of women with an average female‐to‐male ratio of 2:1. The winter season accounted for 28.7% of annual visits, followed by the autumn (25.6%), summer (24.3%) and spring (21.4%). The most prevalent HSRDs included androgenetic alopecia (30.6%), alopecia areata (19.3%), telogen effluvium (15.4%), non‐scarring folliculitis (15.4%), seborrheic dermatitis (14.9%), lichen planopilaris (7.1%) and folliculitis decalvans (6.6%). Androgenetic alopecia demonstrated the highest increase over the decade examined (from 17% to 32%). Conclusion: HSRDs account for a significant percentage of visits at a tertiary dermatology outpatient clinic. The number of HSRD visits has increased annually over the past decade. The recent advancement in diagnosis and treatment may account, at least in part, for the growing burden of HSRDs within dermatological ambulatory care.
