The following is a summary of “Comparison of demographics and comorbidities of female pattern hair loss according to the clinical subtype and stage,” published in the October 01, 2022 issue of Dermatology by Özkoca, et al.


There was conflicting information in the literature on the frequency of each subtype of female pattern hair loss, and the subtypes had not been compared to one another in terms of their epidemiologic traits and connections to comorbid disorders. For a study, researchers sought to ascertain the prevalence and relationship of each subtype with comorbidities and the association of clinical stage with age and comorbid disorders.

The study included individuals with a confirmed female pattern hair loss diagnosis and was prospective and cross-sectional. For each patient, the following information was recorded: age, age at the time of diagnosis, family history of androgenetic alopecia, clinical subtype, clinical stage, and concomitant diseases. The IBM SPSS version 21 was utilized for the statistical analysis.

Age, menopause, and hypertension were all associated with advanced female pattern hair loss stages. Early phases of acne vulgaris were more common. The Ludwig and Hamilton subtypes were more likely to experience hirsutism and acne vulgaris. In the Ludwig subtype, hypertension occurred more frequently.

They used the correlation between comorbid diseases and stage in particular categories to help diagnose comorbid diseases that had not yet been identified.
