Background/Aim Androgenetic alopecia (AGA) is the most common type of hair loss. Androgens and genetic factors are responsible for pathogenesis. Blood groups are genetic markers that are used to identify human gene variation. The aim of this study was to evaluate the blood group distribution in patients with AGA and to compare it with healthy population. Materials and Methods A total of 207 patients diagnosed with AGA in dermatology clinic and whose blood group records were available, between 2010 and 2019, were included in the study. Six hundred forty two healthy individuals who matched with the patient group in terms of age and sex, who attending to the family medicine outpatient clinic of our hospital in order to learn their blood groups were included as the control group. Results When the results were compared, no statistically significant difference was found between the two groups (P > .05). Conclusion We could not find any relationship between AGA and blood groups. However, in order to determine this relationship more clearly, further multicentre studies including more cases and investigating subgroups of the cases are needed.
