Androgenetic alopecia (AGA) is the most common type of hair loss both in male and female patients. As regards its etiopathology, it is postulated that hair follicles grow sensitive to androgens in persons who are genetically predisposed to it. In the pathomechanism of the disease, hair follicles undergo miniaturization.
The aim of the study was to evaluate the levels of selected hormones (sex hormones, adrenal and thyroid hormones), and the results of laboratory tests (iron metabolism) performed in a group of female patients with AGA in order to specify which of those tests should be taken during the diagnostic process in such patients.
Material and methods
. Test results and types of therapies have been analyzed for a group of 106 adult female patients (of different age) with female pattern hair loss (FPHL) of different duration. Selected hormone parameters have been analyzed as well as iron metabolism, BMI ( body mass index), and signs of androgenization in the patients’ histories (presence of menstrual disorders, hirsutism and acne). Additionally, their insulin levels were measured.
. The most common hormonal disorders in the study population involved increased concentrations of sex hormone binding globulin (SHBG) in 38.8%, decreased concentration of total testosterone in 25.4%, increased antibody titers against thyroid peroxidase (ATPO) in 17.3%, decreased concentrations of dihydroepiandrostendione (DHEAS) in 15.6%, and increased concentrations of insulin in 12.6%. Increased concentrations of free testosterone were only observed in 6.8 % of the study participants, and increased concentrations of cortisol were revealed in 6.7% of them. 40% of the patients complained about symptoms related to menstrual disorders, hirsutism and acne. Sex hormone concentrations did not correlate with the reported symptoms, and test results in that sub-group were not found to significantly differ from the rest of the patients who did not report signs of hyperandrogenism.
. In spite of the fact that nearly half of the patients reported symptoms which may be suggestive of hormonal disorders, no significant abnormalities were revealed in hormone tests.

Key words: androgenetic alopecia, hormones, female pattern hair loss
