Background Female pattern hair loss (FPHL), also known as female androgenic alopecia, is a common dermatological disorder with a multifactorial pathogenesis. Oxidative status has been implicated in the pathogenesis of several skin diseases, including FPHL. Aim This study was aimed to investigate the levels of oxidative stress biomarkers in patients with FPHL with varying severities. Patients and methods The study involved 56 patients with FPHL and 46 healthy controls. Diagnosis was based on clinical examination and trichoscopic evaluation. Patients were grouped into three subgroups as follows: mild, moderate, and extensive. Oxidative stress was examined by measuring plasma levels of catalase (CAT), superoxide dismutase, total antioxidant capacity, and malondialdehyde (MDA). Results Plasma levels of MDA in FPHL were significantly higher as compared with that of the controls, whereas activities of the antioxidant enzymes superoxide dismutase and CAT were lower. Moreover, total antioxidant capacity was also low in patients with FPHL as compared with that of the controls. Higher MDA levels in the extensive FPHL subgroup as compared with that of the mild and moderate subgroups were also observed. Furthermore, in the extensive FPHL subgroup, a significant negative correlation was observed between MDA and CAT levels. Conclusion The data suggest that oxidative stress plays a key role in FPHL progress, which accelerates hair loss by causing microinflammation and fibrosis. The recognition of the effect of androgens and associated factors on the hair follicle cycle is essential for the development of new and effective treatment methods and may be employed as a biomarker index to assess the disease’s activity and to monitor its treatment.
