Androgenetic alopecia (AGA) is the most prevalent type of hair loss in both men and women. As the name indicates, the role of androgens and genetic vulnerability predisposes to pattern hair loss. AGA is characterized by gradual hair follicular miniaturization, brought on by the actions of androgens on genetically sensitive hair follicles' epithelial cells in androgen-dependent regions. AGA in women is called female pattern hair loss (FPHL), which is characterized by a decrease in hair density in the central part of the scalp while the frontal hairline is typically well preserved. While histologically identical, male, and female pattern hair loss are separate clinical entities. There are many known and unknown factors that influence the development of AGA, its exact pathogenesis is unclear precisely. This article discusses the current understanding of the etiopathogenesis of AGA, clinical features diagnostic tests available, and its treatment options such as various topical agents, systemic agents, and procedural interventions.
