Androgenetic alopecia updates: Pathophysiology, diagnosis and treatment

Abstract

Androgenetic alopecia (AGA) is a hereditary disorder characterized by the presence of hair follicles that exhibit sensitivity to androgens. The manifestations and progression of androgenetic alopecia are contingent upon the relationship between endocrine variables and genetic predisposition. Androgenetic alopecia is distinguished by the gradual reduction in size of hair follicles, resulting from the influence of androgens on the epithelial cells of hair follicles that are genetically predisposed and located in androgen-sensitive regions. There are varieties of medical, surgical and light-based treatment options available to slow or reverse the progression of AGA, some of these treatments are relatively new and still to be explored.
