ABSTRACTAndrogenetic alopecia (AGA) is characterized by a progressive miniaturization without scars of the hair follicle with a patterned distribution in predisposed men and women. It is one of the most common causes of hair consultation. The etiopathogenesis is based on a progressive miniaturization of the hair follicle that leads to the hairy transformation of the terminal hair and is mediated genetically and by androgenic stimulation. There are specific trichoscopic data to facilitate its diagnosis. The goal of treatment is to avoid the miniaturization process and, if possible, reverse it. It must be individualized for each patient and depends on several factors, including efficacy, feasibility, risks and also costs since it is for life. Existing and some emerging therapies such as oral minoxidil, dutasteride, platelet-rich-plasma (PRP), cortexolone 17 α-propionate, spironolactone, cyproterone acetate, flutamide, bicalutamide, activators of the Wnt/β-catenin pathway and microneedling are analyzed in order to offer personalized treatments that improve the quality of life of patients
