Male androgenetic alopecia

Male androgenetic alopecia (MAA) is quite common and worsens with age, with significant impact on quality of life, and is increasingly a reason for consultation with a dermatologist. The etiopathogenesis of MAA is multifactorial and genetic and hormonal influences stand out. MAA starts with the process of follicular miniaturization in diverse phenotypic patterns. The diagnosis of MAA is basically clinical and currently corroborated by well-established trichoscopic findings. Despite this, therapeutic options are limited, especially when one considers medications with a high level of scientific evidence. This review aims to help the general dermatologist towards a better understanding of MAA providing a basis for good individualized and judicious therapeutic decisions.
