Androgenetic alopecia (AGA) is an androgen‐dependent hereditary trait resulting in hair miniaturization. It is the most common type of alopecia in men and women. During the last years, multiple treatment modalities have been studied, but only topical minoxidil and finasteride have been approved by the US Food and Drug Administration. Microneedling (MN) is a minimally invasive technique that induces collagen formation, as well as growth factors production and neovascularization. Even though not many studies of MN in alopecia have been performed, it remains a favorable treatment modality; however, no standardized protocol for MN in hair loss has been proposed yet. Current evidence is not sufficient to allow a direct comparison with other therapies, but it shows promises to increase hair density, thickness, and quality of hair, especially when combined with other treatments or when used as a drug delivery system. This article aims to summarize the available literature regarding the use of MN alone or associated with other therapies for the treatment of androgenetic alopecia.
