Male androgenetic alopecia is defined as the decrease in the amount and volume of hair that occurs slowly and progressively with replacement of terminal hair by hairy hair, also called follicular miniaturization, which is produced by the binding of dihydrotestosterone to the androgenic receptor in genetically predisposed hair follicles, shortening the anagen phase of hair growth. Given the clinical importance and psychosocial repercussions of patients suffering from this disease gives way to an important field of study that has managed over the years to find clinical and surgical solutions to improve the quality of life of patients who suffer from it, going through hair implant techniques such as follicular unit strip surgery to more recent techniques such as follicular unit extraction - FUE, with which the follicles of the donor area are extracted in an individual way without the need for stitches and without leaving visible scars, these being practically imperceptible. The grafts are carefully introduced by microincisions in the alopecic areas, or of scarce hair, that would evolve towards baldness. This case report and literature review article analyzes the current hair transplant procedure with follicular units under the follicular unit extraction technique, presenting the results of the clinical case of a patient suffering from androgenetic alopecia; where satisfactory aesthetic results are evidenced in a period of time of 12 months, and significant changes are described with their respective graphic illustration of evolution. Concluding that, the micro hair graft under the follicular unit extraction technique is a total solution with natural results that generate patient satisfaction.
