The invention belongs to the technical field of hair transplantation, and particularly relates to a dot-matrix high-density type hair follicle transplantation method achieved under a PM+FUE omnidirectional mirror. The method comprises the steps of hair follicle detecting, angle customizing, hair follicle extracting, hair follicle separating, hair follicle planting and caring after planting. According to the hair follicle transplantation method, the transplantation embryo processing loss rate is low, the hair follicle survival rate is high, the hair density can be recovered to the normal hair density (100-150 pieces per square meter) through one time of surgical transplantation for the alopecia types from the stage I to the stage IV, new hair grows uniformly and naturally, and the defects that in a traditional single small-area transplantation method, the alopecia region area is increased, and the pressing effect is generated on growth of the new hair are overcome.
