FUE, also known as Follicular Unit Extraction OR Follicular Unit Excision, is a hair transplant procedure in which the hair follicles or hair follicular units are individually removed from the donor area one by one. The follicles naturally occur in groups of 1-4 hairs in the donor area of the scalp. FUE can be performed by a manual, motorized or automated method depending on the individual patient. The excision method utilized varies based on the characteristics of the hair follicles such as hair shaft thickness, curliness, exit angle, etc.
