Video from Ailesbury Clinic Dublin about FUE hair transplantation. Human hair grows in tiny bundles called follicular units. These units are seen on the surface of the scalp as a tiny group of hairs that appear to be growing together. The follicular unit of the adult human scalp consists of 1-4 terminal (full thickness) hair follicles. Follicular Unit Extraction (FUE) is a technique that involves using a small punch to extract follicular units from a patients donor area. Extreme care must be taken not to transect or severe the underlying hair follicle. Hair in the donor area must be cut very short for FUE.
In addition to the full terminal hairs, follicular units contain 1-2 fine vellus hairs, sebaceous (oil) glands, a small muscle, tiny nerves and blood vessels, and a fine band of collagen that surrounds the unit (the perifolliculum). The follicular unit is thus the hair bearing structure of the skin and should be kept intact to insure maximum growth.
