In nature, some hair follicles stand alone while others are grouped together as neighbors or bundles of two, three and once in a while four hairs. These natural groupings are left intact in order that they may better thrive and look more natural in the recipient area. The use of high powered microscopes allows excess tissue from the FU’s while preserving the vital structures necessary for growth (pilosebacious gland and follicle), so they can be placed into 1/1.5 mm apart; a density and distribution appropriate for a mature individual’s hairline.
