The whole hair transplant industry is based on these two techniques, some using lateral slit exclusively such as H&W, and some insist to use sagittal and sometimes lateral like SMG as i noticed... all what i know is with sagittal its more natural and doesnt require shaving and no risk of intersecting other natural hairs, however lateral its a technique of illusion, by implanting hair against the nature of exisiting hair to intersect the other hair to give a feeling of fullness. Some say sites with lateral slit... Maintaining a healthy blood circulation in the recipient area.This is done by limiting the depth of the incision in the recipient skin such that it does not affect the circulation of the skin. In the lateral slit technique the incision is shallower than with sagital incisions. Reducing compression of grafts, which occurs when many grafts are transplanted at high density. In traditional sagital (front to back) incisions the pressure that the grafts exert on the site walls of the incision are all added together by the pressures produced by its neighboring grafts. In the lateral slit technique the pressure is exerted in an up and down direction. In this plane there is free expansion into the area above the scalp, and the individual pressures executed by each graft do not affect the pressures executed by neighboring grafts. But in the other hand... I read that sagittal has advantages too... parallel incisions between existing hairs minimized the chance of severing existing hair follicles. Many also felt that since blood vessels in the scalp ran vertically that incisions made parallel to these vessels would severe fewer blood vessels and thus create less disruption to the scalp. Im kinda confused, pleas advice more. I think thats the ultimate secret of the industry.
