in my case the lateral slit produced bad results. the yield was low, and some of the very few grafts that grew were thin and wispy, almost invisible to the naked eye producing no cosmetic improvent. i have arround 4000 pics from the last ht (YES 4000 pics - 10 GB and many close ups) and i can show this anytime, also in several other spots, marks from the incisions are visible . Now i dont know the exact cause of this, but since i had other transplants before and since my last donor strip was taken above the previous (meaning at least same or better quality hairs) i whould be expecting the grafts that seem to grow to be at least the same in diameter as the previous (assuming they were transplanted exactly as extracted and havent been manipulated or splitted etc) i am at 14 months post op now. i think maybe the failure of my surgery maybe is not related to the lateral slits, but to other factors related to the donor management - meaning that i think that miscalculations regarding the laxity limit that might have been made, caused my scalp to stretch SO BADLY that probably have affected the blood circulation (since my scalp feeled like someone was pushing it backwards untill the 8th - 9th month) + serious donor complications that require 1 or even more additional corrective work, which after the latest bad experience i am really hesitant to undergo.
