another factor to consider is dense packing. in a single patient case a density of 10 follicular units per sq. cm, 20 follicular units per sq. cm, 30 fu per sq. cm, and 40 follicualr units per sq cm were compared for yield. the 10 fu/sq. cm group had a yeild of 97.5%, the 20 per sq cm yeild was 92%, the 30 fu per sq. cm was 72% and the 40 fu per sq. cm yeild was 78%. this does not mean that the hairs which did not grow are dead it means that they did not grow during this study. they may have been resting or in telogen and this can be expected. it may be that the higher densities had a more representative populatioin of the donor area and the lower densities contain more anagen hairs. of course one cannot make generalizations from a single patient study.

Good results take time.

It is difficult to do dense packing on a NW 6. It is simply supply and demand. Very good candidates are NW 2As, 3As, and 4As (no crown loss).
What is your Norwood class??

Densities of 60 - 80 FU/cm2 are a good goal for frontal loss. This is being achieved over multiple passes with FIT and strip.

There is a concern about yeld and consistency with ultra dense packing in one pass.
