Regarding "weighted" transplants, this was also the approach that Dr. Feller took with my second procedure second procedure -- which, granted, was different from the case of the patient who is the focus of this thread. Given that I part my hair on the left and will always do so, and therefore would benefit from maximum density on the left, Dr. Feller planted 2-hair grafts in the left "temple triangle" area, and single-hair grafts in the right (Dr. Feller, please confirm my facts here).
This photo, taken the evening after my procedure, seems to be an example of two aspects of how "weighting" worked for me.
* In the temple-triangle areas (top of the head, extending back from the left and right temples respectively), the greater density is not particularly evident when looking at the newly transplanted hair, nor in later photos of the top of the head, but in total work subtly to give the hair more bulk, based on the way I generally wear it. The result is a strategic "construction" of hair matched to my unique style and characteristics, but that looks natural.
* There is a small rectangular-looking area near the crown , into which Dr. Feller had opted not to transplant hair, given the particular hair loss pattern in that area. In the photo, the line between that area and the recipient area is highly pronounced, because my light hair was shaved down to my similarly light scalp, causing it to stand out vividly against the just-planted grafts near it. Again, in later photos, once the redness of the recipient area had subsided, there is no visible difference between the above two areas.
