I'm trying to understand as much as possible about strip scar camouflaging, since I have three scars I want Dr Cole to hide starting early next year. This website has been very informative. I now understand (correct me if I'm wrong) that transplanting hair into the scar not only helps hide it because the hair helps blend it in, but also because the blood supply the transplanted hair brings causes the scar color to more closely match the surrounding skin. I also understand that the best approach to filling in the scar is not to densely pack it in a single session, but rather to take several small-scale passes. I do, however, still have questions.
1. I know that the minimum goal is simply camouflaging the scar(s), but is it possible one could go further and - taking several passes - reach a density comparable to that of the surrounding scalp? Or at least close enough that a very closely trimmed head would not reveal the scar?
2. Does the yield percentage of a session tend to decrease with each subsequent session? Meaning, if I got an 85% yield with a first pass, is there reason to think I will get a lower yield from the second session, and an even lower yield with a third? Or, assuming the sessions are conservative, should the expected yield remain the same despite the fact that hair is being tranplanted into a scar where there is already growing hair? OR, might subsequent sessions give a higher yield than the first because there is hair growing (and therefore a greater supply of blood to the scar)?
