I have seen some impressive results with Dermatch and Toppik, but you couldn't get that "wall of hair" look with it. It is essentially a two-dimensional illusion : once you lose too much hair you cease to be able to create the impression of a third dimension, and then it just looks like boot polish on your head. At least that was my experience.

This is pretty clearly a front partial piece, possibly quite narrow, but without a lace front or any graduation. It might even be undervented, which is very old technology now.
