What two distinct populations of hair are affected by shedding during the shock loss period?

Answer

The transplanted grafts themselves and the surrounding native hair

It is crucial to understand that shock loss is not limited solely to the newly placed follicular units. The mechanical stress and subsequent inflammation resulting from the harvesting and implantation procedures trigger a response in both populations of hair in the operative area. The surrounding existing or native hairs experience similar trauma-induced dormancy, leading to shedding. This dual effect is why thinning might be observed not only where the new plugs were placed but also in the adjacent area where existing hair resides, sometimes creating a temporary, diffuse appearance of thinning around the transplant zone.
