"Fuchs’ team devised a strategy for labeling the bulge stem cells with a green fluorescent protein, allowing the group to study the behavior of the cells in vivo and to use fluorescence-activated cell sorting technology to purify the cells and grow them in culture.
They observed that a few of the bulge cells were “activated” at the start of each hair cycle, and that many were activated in response to a wound at the skin surface. The investigators also grafted cultured bulge cells onto nude mice (mice that lack hair follicles) and observed tufts of hair at the graft. "
If i’m reading it correctly, this supports follica’s method.
Plucking hair causes the follicle to immediatley go to the anagen phase (should also apply to vellus hair). So theoratically, plucking vellus (minitaurized) hair on temples followed by gentle abrasion of the area maybe beneficial.
