I agree, there should not be damage to existing hair follicles if the sites are created using high magnification.
However, for native hairs, it might be a different story. Shock loss is known to 'hit' native hairs hard which may lead to permanent or temporary loss of these hairs. If we believe there is a risk for shock loss we ask patients to have prior PRP treatments and use minoxidil and finasteride lotions to increase the hair strength.
