I was watching several videos about the extraction process and I don't understand how it is possible to prevent the follicles from being cut during the extraction? Here are a few examples and as you can see in the first video at 0:59 (probably) and 1:07 (definitely), two follicles have disappeared. It is not clear if it is destroyed or if it is just hair that is cut off and the follicle remains in the skin, and the hair grows back in its original place. In the first video, 2 out of 10 follicles are gone, which means an 80% survival rate at the moment, which I consider very low.
Also, if the hair is implanted in an area with preexisting hair, the channels that open up can destroy the existing hair follicles. I'm right?
