I just want to add the density and thicker of my eyebrows without changing size, length and width. Aftter that, I did my research about eyebrow transplant, some say that the eyebrow transplant can damage the natural follicle during making place for insertion and the original hair of eyebrow will die and not grow back again, which I guess it considered as a shockloss transplanted area.So i have question that my original follicle will be dead or not after the transplanted because the need for my operation is to make them thick, without losing the original eyebrows. How often and How many risk or probabilities that I am taking for this side effect. Do you have any prevent for this?
