The epidermis absorbs water during a shower and can swell giving the appearance of elevated white pieces of tissue. This epidermis sheds with the scab in 7-10 days and the result is a smooth flat scalp post op without elevation or pitting.
Scarring from FUE is equal to the perimeter of the punch multiplied by the # of grafts. Compared to strip there is actually more scar tissue. As opposed to strip, where there is concentrated linear scarring, FUE, even with more scar tissue, is diffused over a larger area and less, if at all, noticeable.
I have used the "lateral" incision exclusively for a year and a half and find that I can control the angle better, match the size of the incision to the graft better (with 10 blade sizes at 0.1mm increments), limit the depth of incisions, and pack more densely.
I am not recommended on this site because I choose not to advertise here. I withdrew one year ago. There are some physicians on this site with which I choose not to be associated.
