Q: When a second hair transplant is performed, should there be a second incision or should it be incorporated into the first? – D.V., Inwood, N.Y.

A: It is a very common practice to make a second separate scar in the second hair restoration procedure. This is done to maximize the hair in the second session, and it is technically the easiest to perform. If you incorporate the old scar in the new incision, there will obviously be less hair. As long as the upper incision is still in the permanent zone, the hair quality will be good.
