Dear Dr. Rassman,
How dense can hair transplant be done assuming that there are plenty of donor area with thick hair and the target area still has 50% density? Can hair transplant be done in-between existing hairs to make the hair thick again?
Tried Propecia but stopped after 2 days because of side effects. I appreciate your help on the matter.
You can transplant between existing hairs without difficulty, providing that the existing hairs are permanent and not miniaturized. I have seen patients receive very dense hair by transplanting between hairs that were previously transplanted.
