More is better! This axiom serves as the foundation for modern hair transplantation and should always be referred to when making any decisions regarding hair restoration surgery.
Patients become the most confused when they go to different offices and are told radically different things. Often times a patient is told that he needs 1,000 or 2,000 grafts over the entire bald scalp area, giving the patient 16-20 grafts per square centimeter. They tell the patient that they voluntarily perform this low-density transplant for the patients benefit. The reason most often given is a supposed insufficiency of blood supply that could not nourish a large number of tightly placed grafts, and that if done the graft will die!
Make no mistake, the real reason they use this low concentration is because it is easier and faster and takes less skill and experience to perform a hair transplant. Often times other offices will show you before and after pictures showing you patients with high density transplants. What they don’t tell you is that they were taken after 3-4 surgeries in the same area.
The only way to get a natural looking transplant is to have the kind of density that is needed to look normal and not like you are going bald. The solution to this is to transplant 30 – 45 grafts per square centimeter or higher on average.
When this is done in one session, that area will be finished and not have any further need for transplants. This necessitates a high skill level, patience, and a desire to do great work. Along with the skill you need the proper equipment.
This is where the custom cut blade becomes very important. Because it is so sharp and small (0.7mm – 0.9mm) it allows you to put the slits very close together and still cause minimal trauma. And because they are so fine and small they also heal very quickly causing greater graft survival along with a much better result. Dense packing does take a lot more time and care but the results are well worth the effort. And unlike the case for the number of hairs, the fewer the surgeries, the better!
