Dense Packing Limits?

I am a 26 year old male, who has had two hair transplants in my frontal area. The density of hair in my transplanted regions is much lower than that of my natural hair, and hence looks a bit unsightly. I want to know if there is a limit to the number of FU grafts one can transplant in order to improve density. If so, what are the dangers of exceeding this limit?

The normal hair densities of non-transplanted hair are measured at 193 hairs per cm squared (97 follicular units per cm square). A transplant doctor can put in densities of half of that in a single session. If you have thinning hair, then your density is not up to a level adequate to appear full. There are no inherent dangers in dense packing the hair in a transplant surgery provided that the doctor’s team is able to do it.

Dense packing, a technique we defined in 1993, makes for less surgeries and more fullness. If the wounds are over a particular size (more than 1.7mm each) then the risks start impacting the patient, for example, with regard to blood supply. If the wounds are smaller than 1.7mm, then the risks of dense packing of the grafts all but go away. We use wound sizes of about 1mm (the size of the wounds vary with each patient). The smaller the wounds, the faster the healing. Healing in this context means that the wounds on the skin become almost impossible to see, something that usually takes a day or two on most of our patients. Wounds greater than 1.7 mm, tend to show for longer periods. Some transplant patients in the old days saw wounds measuring 3-4 mm each (the old plugs), and they were visible for weeks after the surgery.
