It would do this by multiplying the hair a patient already has rather than using up the good hair that still exists on the patient's head. Hair cloning is done by taking stem cells, or dermal papilla cell, and cloning them in a laboratory setting. They are then multiplied and combined.

Earlier methods such as mini-grafting and micro-grafting broke up the follicular units. As a part of the hair transplant process with Follicular Unit Transplantation (FUT), a new microscope technique was used. It is called stereomicroscopic dissection. Then, you can use this number to figure up the grafts needed. Based on the fact that the average Caucasian male has a density of 2 hairs per millimeter, it can be assumed that the average density of hair is 1250 hairs per square inch. Figuring at an average of 2 hairs per follicular unit, it would take 625 follicular units per square inch. How to Find a Good Hair Transplant Surgeon There is no law in the US that requires a doctor to have any special credentials to perform hair transplant surgery, other than basic licensing as a physician. This leaves many potential candidates for the surgery in the dark. It is difficult to know the difference between a good hair transplant surgeon and an inexperienced one. Your transplants may start to bleed. It is important to clean your hair just as your doctor recommends after hair transplant surgery. You will be given a special shampoo to use and specific instructions on how and when to use it. It is necessary to clean gently but thoroughly. At first, you may find yourself rinsing your hair many times a day.
