Hair transplant surgery is surely less painful than it was in earlier times when larger sections of scalp were excised. This involved more cutting to take out the donor hair and more cutting to insert the donor hair into the recipient site. Hair transplant surgery was a very painful procedure in the past. To understand how follicular units have affected hair transplant surgery practices, it is necessary to first understand what a follicular unit is. A follicular unit is a single entity that is made up of several parts. All these parts are necessary to the whole. The first part, and the one most people getting hair transplant surgery are interested in, is the hairs. Hair cloning promises to be a revolutionary procedure that would give people with little hair a chance to have hair transplant surgeries. 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. For example, you need to make sure you get enough blood flow during the night. You can do this by sleeping on pillows to elevate your head. Your usual pillows can be used, or you can buy wedge-shaped pillows made for this purpose. On the other hand, you do not want too much blood flow. You should get plenty of rest after your hair transplant surgery. Hair transplant procedures have changed in the decades since they were first done. The earlier methods of using hair plugs were not satisfactory. People looked like they had doll's heads, with hair sticking out of their hair in clumps. Now hair transplants are more natural looking because of a procedure called micro grafting. How Hair Is Inserted in Hair Transplant Surgery Hair transplant surgery begins, after anesthesia is applied, with removing donor tissue. Follicular units are then extracted from the tissue using a stereomicroscope. This is all done by skilled nurses and technicians. The insertion of the hair into the receptor sites comes later.
