If your plugs are smaller, he may just want to add some new donor hair to lessen the effect of the doll head look. If cost is an issue with you, discuss it with your surgeon. Cost is a very real problem for many who want to have bad hair transplants fixed. It may be more expensive to do the correction than an original surgery would cost. You should be suspicious if you are shown less than a dozen or so sets of pictures. This may mean the doctor does not have much experience to brag about. The pictures should be of good quality so that you can really see what kind of job was done. Next, ask for names and phone numbers of patients the surgeon has treated. After their trials, they got the answer: the hair follicles themselves made the difference in the life of the hair and not where they were placed on the scalp. They termed this phenomenon Donor Dominance. Hair transplant surgery was on the horizon. Doctors started doing hair transplant procedures immediately. The surgeon must have an eye for detail to properly set the receptor sites. He must also be very artistic to achieve a natural look, especially at the hairline. The direction the hair grows, both on the front of the head and at the crown, are very important, too. The doctor must make the condition of the newly placed hair look like the patient's own natural scalp hair. Figuring at an average of 2 hairs per follicular unit, it would take 625 follicular units per square inch. To get 25% of that, you would need 156 follicular units per square inch. All that remains is to measure your balding area and multiply the number of square inches by 156. When you know what number of grafts to expect during your hair transplant surgery, you will be a savvy consumer. As a part of the hair transplant process with Follicular Unit Transplantation (FUT), a new microscope technique was used. It is called stereomicroscopic dissection. This means that the follicular units are carefully taken out of the donor tissue and kept individually intact. When doctors use hair transplant procedures with FUT, they do not have to use quite as large of a donor site.
