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. A person with balding problems can gain a great deal of confidence by having hair transplant surgery. The procedure is a fairly easy one for the patient. However, there are some minor complications or side effects that sometimes come with the surgery. 1. Thinning. If you have hair transplant surgery, you might be alarmed if you notice that the hair you already did have is getting thinner. 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. A doctor who has done many successful hair transplant procedures will have a list of people willing to talk about their experience. You would have to go through many surgeries and your head may never look the same. This is why you should never accept any doctor's offer to do a few hair grafts and see how you like it before doing a full hair transplant surgery. Once you start, you are committed. 3. You need several days of rest afterward hair transplant surgery. If a person had this arrangement after a hair transplant and then shaved the micro grafts, the mini grafts would look decidedly unnatural. However, with the micro grafts on the leading edges, they blend in and give the hair fullness. They serve an important function. Previously, when hair plugs were used, doctors did the hair transplant surgeries much differently. These do not look as conspicuous as the hair plugs of earlier decades, but they do not look as natural as they can, either. Try to find a doctor that uses grafts that contain one to four hair follicles. These smaller grafts, also called follicular unit grafts, are ideal in restoring a receding hairline.
