A large percentage of men have balding issues. In fact, 50% of American men that are 50 years old or older are dealing with some amount of hair loss. Hair problems in today's society beg to be conquered. Some do it by shaving their heads completely. Others take the exact opposite route and have hair transplant surgery. The research cannot be done as to whether these hairs can safely and effectively be transplanted onto a person's scalp yet. First, they cloning process will have to be completely perfected. Only then can the hair transplant trials begin. More research needs to be done to find out which hair cells can be used for hair cloning and then hair transplant procedures. When a young man gets a hair transplant procedure, it can avert many problems with low self esteem and lack of self confidence. With older men, these attitudes are already ingrained so that it takes some doing to change them. If the hair restoration is started early enough, the young patient need never feel the stigma of being bald for very long at all. The follicular unit is a living unit with muscle, nerves and blood vessels that are all tiny enough to fit into this small package. The unit is set off by a band of collagen that holds it together. If you look under a microscope at a scalp, you can see follicular units growing in just this way. The idea of bringing this information into hair transplant procedures led to innovative surgical methods. The surgical team takes care to get every hair transplant graft into the receptor sites as they have been laid out. They waste no time, though, because the small grafts are vulnerable when their follicles are outside of the skin. The goal is to get the grafts in as quickly as possible while staying true to the design. 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. To get 25% of that, you would need 156 follicular units per square inch.
