You do not need a person whose only agenda is to sell you on getting hair transplant procedures done. 3. You should start to get concerned if your doctor has no specific good stories to tell about hair transplant surgery they have done. You need to see before and after photos. You need a way to contact former patients. 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. In fact, some people have been so disappointed and even angered about their results that they have filed class action lawsuits against hair transplant surgeons and clinics. There are several reasons they give for their dissatisfaction. 1. Underestimating Procedures. Certain surgeons and clinics underestimate the number of procedures necessary to achieve the desired effect. Men with this pattern of balding will have donor hair that survives the hair transplant process and flourishes long afterward. That is because a naturally-occurring enzyme in the body combines with testosterone to create a chemical called DHT. This chemical is responsible for the hair loss on the tops of men's heads when they have male pattern baldness. 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. These two groups add up to about 5% of the patients who have hair transplant surgery. The other 95% of patients have no problems with their tiny scars at all. The hair transplant doctors are able to keep the donor strips very thin. They also use a double layer closure method to help the skin heal properly.
