Hair Transplantation Information
A common hair transplantation operation entails the removal of donor strip of hair from the back of the head from where the follicular unit grafts are dissected under a microscope. These grafts are then preserved in saline and are then transplanted on a bald patch on the crown area of the scalp.
Given the time consuming and cumbersome nature of this operation, a hair transplant surgeon is often able to transplant only about 500 to 600 follicular unit grafts per day. Though follicular unit extraction (FUE), thanks to recent hair transplant advances, often replaces this technique The cost per graft of FUE is typically twice the cost of the standard follicular unit hair transplant procedure discussed above but it is comparatively faster and minimally invasive.
A few hair transplant improvements
In a typical FUE procedure a small round punch is made in the donor area to directly extract 1, 2, 3 and 4 hair follicular unit grafts. The follicular units extracted using this process is typically referred to as “blunt dissection” where a punch is made to envelope the entire follicular unit separating it from the surrounding soft tissues.
Once the underlying follicular unit is separated from the surrounding tissues, it is easily extracted using a small forceps. The tiny holes left behind are eventually undetectable by the naked eye once they heal and allow the hair to regrow. The healing process duration is much less than the extraction procedure.
While the FUE procedure has been put into practice by most hair transplant treatment centers, the standard strip excision method is still the most well-liked hair transplant method because it is more efficient than the FUE.
Additionally, due to many recent hair transplant developments such as the usage of trichophytic closure technique, the linear donor scar made through the strip excision procedure is now often made almost undetectable to the naked eye . Due to this advancement, the FUE procedure has been rendered much less appealing.
Hair transplantation research
In addition to the hair transplant breakthroughs in the hair transplant procedures, a lot of research is also ongoing to clone the hair. If the hair transplantation research is successful it will be possible to make several copies of donor hair in the laboratory. The application of this technique would be used in the form of hair transplantation. In the traditional procedures, the biggest limitation is often the donor which is not able to meet required density. However, hair cloning promises to overcome this problem by having the amount of hair required to be grown in a laboratory from a single donor hair and then implanting it into the scalp.
Hair transplantation research for cloning is very difficult and there are many hurdles that have to be overcome regarding the safety and cosmetic characteristics of the cloned hair. Some hair transplantation research has also provided breakthrough for some hair loss medication like Dutasteride.
