Hair Transplants

A common hair transplantation procedure requires 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.
The time consuming and tedious process enables a minimal amount, 500 to 600, of folicular grafts per day. However, thanks to the recent hair transplant advances, this technique is often replaced by the follicular unit extraction (FUE). 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.



Some hair transplant innovations



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 terminology for this process is generally known as "blunt dissection."



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 time is much less than the donor strip extraction procedure.



While the FUE procedure has been put into practice by most hair transplant treatment centers, the common strip excision method is still the most well-liked hair transplant method because it is more economical than the FUE.



Additionally, due to many recent hair transplant advancements much like the use of trichophytic closure technique, the linear donor scar made by the strip excision procedure is now often made almost undetectable to the naked eye . This advancement in the hair transplantation technique has made FUE procedure relatively less appealing.




Hair transplantation exploration



Besides the hair transplant developments in the hair transplant procedures, a lot of research is also underway 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.



The research underway for the cloning process is rather difficult. There are many hurdles that must be overcome pertaining to the safety and cosmetic characteristics of cloned hair. However, the research has already allowed for some significant breakthroughs in hair loss medication such as Dutasteride.
