A standard hair transplantation procedure requires the removal of donor strip of hair from the recession of the head from where the follicular watt 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 tedious nature of this procedure, a hair transplant surgeon is often able to transplant only about 500 to 600 follicular unit 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 criterion follicular unit byssus transfer procedure discussed above but it is comparatively faster and minimally invasive.
Some hair transplant advances
In a ideal FUE procedure a small round punch is made in the backer surroundings 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 faint forceps. The small holes left behind after the follicular unit descent gradually heal over the next scantiness days and are not detectable to the naked eye once the patient’s hair grows out. The healing time is much less than the donor strip extraction procedure.
While the FUE procedure has been adopted by most hair transplant clinics, the standard strip excision method is still the most popular hair transplant procedure because it is additional practical than the FUE.
Moreover, due to some recent capilliform transplant advances such as the use of trichophytic closure technique, the linear backer scar created by the strip excision procedure is now often rendered almost undetectable to the naked eye. This advancement in the hair transplantation technique has made FUE accouterment relatively less appealing.
Hair transplantation research
Besides the hair relocate advances in the transplantation procedures, a lot about research is including underway to clone the hair. If the hair transplantation research is successful it resolution be possible to acquire several copies of donor hair in the laboratory. The blank 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 besides provided breakthrough for some hair ruin medication like Dutasteride.
