A normal hair transplantation procedure involves the removal of donor strip of hair from the back of the head from where the follicular unit grafts are dissected beneath a microscope. These grafts are then preserved in saline and are then transplanted on a bald patch on the crown region of the scalp.
Given the time consuming and tedious nature of this procedure, a hair transplant surgeon is usually able to transplant only about 500 to 600 follicular unit grafts per day. Nonetheless, thanks to the recent hair transplant advances, this technique is usually replaced by the follicular unit extraction (FUE). The cost per graft of FUE is typically twice the expense of the regular follicular unit hair transplant procedure discussed above but it is comparatively more rapidly and minimally invasive.
Some hair transplant advances
In a common FUE procedure a tiny round punch is created in the donor area to directly extract 1, 2, three and 4 hair follicular unit grafts. The follicular units extracted utilizing this method is generally referred to as "blunt dissection" where a punch is made to envelope the complete follicular unit separating it from the surrounding soft tissues.
After the underlying follicular unit is separated from the surrounding tissues, it is simply extracted employing a small forceps. The tiny holes left behind immediately after the follicular unit extraction steadily heal more than the next handful of days and are not detectable to the naked eye after the patient's hair grows out. The healing time is much less than the donor strip extraction procedure.
While the FUE process has been adopted by most hair transplant clinics, the regular strip excision approach is nonetheless the most popular hair transplant process due to the fact it is more cost-effective than the FUE.
Furthermore, due to some latest hair transplant advances such as the use of trichophytic closure strategy, the linear donor scar developed by the strip excision process is now usually rendered practically undetectable to the naked eye. This advancement in the hair transplantation approach has produced FUE procedure reasonably much less appealing.
Hair transplantation investigation
In addition to the hair transplant advances in the transplantation procedures, a lot of research is also underway to clone the hair. If the hair transplantation study is profitable it will be achievable to make a number of copies of donor hair in the laboratory. The application of this method would be utilised in the form of hair transplantation. In the standard procedures, the biggest limitation is typically the donor which is not in a position to meet necessary density. However, hair cloning promises to overcome this issue by getting the amount of hair needed to be grown in a laboratory from a single donor hair and then implanting it into the scalp.
Hair transplantation investigation for cloning is very challenging and there are many hurdles that have to be overcome relating to the security and cosmetic characteristics of the cloned hair.
