A standard procedure for hair transplantation involves removing hair from the donor area at the back of the head 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 nature of the time-consuming and tedious procedure, a hair
transplant surgeon is often able to transplant only about 500 to 600
follicular units per day. However,
thanks to recent advances in hair transplantation, this technique is
often replaced by the follicular unit extraction (FUE). The
cost per graft of FUE is typically twice the cost of standard procedure
unit follicular hair transplant discussed above, but it is relatively
quick and minimally invasive.
Some advanced hair transplant
a typical procedure FUE punch small circle is done in the field of
donors to directly extract 1, 2, 3 and 4 hair transplant follicular
follicular units extracted using this process is usually called
"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 easy to remove using tweezers. The
small holes left after the follicular unit extraction gradually heal
over the next few days and are not detectable to the naked eye once the
patient's hair is down. The healing time is much less than the extraction procedure donor strip.
the FUE procedure has been adopted by most hair transplant clinics, the
standard strip method of excision is still the hair transplant
procedure the most popular because it is more economical than the FUE.
addition, due to some recent hair transplant such as the use of
technical trichophytic closure, linear donor scar created by the strip
excision procedure is now often rendered almost undetectable to the
naked eye. This advance in the art of hair transplant FUE procedure has been relatively less attractive.
Research hair transplant
Furthermore advances in hair transplant procedures transplantation, numerous studies are also underway to clone hair. If research on hair transplantation is successful, it will be possible to make several copies of donor hair in the laboratory. The application of this technique would be used as hair transplant. In traditional procedures, the biggest limitation is often the donor is not able to meet the required density. However,
hair cloning overcomes this problem by having the amount of hair to be
grown in a laboratory from a single donor hair and then implanted in the
on hair transplantation for cloning is very difficult and there are
many obstacles that have to be overcome regarding the safety and
cosmetic characteristics of the cloned hair. Some hair transplantation research has also provided some breakthrough drugs for hair loss as dutasteride.
