The baldness pattern of the candidate makes a crucial
assessment for the best technique of harvesting donor hair. The current baldness pattern is a signal of
future baldness and the extent of it. This is important because the hair
affected with genetic baldness carries it’s characteristics to the recipient
zone as well, and despite the expensive transplantation, it bears high risk of
persistent baldness if the donor hair is not selected carefully.
Hair Densitometry And
How Accurate Is it?
A densitometry is a principle to assess hair miniaturization
and Norwood classification that uses some specially designed gadgets to do so.
A hand held hair densitometer is used by many surgeons that purposefully use
magnification to allow counting of the existing hairs. It is applied to
selective regions of the hair, and the hair is clipped short for the
magnification to image the hair follicles. The densitometer does not give any
ascertained hair loss prediction, but with the condition of the hair
miniaturization experienced in advanced stages of baldness, surgeons can figure
out future hair loss and donor reserve quite well. However, with early stages
of baldness, it is very difficult to accurately tell of the donor reserve, the
hair loss has to stabilize at an advanced stage of the Norwood class.
What Does Texture And Thickness Of Hair Reveal
The texture and thickness of the donor hair is also
determined to assess how many hairs each graft should have to achieve the best
coverage. Hair pull test on unwashed hair is done by many surgeons to ascertain
the hair strength and whether or not they are miniaturizing. A section of hair
is gently held between the index finger and thumb and as gently pulled and if
any hair pulls out in the process, it validates active hair loss in the
candidate.
Early Stages Of Hair Loss Are Not Eligible For Hair Transplantation
The
early stages of baldness due to androgenic alopecia are uncertain to reveal the
extent of hair miniaturization and the donor reserve, especially in case of
women, wherein hair loss is largely diffusive.
This
is because, the early stages of baldness makes hair loss prediction difficult
to have a certain conclusion of its future variation. Choosing random hairs
from the back of the scalp is not obvious, since many hairs in there are prone
to androgenic inflammation as well. So it takes the baldness to stabilize and
stop at a certain pattern for at least 2years for surgeons to assess a more
obvious donor reserve.
Even
though the new principles of hair loss prediction like densitometry even scalp
biopsy are run to assess the donor dominant hairs from the recipient dominant
characteristic.
Surgeons have devised new and more precise instruments and
surgical principles that promise better potentials. These new advancements have
not only made hair restoration more far reaching than male pattern baldness.
Other hair loss problems such as scarring alopecia, diffusive hair loss
(commonly occurs in women) can be viably treated with substantial hair restoration possibilities.
