The basic surgical plan for hair restoration is that the
candidate’s own existing hair is relocated to bald zones. Surgical planning of
modern hair transplantation has first of all developed the follicular grafting
strategy. In this strategy, the naturally occurring groups of hair are selected
in 2, 3, 4 and 5 hairs for each graft as the hair is plucked from the back of
the scalp with a thin sheath of fatty tissue. This technique replaces the old
methods wherein 1hair graft consisted of 7-12hairs making unnatural looking
hair plugs.
The hair grafts can be harvested by two methods.

Follicular Unit Transplant Strip
Procedure (FUT)
A strip of skin can be removed from the back of the scalp which
would contain the hair follicles stuck in it, in the procedure termed as
Follicular Unit Transplantation. The skin is dissected under a microscope to
separate the hair grafts. One 20cm strip of skin can commonly contain 1,500 to
2,000 hair follicular units. The area of the scalp from where the skin strip is
removed, leaving an open wound which is closed and sutured into a fine linear
scar that may be hidden underneath upper layers of hair. However, with poor
planning of either the strip excision, wound closure and suturing can leave a
more prominent permanent scar.
Individual hair grafts are extracted one at a time through a long
strenuous process. This surgical option eliminates the need to remove any skin
strip or skin cutting, with resultant potentials of no permanent scarring. The
procedure is also minimally invasive with very less downtime and surgical
fatigue. However, the surgical planning of this method is a crucial factor, as
the one at a time graft extraction exposes the hair grafts to stay out of the
body for longer period jeopardizing graft survival after the transplantation.
For accommodating
the hair relocation on the barren zones, a person requires more than a sufficient
donor reserve (enough hair at the back of the scalp). This is also beneficial for maintaining an
even density all through the scalp area. However there are set of many other
factors which qualify the eligibility of a patient with the best potential
credits for undertaking this surgery.
Assessing the baldness pattern of the candidates is required to
understand the best technique possible for harvesting donor reserve hair, which
is usually located at the back of the head.
The faster you get to realize that the future baldness possibilities are
well understood by glancing at the pattern of the current baldness pattern of
the candidate.
The hair which is already affected by the genetic baldness beholds
the characteristics of the recipient zone, which may come out gradually even
after treatment. Infact, even if the transplantation is expensive, but taken
from the affected donor region, the risk of persistent baldness still exists.
Proper assessment of the thickness and the healthy texture of the
donor hair is required to understand the number of grafts required to achieve
the best area coverage of the scalp.
