| Hair transplantation provides natural and
undetectable results. Just like your old hair, you can dye, perm, and
cut your transplanted hair with no worries. This website is provided to
help educate you about the hair transplant procedure, and how it may be
one of the best decisions you've ever made.
Hair transplants today look better than they did just a few years
ago. That's because surgeons have learned exactly how hair normally
grows. And they're now able to re-create natural patterns, for a
good-looking head of hair.
| No matter which type of
graft is utilized, the basics of hair transplantation are the
same. I will attempt to describe these basics along with the most
commonly used techniques. In order to understand hair
transplantation, it is necessary to understand the concept of
donor dominance
A scalp may be divided roughly into two separate areas. One is
the area susceptible to balding and the other, of course, is the
area not. The horseshoe fringe of hair left behind on a bald
man’s scalp is the area from which hair can be safely donated.
Hair transplanted from this area of the scalp will not be
susceptible to balding even when it is placed right in the middle
of the bald scalp. This new hair maintains the same
characteristics of the hair left behind in the donor area no
matter where it is transplanted to the scalp. This is what is
meant by donor dominance.

| Multiple methods may be
used to harvest this donor hair. In the early days of hair
transplantation, the hair was removed in 4 mm plugs about the size
of a pencil eraser. Multiple plugs were removed simultaneously and
the area was allowed to heal in by itself. Although the healing
areas were messy the first week because of the weeping from the
open wound, the areas tended to heal well. The primary problem was
the cobblestone scar pattern left behind. Eventually the plugs
were taken out in rows so that the edges could be sewn together. |

Figure 4-3. Transplants were originally performed by removing 4
mm plugs from the shaved donor area and then transferring them
into 4 mm holes in the recipient area.
|
This led to the idea of
excising strips of tissue rather than plugs. The open area left by
the strip was more easily
sutured together. As the grafts that were transplanted became
smaller, physicians began to use multi-bladed scalpels. With a
single pass of a multi-bladed knife, they could produce multiple,
thin strips facilitating the quick dissection of grafts. Now,
since the advent of follicular unit transplantation, many
physicians will excise the strip with a single scalpel blade in
order to minimize the transaction of the follicular units. Most
follicular unit proponents feel that the transaction rate with a
multi- bladed knife is unacceptably high and could lead to reduced
growth of the transplanted hair.
In regards to the recipient area, during the early days of hair
transplantation, the 4 mm plug removed from the back of the scalp
was then simply implanted intact into the balding area in the
front of the scalp. This certainly gave volume to the thinning
hair but at the unacceptable price of extreme “plugginess” as
the remainder of the preexisting hair eventually disappeared.
Grafts were gradually down-sized to quartered 4 mm plugs and then
to minigrafts. Minigrafts are small plugs of hair containing 3 to
10 hairs each. They are produced by cutting the excised strip or
strips down to smaller sizes without magnification and without
regard to follicular units. This certainly reduces the harshness
of the “pudginess”, but by no means does it remove the problem
entirely. Instead of fewer, big plugs, there are numerous small
plugs. Micrografts were developed to hide this “plugginess” in
the hairline. Micrografts consist of 1 to 2 hairs dissected
without magnification and without regard to the follicular units.
These are a tremendous aid in helping to disguise the
artificiality of minigraft hairlines. |

Figure 4-4. Hair transplants are now performed by excising a
strip from the donor area, suturing the open area shut,
dissecting the strip into small grafts, and then transferring
them into small holes in the recipient area
|
| Follicular unit transplantation was
the next major milestone in hair transplantation. A follicular
unit is the natural unit hair grows in on the scalp. If the scalp
is shaved and magnified, the follicular units are evident as the 1
to 4 hair groupings exiting the scalp from single points. Each
individual follicular unit has a single root system. Follicular
unit transplantation is defined as the dissection underneath a
microscope of the individual follicular units followed by the
implantation of these single units into the balding area. Emphasis
is placed on not disturbing the root systems while dissecting the
1 to 4 hair grafts. A microscope is required for the adequate
visualization necessary to avoid transection of the follicular
unit root system. Since these 1 to 4 hair grafts are transferred
individually, there should be no “plugginess”. |

follicular units as bundles of 1 to 4 hairs.

The recipient site in the front or
top of the scalp must be prepared to accept the various forms of
grafts. The recipient site for the 4 mm plugs was simply a
similar-sized hole created with a punch. A punch is a small,
circular, cookie-cutter type knife that creates tiny, circular
holes in the skin. The recipient sites for minigrafts are made
with either scalpel blade incisions or small 1.5 to 2.0 mm
punches. Lasers have been utilized to create recipient sites for
minigrafts to no great advantage, but certainly at greater costs.
The recipient sites for follicular units are made by inserting
small needles into the scalp to create tiny holes.
The implanting of the grafts is considered the most technically
difficult portion of the procedure. As the grafts have become
smaller, the skill required to gently insert them with a fine pair
of forceps (tweezer-like instruments) has greatly increased. These
grafts must be grasped and inserted without traumatizing the
tissue, or poor growth is risked. This gentleness combined with
the close-spacing of the grafts makes a planter with good hands,
patience, and a sense of perfectionism, critical.
But does it hurt? The skin of the donor and recipient areas is
anesthetized with local numbing shots. Most surgeons will either
have their patients take pills to help them relax, such as Valium
or Xanax, or inject medicines intravenously to put them to sleep
before beginning the numbing shots. Although the intravenous
medicines sound appealing since the patient is asleep, the patient
and the surgeon must assume an increased level of risk. It is
possible for the patient to stop breathing for himself, and
monitoring equipment is required to check the patient’s status.
The risk of severe complications seems to be quite small, but from
a personal standpoint, that risk is not justified in my patients.
In no way am I suggesting that the use of I.V. medicines is
inappropriate. It is, simply, my experience that a patient who has
taken something orally to help him relax and who is treated with
gentleness and care does just as well, without the increased risk.
Various agents can be applied to the skin prior to the injections
to reduce the sensation of the needle stick. Injection techniques
such as tumescent anesthesia and nerve blocks further facilitate
patient comfort. Tumescent anesthesia involves the injection of
dilute anesthetics into the deeper, fatty tissue first. The fatty
tissue is far less sensitive to injection pain than the skin.
After it has been numbed, the skin injections are much less
tender. Nerve blocks involve the injection of anesthetic around
the bases of the nerves that supply the front of the scalp. These
are located right above each eyebrow. Once the bases of these
nerves are numbed, work in the central-frontal scalp is painless.
The primary reason injections anywhere on the body hurt is due to
the anesthetic being pushed into the skin too rapidly because
either the person performing the injection is impatient or
uncompassionate.
But, again, does it hurt? My answer is that if the procedure is
performed by an experienced, gentle, and caring surgeon, it will
hurt very little. After almost every procedure, I hear the same
thing, “If I would have known how easy this was, I would have
done it a long time ago”. On the other hand, if the surgeon
lacks these qualities, (whether done under I.V. sedation or not)
yes, it can hurt.
Very few hair transplants are performed by the physician alone.
With the advent of minigrafts, and then, especially, follicular
units, the amount of work required to prepare and implant the
grafts has increased logarithmically. Surgeons working alone would
only be able to perform small follicular unit transplantation
sessions. Most surgeons plan the procedure, perform the excision
and repair, and then oversee a team of technicians who dissect the
grafts and then implant them. In my office, a typical follicular
unit transplantation session will take six to ten hours and
require four technicians, two dissecting and two planting. During
the majority of the procedure, the patient relaxes in a reclined
position. He may pass the time by watching television or movies,
listening to music, chatting with the staff, or simply napping.
After the transplant is completed, bandaging of the head is
usually unnecessary. On occasion, if a patient is oozing a little
from the donor area, a bandage will be applied like a headband for
several hours. Patients leave wearing a baseball cap to hide what
has been done. Sutures or staples are removed in about ten days
from the donor area. There are no sutures in the recipient area.
The transplanted hair shaft typically falls out during the first
month after surgery. The root system is still present just as if
the hair had been plucked. The new hair starts to grow in three to
five months. This transplanted hair is now permanent hair not
susceptible to the progressive nature of male pattern baldness.
This hair may thin out when the patient reaches seventy to eighty
years of age, but this is a general thinning known as senile
alopecia which causes hair over the entire scalp to begin to
disappear. Otherwise, the new hair is permanent. The transplanted
hair occasionally grows in a little kinky and coarse during the
first year, but it will ultimately appear just like the hair in
the donor area. It will grow and need to be cut probably more
frequently then any surrounding miniaturized preexisting hair. It
can be colored and styled any way the patient likes. If another
transplant is desired, usually I will ask my patients to wait a
minimum of six months so that I will know where the new growth is
and I can transplant between the previous grafts. |
