Presently there are three different techniques to take the hair
from the back and sides of the head and transplant in the concerned area of
thinning or balding. Following are the techniques.
1- Auto Cloning
2- Follicular Unit Extraction FUE
3- Long Hair Technique
Auto Cloning
Donor area is marked, a vertical line is drawn in front of the
ear, behind this vertical line, in the parietal and occipital area, 2cm of
healthy hair are left in the upper and the lower margins. The area within the
above mentioned margins is considered the Donor area for Auto Cloning.
Special surgical Forceps are used for plucking the hair. An
average 30 hair are firmly held in the forcep close to the scalp and these
firmly held hair are plucked out with gentle wrist jerk. Most of the hair come
out with this technique have intact inner and outer root sheaths. The pulled
hair are delicate and are placed in chilled saline and treated with A cell
growth factor for better survival.
Alternative Techniques of Performing Auto
Cloning
Platelet Enriched Plasma
The plucking technique is same. 20-30 cc of client blood is drawn
and centrifuged, it separates the blood into 3 layers, Red blood cells, white
blood cells and platelets enriched plasma. Plucked follicles are treated with
persons own activated platelets. These activated platelets have growth factors
as well as few inhibitory factors. Due to presence of inhibitory factors in the
activated platelets the survival of plucked hair treated with activated
platelets alone are inconsistent and the survival varies from average to good.
A Cell is driven from pork bladder cells. If the client wants to choose the
Auto cloning technique without A Cell, only in this situation Activated
platelets should be used to treat the plucked hair.
Stem Cells
Approximately 10 CC of fat is taken from the abdomen by
liposuction. The fat is centrifuged, then treated with collagenase and
incubated. The process allows separation of stem cells, each CC of fat provide
an average 500,000 to one million stem cell. The plucked hairs are treated with
these stem cells. Stem cell treatment of plucked hair is under study at the
moment.
Advantages of Auto Cloning
1-The hairs which are plucked with this technique grows back in
the donor area. In Long Hair Technique and FUE Techniques, it's the
redistribution of hair and total number of hair after transplant stays the
same. In Auto Cloning the total number of hair increase after the transplant as
the plucked hair 100% grows back in the Donor area and 50-70% of plucked hair
grows in the transplanted area.
2-Clients with limited donor hair can benefit from this technique.
3-Donor area scars of the previous hair transplants can be treated
with this technique.
4-If the person does not want to use FDA approved medication to
help reduce or stop the hair loss, Auto Cloning can be repeated without
depleting the donor area.
5-There is no temporary numbness of donor area.
Disadvantage of auto cloning
1-Good density in one surgery could not be attained with Auto
Cloning, as the survival of the plucked transplanted hair is 50-70%.
2- Auto Cloning works on 80% of the clients. The plucked hair in
the remaining 20% of the clients come out without outer root sheath, if planted
they do not survive.
Follicular unit extraction ( FUE )
Donor area is marked, a vertical line is drawn in front of the
ear, behind this vertical line, in the parietal and occipital area, 2cm
of healthy hair are left in the upper and the lower margins . The area within
the above mentioned margins is considered the Donor area for FUE.
A shaved donor area is needed for Follicular unit extractions. The
donor area can be partially or completely shaved. If the Donor area is
completely shaved, 2000-3000 follicular units can be extracted in one day
surgery. If donor area is partially shaved in a way that top hair cover the
shaved areas, in this situation only 1000-1500 follicular units can be
extracted. Special micro punches are used to punch out the follicular units.
Motorized micro punches are faster.
Different approaches for follicular extraction
1- Manual micro punches technique
2- Motorized micro punches technique
3- Motorized Suction punches technique
4- Robotic punch technique
For extraction few Doctors prefer using manual punches and
few prefer motorized punches . There is also a suction based extraction
machine, hair technician mostly operate this machine to save time for the hair
transplant surgeon. There is robotic machine available for follicular unit
extraction as well.
The goal in using any of the above mentioned technique is minimum
damage during extraction.
Advantages of FUE
1-Once the donor area heals , there is no noticeable scarring in
the donor area .
2-Client has the flexibility to wear the hair extremely short or
even shave off the hair without the fear of any visible scaring in the donor
area.
3-If the donor area is very tight, FUE technique can be used.
4-FUE could be combined with long hair technique to maximize the
total numbers of follicular units transplanted in one surgery. In long hair
Technique, there is a maximum safe limit of taking out follicular units, which
varies individually from an average 2000 to 6000 follicular units. For example
5000 follicular units are obtained by long hair technique; still average 500 to
1000 follicular units can be extracted by FUE technique without adding any
tension to the donor area.
5- FUE can be repeated after one month, long hair technique can
not be repeated before 6 month.
Disadvantages of FUE
1-The micro punch is moved down over the follicular unit to cut
free the tissue around the follicular unit, so the follicular unit free to be
extracted out with fine forceps. Due to blind cutting to make the
follicular units free to be extracted, the punch can damage an average 5% of
the follicular units.
2-The punching and extracting out process in FUE can traumatize
the follicular units it can lead to decrease survival.
3-There is a limitation of an average 2000 to 3000 follicular
units extraction in one surgery.
4-If the head is shaved to extract maximum follicular units,
extraction sites are visible for on an average 10 days.
5-In transplanted area surgery is noticeable for an average 10-15
days.
6-There is Temporary numbness feeling in the Donor and
transplanted area.
Long Hair Technique
A horizontal line is marked In the middle of parietal and
occipital area, leaving equal amount of hair above and below the line.
Depending on the individual flexibility and laxity of the Scalp, this marked
line is stretched on an average from 1cm to 2.5 cm. An incision of an average
0.5 mm deep in the direction of hair is made at the upper and lower borders of
the marked donor area. Skin hooks are used to open up the upper and lower
incision. The incision margins are stretched by skin hooks, the follicular
units in the incised area get separated. As this technique offers direct
visualization, there is no damage to the hair. The extracted hairs are intact
and non traumatized. Once the Donor hair strip is out, there is an average 1-2
cm gap depending on the width of the extracted strip and upper and lower skin
margins. In the upper skin margin, an average 1 mm wide and 3/4 mm deep tissue
is shaved (Trichophytic Technique). In the tissue gap, A Cell growth factor
sheath is laid for better healing. The upper and lower edges are fine
stitched together. Hair grows out in the scar line because of Trichophytic
technique, most of the time scar line becomes undetectable due to trichophytic
closure.
The follicular units are separated under the microscopes. The
average hair damage in strip removal and in the preparation of follicular units
under the microscope is 0 to 0.4 % of the total number of hair.
Alternative Approaches For Long Hair Technique
Most of the doctors Trim the marked donor area. Incision is made
up to the full follicular depth by single or multiple blades, A Cell is not
used. Full follicular depth incision leads to higher hair damage. Use of
multiple blades further increases the risk of higher follicular damage.
Advantages of Long Hair Technique
1-There is damages of 0 - 0.4% in comparison with FUE damage of 5%
in follicular units preparation.
2-These follicular units are intact and non traumatized with
almost 100% survival.
3-An average 4000 follicular units can be performed in one
surgery. If the flexibility and density is good, an average of 6000 follicular
units can be performed in one surgery.
4-Long hair Technique could be combined with FUE or Auto Cloning
to increase the number of follicular units transplanted in one surgery. If the
donor area is very good and has good laxity and flexibility, combining long
hair technique and auto cloning can provide up to 10,000 follicular units to be
transplanted.
5-Higher follicular unit numbers and near100% survival help to
achieve client’s goals in one surgery.
6-The donor hair is not shaved or trimmed, stitches are covered by
one’s own hair.
7-The same length transplanted hair on the front keep the surgery
sites unnoticeable.
8-The long hair transplanted in the hairline give the preview of
the future hairline and outcome. Follicular units can be readjusted if needed
during the surgery depending on the initial look.
9-Trichophytic fine stitch closure and use of A Cell sheath, leads
to very fine scar and sometime unnoticeable scar. The area is covered by one’s
own hair.
Disadvantages of Long Hair Technique
1-If a person trim the hair extremely short like No 1 Machine or
shave off the hair, there are chances of noticeability of stitches mark or fine
scar in the donor area.
2-Temporary numbness feeling in the donor area.
3-Increase chances of shock hair loss in the transplanted area.
Hair lost due to shock grows back along the transplanted hair.
Planting The Follicular Units In Auto Cloning,
FUE And Long Hair Technique
Recipient Sites
In creating the Recipient sites, important consideration is given
to four things.
1- Size
2- Angle
3- Direction
4- Types
Size
Follicular units diameter is the main determining factor for the
recipient site size.
Recipient sites are made with custom cut micro blades in all three
techniques. These micro blades are custom cut according to the size of the
follicular units. For single hair follicular unit, the average size of the
micro blade depending on hair diameter is 0.6 to 0.7 mm. For two hair
follicular unit average size of the micro blade is 0.7-0.8 mm. For three to
four hair follicular units, the average size of the blade is 0.8-0.9 mm.
Needles and special blades also can be used for creating the sites.
Angle
Hair exit the scalp at different angle in different part of the
scalp. In the hairline area , hair exit the scalp at an average 20 degree , as
moving back toward the mid scalp angle gradually increases from 20 to 60 degree
, moving further back angle gradually start decreasing in the crown area . In
the occipital area, the hair exit the scalp at an average 20 degree. In the
parietal area the hair exit the scalp at an average 20 degree angle. In the
temple area the hair angle of exit is an average 10 degree.
Direction
In creating the recipient sites, important consideration is given
to the direction as well. Sites are made according to the natural direction in
the bald area. In the hairline ,near the frontal midpoint , hair are directed
forward , as moving from the frontal mid point toward the fronto temporal
angle , hair gradually start directing sideways . Moving back in the mid scalp,
the hair direction is same, but the angle change from 20 degree in hairline to
60 degree in the posterior part of the mid scalp. In the temple area, hair are
directed down and backward. In the parietal area and occipital areas, hair are
directed downward. In the crown or vertex area hair are in whorl pattern.
When creating sites in the thinning area, direction of the sites
and angle of exit from the scalp is matched to the existing hair.
Types
There are two types of sites
1- Perpendicular
2- Parallel
Perpendicular
With perpendicular site creation the width throughout the length
of the site stays same at any angle. When multiple hair follicular units are
transplanted in perpendicular sites, Hair are lined side by side, it creates
better density.
Parallel
With parallel site, the width of the site at skin level is an
average 50% more. When multiple hair follicular units are transplanted in
parallel sites, hair are lined behind each other, creating a less dense look in
comparison to perpendicular sites.
Advantage of perpendicular sites
1-In the hair line the average desired angle of hair exit from
skin is 20 degree. As the width of site throughout it length is same, it allows
to achieve desired angle.
2-The the superficial trauma to the skin on an average is 50% less
than the parallel sites.
3-As the width of site throughout it length is same, the
follicular units has equal pressure through out the length of the site, leads
to better healing.
4-In the area behind the hair line, two and three hair follicular
units is used, hair is lined side by side, and it creates a look of better
density.
Parallel sites
1-The width of the site throughout the entire length is same only
if the sites are made at 90 degree angle, as the angle decrease the width of
the site at skin level increases. In the hair line and temple area where the
desired angle is 20 degree and 10 degree respectively, the width of the site at
skin level is an average 50% more, it leads to increase superficial trauma ,
delay in healing and inability to maintain the desired angle .
2-As the width of the site is more at skin level, the pressure on
the follicular units decreases toward the surface. The uneven pressure on the
follicular units can lead to difficulties in placing.
3-As the width is more at skin level, especially in hair line and
temple area where the desired angle is 20 degree and 10 degree respectively,
the follicular unit has more room to move so the desired angle cannot be
achieved.
4-Behind the hair line where two and three hair follicular units
are used, the hair are lined behind each other, create a less dense look in
comparison to perpendicular sites.
Auto Cloning
The plucked hair are very delicate, after plucking hair are
trimmed and dipped in A Cell Growth factor solution. Special precautions are
taken during planting as the follicles do not have much supportive tissue
around them. The survival of these follicular units are between 50 to 70 %. The
transplanted area is noticeable for 10- 15 days.
FUE
The extracted follicular units are already trimmed, before
planting the follicular units, they are treated with A Cell Growth factor
solution. The survival of follicular units are 90 - 100 %.
The transplanted area is noticeable for 10 -15 days.
Long Hair Technique
The follicular units prepared under microscopes are healthy and
strong . Survival of these follicular units are 100%. Use of A Cell is
optional. These follicular units are untrimmed, when planted, keep the surgery
sites unnoticeable and provide the preview of final outcome.
Alternate Approach To Long Hair Technique
The follicular units prepared under microscopes are healthy and
strong. Survival of these follicular units are 100%. Use of A Cell is optional.
These follicular units are trimmed. The transplanted area is noticeable for
10-15 days.
HOW TO CHOOSE THE RIGHT SURGERY FOR YOURSELF
Auto Cloning
Auto Cloning technique provide the multiplication of hair. The
only technique where the total number of hair on the head increase after the
transplant.
If the donor area is limited, without further reducing the donor
area, hair can be transplanted
Newest option
Minimum post operative pain in the Donor area and no temporary
numbness in the donor area.
FUE
Reasons to Choose FUE
1- If the life style of the client is to wear the hair very short
like number 1 machine or keeping the hair shaved most of the time, FUE is
better choice of not having any visible scaring in the donor area.
2- If client does not want to have incision and stitches, FUE can
be chosen.
Long Hair Technique
Reasons to Choose the Long Hair Technique
1- Only technique which allows to go back to work next day without
any surgical sites notice ability.
2- Long hair technique offers more follicular units in one surgery
which results in major change in appearance.
3- Survival of transplanted hair is better than other techniques.
4- Long hair technique provides reasonably good density in one
procedure.
5- Hair damage during the surgery is minimum 0-0.4 % with long
hair technique.
6- With Long hair technique there is a
possibility of fine scar in the donor area which is covered by the hair. If the
lifestyle is to wear the hair half an inch or more in length most of the time,
long hair technique is the absolute best choice. Best Hair Loss Treatment | Female Hair Loss Treatment
