Hair
transplantation is a permanent solution to hair loss. Just
as there is hair genetically programmed to fall out there
is also hair genetically programmed to stay forever. The
area in a horseshoe shape, (click
here for diagram) from ear to ear, is the least amount
of hair that is guaranteed not to fall out. This hair can
be easily removed in a strip without any obvious signs and
placed in the areas where you are balding. The strip is
closed with a suture, which is removed after 10 –
14 days. The transplanted hair will grow for the rest of
your life.
Hair
transplants should look perfectly natural, single hairs
are used to recreate a natural hairline while follicular
units, naturally occurring groups of hair from 1 to 4 haired
are used to give density behind the hairline.
Stereoscopic
microscopes enable us to identify and dissect follicular
groups.
Hair
transplantation is an ongoing solution to an ongoing problem.
A thinning area may need only one transplant while a bald
area may need two treatments to achieve density. As you
lose more hair it can be replaced if you require.
As
a general rule you can lose 50% of your hair density before
you begin to notice any hair loss, it is therefore reasonable
to assume that by maintaining 50% of your original hair
density to achieve the look of a person who is not losing
their hair. However this does depend on the amount of hair
you lose. If you lose lots of hair i.e. Norwood classification
5-7, you can only expect to achieve a thinning look.
This
is because everyone has a limited amount of donor hair that
we can move around; for example, if you are a only ever
going to be a Norwood grade 3 hair loss, you have this much
hair to transplant into the bald area; (diagram) Whereas
if you are a grade 7 Norwood you have more bald scalp but
similar amount of donor hair. (diagram) When we are able
to clone hair you will have an unlimited amount of donor
hair to fill in the bald areas. However this technology
is currently still unavailable.
How
is density achieved?
Most
Doctor will transplant 25 follicular units (fu’s)
per square centimetre, some hair clinics can achieve up
to 40 fu’s per square centimetre but this would only
be on a bald area. Therefore two operations of 25 fu’s
per square centimetre could give you the density you require.
Follicular
units (fu’s)
Follicular
units are naturally occurring groups of hair. They occur
in groups of 1 to 4 and in people with very dense hair;
groups of 5 or 6 hairs had been noted. They are bound together
by collagen and have one sebaceous gland. They cannot be
seen with the naked eye; that’s why we use stereoscopic
microscopes to identify them and dissect them accurately.
This means that the fu’s can be transplanted intact
giving every hair the best possible chance to survive and
grow.
Micro
and mini grafts
Anything
bigger than an fu but not a plug graft is a mini or a micro
graft. This may contain more than one fu, this doesn’t
necessarily mean that they’re bulky or unnatural but
they should be used with careful planning and never on the
hairline. As they are bigger than fu’s you should
expect less per square centimetre.
Plug
Grafts
Plug
grafts are the things that give hair transplantation a bad
name. Up to about 10 years ago they were “state of
the art” in this field.
A
circular plug of 3-4mm diameter was taken from the back
of the head in the area where your hair will always grow,
a similar sized plug in the bald area is then removed and
the hair bearing plug is then placed in the bald area, angled
appropriately and left to grow.
This
procedure left a circular scar on the back of the head.
Dr’s were always careful to leave enough hair in between,
above and below the scar to ensure it remained concealed,
this meant that it limited the amount of donor hair available
and left the patient with lots of circular scars.
Plugs
were great at giving density to a hair transplant but unless
you had white hair and white skin they were obvious on the
hairline. They worked best when placed behind the hairline
but if you then went on to lose your hair around the plug
grafts, it would expose the plugs, as they were never meant
to be a hairline they look unnatural.
What
to do if you’re unhappy with your transplant.
If
you have any type of surgery that you are unhappy with,
the good news is that you don’t have to live with
it. Grafts can be disguised or removed either individually
or in a row if necessary, i.e. if they are too low on the
hairline and therefore cannot be disguised or in the case
of plug grafts if they are just too dense and at the wrong
angle. Aesthetically acceptable grafts/follicular units
can then be placed around the larger grafts or unacceptable
work making the hair transplant look natural /acceptable.
Unsightly donor scars can also be removed.
This
work requires a high degree of skill, knowledge of surgery,
dermatology and the principals of hair transplantation.
The
great success of this type of surgery means that you can
stop having to cover up those unsightly grafts.
