Low Level Laser Therapy: Taking a Deeper Look
The
Principles of Low Level Laser Therapy or
photo-biotherapy is as old as sunlight itself.
Harnessing and refining the therapy with low
reactive lasers in hair clinic laser light hair
therapy program is relatively new. Low level
lasers are "soft" lasers, often referred to as
"cold" laser, and do not have the
thermal-component we normally associate with
other types of lasers.. Low Level Laser Therapy
(LLLT) is based on the scientific principal of
photo biotherapy.
Photo biotherapy occurs when laser light is
absorbed by the cells, which stimulates cell
metabolism that enables damaged cells to repair
themselves. Photo-biochemical changes in cells
can only be achieved with the correct amount of
light energy, delivered at the appropriate
wavelength. In his research studies, Dr. David
G. Williams has called low level laser therapy,
or LLLT, a miraculous healing tool.
Principles of Light Energy
Normal white light produces a thermal effect in
the skin. This is due to its relatively high
energy output, with a large share of its light
in the infrared spectrum being absorbed by the
water in the outer cell structures. Laser light
of a specific wavelength, penetrates deep into
the layers of skin and is absorbed, provoking a
photo-biochemical chain reaction.
A
Laser Light Hair Therapy device has multiple
diode lasers mounted in a half sphere, which
rotate around the entire head, delivering laser
energy to the tissues of the scalp. Laser energy
(Photons), penetrate deep into these issues and
are absorbed by deeper cell structures,
resulting in a photo-biochemical chain of
cellular and sub-cellular events. Laser Light
Hair Therapy has been clinically proven in
European studies to stimulate these cellular and
sub-cellular events, leading to a dramatic
increase in micro-circulation of blood supplies,
cessation of hair loss and stimulation of hair
regrowth.
Various light sources including lasers have been
used in attempts to stimulate hair growth and
stop the progression of hair loss since the
1950's.
In
1984 Dr. Trelles showed in one study that
patients with alopecia areata who were treated
with HeNe Laser 632.8 nm showed a good response.
Dr. Trelles reported that most of the patients
with alopecia areata responded well after only 6
to 8 treatments administered twice a week for
four weeks. The HeNe laser was placed 30
centimeters from the alopecia area with dosages
ranging from 3-4 joule per sq. cm. No fibers or
lenses were used. In the same study, microscopic
evaluation of the hair shaft structure on the
alopecia areata irradiated areas showed a clear
modulla rich in Keratin after treatment. Daily
treatments appeared to prevent regrowth, causing
irritation with a probable increase in hair
loss.
At
the Fourth Annual Meeting of the Japan Laser
Therapy Association in 1992, success was
reported with an increase in both hair growth
and the density of the hair follicle in the
laser treated areas of both male and female
stress alopecia and alopecia areata patients,
with only one failure out of 40 cases reported
in two papers.
Two
clinical double blind controlled studies have
been completed on Laser Light Hair Therapy:
-
Cessation of hair loss, increased regrowth
of hair with improved hair quality.
-
Increased circulation in scalp blood flow.
Hair Loss (Study #1)
A
double blind comparative study of laser
treatment with placebo laser (LED)5 for
treatment of Hereditary Androgenetic Alpecia in
young males. Abstract: A double blind placebo
controlled study was carried out to evaluate the
effect of laser therapy by comparing Laser Light
hair Therapy (inGaAl, 670 nm) and a placebo
laser (LED). The duration of hair loss and
baldness, according to the Hamilton
Classification, were recorded. A skin biopsy for
histological examination was taken before and
after treatment. In addition a photograph was
taken of the patient at the same time. Hair
shaft thickness was measured with hair stretched
equipment where the hairs can be stretched on a
graded scale from 0-10, normal value of hair
shaft being 0.5.
There results were confirmed by histological
examination. All patients with the exception of
one in the laser-treated group showed a complete
cessation of hair loss. All patients except 3,
showed a clear regrowth of hair with a reduction
of as least one category in the Hamiliton
classification. Pre-treatment typically showed
the dermis with large, relatively normal amounts
of follicles. Most of them were in the telogen
phase and did not show any real hair. Some of
the follicles were widened with keratin taps at
the follicle opening. Post-treatment showed the
dermis with almost the same amount of hair
follicles as pre-treatment, although a number of
new follicles could be seen with clearly
noticeable hair growth. 50% of the follicles
were now in the anagen phase. A clearly visible
regrowth of hair was found in post-treatment
sample comparison. When comparing the
histological findings, transformation into more
anagenic hair follicles could be observed in 83%
of the patients on laser treatment, but in none
of the placebo patients.
Out
of 18 patients, 14 showed an increase in hair
thickness, and all 18 patients showed
improvement in general hair shaft quality. When
measured with the hair stretcher, the results
showed no improvement in the placebo group or
any adverse effects of the treatment. The
present double-blind study definitely showed
that regrowth of new hair can be achieved in
most middle-aged and younger males, with typical
male pattern baldness, when the scalp is
irradiated with Laser Light Hair Therapy for 30
minutes twice weekly for 5 weeks, with follow-up
maintenance treatments.
Is Laser Hair Therapy Safe?
Yes! Low Level Laser Hair Therapy is safe and is
classified as a Class IIIA cosmetic laser. The
energy produced by the photons does not have the
thermal component to cause thermal injuries to
patients or administering staff. Laser light
energy does not change or alter molecular
structures.
Low Level Laser has been used for numerous
conditions in Europe for over thirty years and
has been the subject of over 2,500 scientific
papers, published worldwide. There are no
reported side effects to the treatment which is
painless, and non-toxic.
As administered, New Look Institute’s low level
laser hair therapy combines the most efficient
treatment methods into one treatment system
offering you the most effective treatment for
improving hair volume and hair shaft quality
available. A unique approach uniting the most
efficient treatment methods into one system
offer the most efficient modality to improve
hair shaft quality and hair volume. At New Look
Institute, our approach is to combine a
traditional cosmetic treatment with a Trichology
concept that is recognized world-wide, including
hair loss control and rejuvenation therapy with
approved growth activators.
Ask Yourself…
“What would having more hair volume do for you?
What if my hair had more density and was
thicker, fuller, and healthier looking? What
would that do for me? Would I have more
confidence, look younger, and feel better about
myself? Would it help improve my career
opportunities?
We invite you to call today for your FREE hair
and scalp analysis using our Microscopic Hair
and Scalp Analysis system.
At New Look Institute knows there is no “magic
bullet” or cookie cutter solution to hair loss.
The cause may be genetic, nutritional, hormonal,
chemical, or auto-immune. We consider the
“whole” individual, including diet and stress in
our approach to helping you solve your hair loss
problem and helping you regain stronger thicker
healthier looking hair.
