Tampa, Florida, Oct. 5, 2003 - In a clinical
study published in the International Journal of Cosmetic
Surgery and Aesthetic Dermatology, Volume 5, Number
2, 2003, the efficacy of Low Level Laser Therapy with
the HairMax LaserComb was studied to determine if anecdotal
evidence was supported by clinical data.
The authors wished to test the efficacy of Low Level
Laser Therapy (LLLT) using a HairMax LaserComb for the
stimulation of hair growth and also to determine what
effect LLLT with this device had on the tensile strength
of hair.
Male and female patients with Androgentic Alopecia,
aged 28 to 76, were each given a LaserComb to use at
home for six full months. Hair counts were done in the
areas of greatest hair loss in the temporal and vertex
regions at the beginning of the study and again after
six months. Changes in the tensile strength of the hair
were also recorded during this study.
Hair counts increased in the temporal area an average
of 55.2% for women, 74.1% in men and 69.1% for all patients.
In the vertex area, the corresponding percentages were
64.9% for women, 120.1% for men and 111.9% for all patients.
The combined average hair count increase for all men
and women in the temporal and vertex areas was 93.5%.
Additionally, the hair tensile strength was increased
78.9% when all temporal and vertex patients were considered.
28
males aged 28 to 72 and 7 females aged 46 to
76 were given a HairMax LaserComb to use at home for
six full months and instructed to comb his/her entire
scalp hair slowly (advancing one-quarter of an inch
per second) for five to ten minutes every other day.
The treatment was to be carried out when the hair and
scalp were clean and the hair was dry. A hair count
in the greatest area of alopecia and a determination
of the tensile strength of the hair was carried out
before treatment was started and again, after six months
of treatment.
A clear acrylic mold of each patient’s
head was created with the front of the mold positioned
at the hairline, and a one centimeter square removed
from the mold in the area of greatest alopecia in either
the temporal or vertex region. For the hair count, the
hairs within the one square centimeter space were pulled
through the opening, and then counted using a surgical
skin hook and a lens with five times magnification.
Hair counts were carried out by both authors to confirm
the accuracy of the data.
The mechanism or mechanisms of action of LLLT are
unknown with regard to the stimulation of hair growth
or how the hair tensile strength is increased so greatly.
From wound healing studies, it is know that
LLLT causes an increase in the microcirculation of tissue,
and a reduction in inflammation. The amount of cellular
energy in the form of adenosine triphosphatase (ATP)
is also increased following LLLT. Perhaps one or more
of these beneficial effects are responsible for the
results we were able to achieve. The authors hypothesized
that the early temporary hair shedding experienced by
some patients was most likely related to an accelerated
hair cycle in general. Obviously, more research is required
if we are to understand the scientific findings noted
in this paper with greater clarity.
