Some scam web sites have numerous photographs to demonstrate just
how much hair regrowth their product gives. The camera never lies
First, several sites have before and after pictures of individuals
who are clearly undergoing hair transplantation, and not very good
hair transplants at that. The hair plugs from transplanting are
clearly visible and the pictures simply record the growth of hair
after the surgical procedure. It is possible the pictures were actually
scanned from a dermatologist hair transplant book or were obtained
from a transplant clinic. Some clinics operating in poorer parts
of Europe, Asia and Africa are less than scrupulous in protecting
patient confidentiality and who obtains their photographic records.
Second, changes in hair styling and or use of cosmetic hair thickeners
will change the look of the hair density. One or two before and
after photographs simply show someone with a short hair cut and
then a few weeks later with longer hair to cover the bald areas.
Third, The angle of the head at which the photo is taken is important.
Looking along the top of the head rather than down on it will show
an apparently dense crop of hair in someone with a diffuse hair
loss. Looking down on the top of the head of the same person may
show the distribution of hair to be quite sparse.
Fourth, there are some technical aspects of taking portrait photographs
that alter the look of a person and their hair density. a) Using
zoom lenses, photos can be taken of the same person to fill the
camera frame but with the photographer at different distances from
the subject. The further away the photographer the less reflected
light on the skin between hair shows up in the picture. b) The photographer
may use a flash. This will provide an intense light that bounces
off the skin from in between hair making the individual look very
bald. c) Using a polarized filter on the camera reduces this reflected
light and allows any hair present to become more obvious in the
photograph. d) In the same way, the color of clothing and background
is also important in determining the amount of light reflected onto
the head and into the camera. Some before and after photographs
are clearly taken within a few minutes of each other, the model
doesn't even bother to change his shirt!
Of course in this day and age of computers it is very easy to manipulate
photogrpahs with the appropriate software. There are some very good
examples of computer manipulated images on snake oil selling web
sites. There are also some very obvious fake phots on the more amature
