1) A Brief History
of Hair
Throughout history,
hair has been an
important symbol.
The significance of
hair as an indicator
of gender, and
social, religious
and professional
status has been as
great as that of
clothing, jewelry,
tattoos, weapons,
and even crowns.
The importance of
hair goes back at
least as far as the
Neolithic Age.
Several years ago, a
man’s body was found
frozen in a glacier
near the
Austrian-Italian
border. Because he
looked like modern
man, it was first
thought that he had
died only a few
years before. Upon
examination of his
clothing and
weapons,
archaeologists
concluded that he
had been frozen for
more than 5,000
years. It is likely
that this preserved
Neolithic man wore
his hair in the
fashionable cut and
style of that age.
His hair was neatly
cut to a length of
3.5 inches, and his
beard was trimmed.
In Ancient Egypt,
sons of the Pharaoh
wore their hair tied
in a distinctive bun
on the right side of
the head just behind
the ear. The Pharaoh
himself was never
seen without a wig.
Even today, male and
female English
judges wear
obviously artificial
horsehair wigs when
they preside in
court.
The oldest known
medical text is an
Egyptian papyrus
scroll. Its remedies
include an ointment
for restoring lost
hair, consisting of
equal parts
crocodile fat and
hippopotamus dung.
The physician who
wrote the text
recommended that one
rub this concoction
into the bald scalp.
The ancient Greek
physician,
Hippocrates,
recognized a
connection between
the sexual organs
and baldness. He may
have been the first
to record the
observation that
eunuchs (men
castrated before
puberty) did not
become bald.
Hippocrates' own
baldness stimulated
his interest in the
subject of hair
loss. His
prescription for
preventing hair loss
was the application
of a mixture of
cumin, pigeon
droppings,
horseradish, and
nettles to the
scalp. In fact, the
area of permanent
hair that encircles
the back and sides
of the head is
sometimes referred
to as the
Hippocratic wreath.
Dating back to
Biblical times, the
tale of Samson is
one of the familiar
examples of man's
concern over hair
loss. Samson had the
strength to destroy
the Philistines as
long as his hair
remained long and
uncut. As soon as
Delilah cut his
hair, he lost all of
his strength.
Early Christian
monks and priests
shaved the hair on
the crown of the
head to create a
tonsure. This highly
visible mark
proclaimed their vow
of chastity to the
world. It symbolized
their lack of
concern with worldly
vanities and riches;
it also expressed
their personal
dedication to God.
During the Middle
Ages, Christian
society saw an
emphasis of concern
with the spiritual
side of life and a
studied neglect of
physical functions.
The tonsure became
so extreme that,
upon taking orders,
a monk shaved his
head almost
completely bare, so
that only a narrow
fringe of hair
remained encircling
his head.
During the time of
King Louis XIV of
France, elaborate
wigs became
fashionable for the
aristocracy. Some of
these wigs
incorporated
paraphernalia such
as model ships and
cages with live
birds. The more
complex
constructions often
weighed 15-20
pounds. Known for
luxuriant hair in
his youth, King
Louis began this
practice and may
have adopted the
fashion to disguise
his balding as he
grew older.
Elaborate wigs
continued to be a
class status and
fashion symbol until
the middle of the
eighteenth century.
Hair has also been
an important symbol
of rank and religion
in Asia. Buddhist
monks shaved their
heads completely.
Japanese Samurai
warriors shaved the
front and top of the
head and drew the
long back and side
hair into a complex
topknot. Even modern
day Sumo wrestlers
wear their hair in a
distinctive knot at
the back although
they do not shave
the front and top.
The ubiquitous queue
or pigtail of
Chinese men, a long
single braid worn
down the back, was a
symbol of their
bondage to a lord,
landowner, or to the
Emperor.
Most urban Chinese
men cut off their
queues after the
revolution in 1920,
but the custom
persisted in many
rural areas. During
the revolution, any
man found wearing a
queue was publicly
humiliated; his hair
was cut off and
burned.
Today, hair
continues to be an
important part of
self-expression, and
can function as a
symbol of attitude,
culture, and
religion. Hair, or
the lack of it, is
of great
significance to rock
singers, punks,
Rastafarians, Hare
Krishnas, Orthodox
Jews, Sikhs, Sufis,
Buddhists and
Hindus. Hair is
important to our
self-image and
self-identity, and
for both men and
women, it is a
universal symbol of
youth.

2)
Hair and Its
Functions
The condition of
one’s hair is an
important indicator
of age and the
body’s general state
of health. Other
similar indicators,
such as skin
condition, muscular
coordination,
brightness of the
eye and alertness of
manner, are often
more subtle or may
be masked by
clothing. Hair,
however, is usually
in plain sight.
There are
associations and
social reactions
that may result if
one’s hair is gray
or a man is bald. It
has been thought
that such reactions
were based on primal
judgments, such as
whether the person
is fit for warfare,
reproduction, and
for active labor. A
full, glossy head of
hair is a clear
signal that one is
youthful, vigorous,
and therefore,
desirable.
Hair is composed of
a complex protein
called keratin.
Human body has three
basic compounds: ,
proteins, fats, and
carbohydrates; the
synthesis of protein
requires the
greatest investment
of energy. When a
person becomes ill
or malnourished,
his/her hair stops
growing. When
illness or
malnutrition is
severe or prolonged,
the hair may fall
out (the medical
term for this is
telogen effluvium).

Telogen Effluvium
The resumption of
hair growth is a
sign that recovery
has begun. Science
continues to explore
why hair grows or
fails to grow, and
why it falls out in
some people, but not
in others. Mammals
share several
characteristics.
Most mammals bear
live offspring (as
opposed to laying
eggs) and nurture
their young with
milk made in special
glands on the
female’s body.
Mammals are
warm-blooded, that
is, they maintain
constant body
temperature
independent of the
outside temperature.
Hair is a feature
shared by all
mammals; and like
many mammals, man’s
skin is covered with
hair. Human skin has
more hair follicles
per unit of surface
area than the skin
of most other
primates; which this
is surprising, since
as most primates
appear to be so much
hairier than humans.
This impression is
caused by the
greater length and
coarseness of the
individual hair
shafts in primates
such as monkeys and
apes. In contrast,
the majority of
human body hair
consists of a very
fine, almost
invisible, type of
hair called vellus
hair. Human hair is
classified into two
main types:
-
Fine, Vellus
hair; and
-
The coarser,
more visible
Terminal hair.
Except for the palms
of the hands and the
soles of the feet,
most of the human
body’s areas of
seemingly bare skin
are actually covered
with very fine
vellus hairs that
may be almost
invisible except to
under very close or
microscopic
inspection. There
are several distinct
subtypes of terminal
hair. For example,
eyelash hairs,
called cilia, are
different from head
and body hair.
Pubic (groin) and
axillary (armpit)
hairs are also
different from
terminal hairs on
the head and are
associated with
different types of
glands in the skin.
Even scalp hairs
have several
different
sub-groupings. For
example, there is a
fringe of very fine
hair surrounding the
circumference of the
head. This hair
gives a transitional
gradation of
thickness from the
bare skin appearance
of the vellus hair
to the dense, thick
hair of the crown.
Similarly, the hair
above the ears or at
the base of the neck
is not as coarse as
that of the crown.
The reasons we have
hair and the
functions of its
growth patterns are
not completely
understood. Our
pre-historic
ancestors were much
hairier than we are
today; the reason
for the decreased
hairiness of modern
man is unknown,
although it is
reasonable to assume
that it parallel the
use of clothing for
warmth and
protection. Hair
serves as insulation
from the cold;
however, this does
not explain why
different human
groups have distinct
patterns of hair
growth. Most people
of Asian descent
have very sparse
body and facial
hair, but some of
these peoples such
as the Inuit,
Tibetans and Mongols
people, inhabit some
of the coldest
regions on earth.
Hair has the
additional function
of extending the
sensory capability
of the skin beyond
its surface.
Although human hair
lacks the wealth of
sensory nerve fibers
found at the root of
whiskers of some
animals, each hair
has a nerve fiber
going to the bulb of
the hair follicle.
Mechanical
displacement of each
hair causes a
sensation, an
awareness of
movement. For
example, when an ant
or fly walks on
one’s arm, one feels
the displacement of
hairs caused by the
insect.
Hair plays a role in
the defense
mechanisms of most
fur-bearing animals
as well. When an
animal confronts a
potential enemy, its
fur bristles,
standing on end to
make the animal
appear to be larger
and more
threatening. In
dogs, this response
is most visible in
the neck area where
the neck hairs,
called hackles,
rise. In cats, the
most visible
response may be in
the tail. An extreme
example of the use
of hair for
self-defense occurs
in porcupines: their
quills, which are
modified hairs,
stand out from the
body when the animal
feels threatened.
Porcupines have
converted a reflex,
that in most animals
is purely defensive,
into a formidable
weapon. In modern
man, with relatively
sparse body hair,
only vestigial
traces of these
reactions remain. A
separate, tiny
muscle connects the
lower portion of
each hair shaft with
the underside of the
skin. When you are
frightened, cold or
angry, these small
muscles, called
erector pili
muscles, contract,
causing your hair to
stand on end.
Each hair shaft also
contains a small
gland called the
sebaceous gland,
located next to the
hair shaft.
Sebaceous glands
make a yellow, fatty
substance called
sebum that
lubricates the hair.
Each time the
erector pili muscle
contracts, the gland
is squeezed, and a
small amount of
lubricant is applied
to the surface of
the hair. Hair,
along with skin
pigmentation, is the
major natural
protection that we
have against the
sun’s harmful
ultra-violet rays.
Scalp hair also
plays an important
role in preventing
mechanical trauma to
the skull. Hair acts
as a "dry lubricant"
in areas that rub,
such as under the
arms and in the
groin, and serves to
disperse pheromones
(body secretions
that are involved in
sexual attraction).

Hair is integral to
our body image and
can have a profound
influence on our
self-esteem and
self-confidence.
There is no other
part of the human
anatomy that can be
changed or
manipulated so
easily. Hair can be
groomed, styled,
waved, straightened,
dyed, braided, or
cut, and, unlike
tattoos or body
piercing, changes
made to our hair can
be completely
reversed. Hair
serves as a means of
self-expression, and
the loss of this
form of
self-expression in
people who are going
bald may account, at
least in part, for
the despair that
they may experience.
For all of its
simple appearance,
hair is a complex
and valuable organ.
Although we usually
think of hair only
in terms of the
visible portion of
the hair shafts,
each hair, along
with its muscle and
sebaceous gland,
must be working
properly to maintain
a healthy head of
hair.
Anatomically, hair
is a part of the
skin. As hair is
physically distinct
however, it is among
the structures known
as skin appendages.
Other skin
appendages include
sweat glands,
fingernails and
toenails. Skin is
composed of three
main layers. The
outer layer of skin
is the epidermis.
This layer is less
than a millimeter in
thickness and is
composed of dead
cells that are in a
constant state of
sloughing and
replacement. As dead
cells are lost, new
ones from the
growing layer below
replace them.
Beneath the
epidermis is the
dermis, a tough
layer of connective
tissue that is about
2 to 3 mm thick on
the scalp. This
layer gives the skin
its strength, and
contains both
sebaceous glands and
sweat glands.
Beneath the dermis
is a layer of
subcutaneous fat and
connective tissue.

Layers of Skin
The larger sensory
nerve branches and
the blood vessels
that nourish the
skin run deep into
this layer. In the
scalp, the lower
portions of the hair
follicles (the
bulbs) are found in
the upper part of
this fatty layer.
The hair follicle
measures about 3-4
mm in length and
produces one to four
hair shafts, each
about 0.1 mm in
width. It is a
complex structure
comprised of three
main layers.
The outer layer,
called the outer
root sheath or
trichelemma,
surrounds the
follicle in the
dermis and then
blends into the
epidermis on the
surface of the skin,
forming the
structure commonly
referred to as the
pore (from which the
hair emerges).
The middle layer,
the inner root
sheath, is composed
of three parts
(Huxley layer, Henly
layer, and cuticle),
with the cuticle
being the innermost
portion that touches
the hair shaft.
Interestingly, the
cuticle is formed by
a layer of
overlapping cells
that interlock with
the cuticle of the
hair shafts shaft
(matrix cells). This
mechanism holds the
hair shaft securely
in place, but also
allows it to grow in
length.
The hair shaft
itself is also
composed of three
layers. The cuticle,
the outer layer just
described, forms the
surface of the hair
and is what we see
as the hair shaft
emerges from the
follicle. The middle
layer, the cortex
comprises the bulk
of the hair shaft
and is what gives
hair its strength.
It is composed of an
organic protein
called keratin, the
same material that
comprises rhinoceros
horn and deer
antlers. The center,
or core, of the hair
shaft, is the
medulla, and is only
present in terminal
hair follicles. The
lower portion of
each hair follicle
widens into a region
called the bulb,
which contains the
matrix cells. The
size of the bulb and
the number of matrix
cells will determine
the width of the
fully-grown hair.

Diagram of hair
follicle histology
(longitudinal view)
Below each follicle
is a small,
collection of
specialized cells,
called the dermal
papillae. The dermal
papillae fit into a
hollow in the
widened base of the
hair shaft. For many
years, scientists
thought that hair
growth originated
from the dermal
papillae. Recent
evidence has shown
that the growth
center extends from
the dermal papillae
all the way up to
the region of the
follicle where the
sebaceous glands are
attached. It is now
believed that the
primary function of
the dermal papillae
is to regulate
follicular growth
and differentiation.
If the dermal
papillae are removed
(this sometimes
happens during a
hair transplant),
the hair follicle is
able to regenerate a
new one, although
the growth of the
new hair will be
delayed.
The normal human
scalp contains about
100,000-150,000
follicles that
produce thick
terminal hair. For
comparison, the
human body has
approximately 5
million follicles
that produce the
fine, vellus hair.
At any given time,
about 90% of
terminal hairs on
one’s head are
actively growing.
This phase, called
anagen, can last
from 2-7 years,
though the average
is about three.
Scalp hair grows at
a rate of about 0.44
mm/day (or 1/2 inch
per month). The
other remaining 10%
of scalp hairs are
in a resting state
called telogen that,
in a normal scalp,
lasts about three
months. When a hair
enters its resting
phase, growth stops,
the bulb detaches
from the papilla,
and the shaft is
either pulled out
(as when combing
one’s hair) or
pushed out when the
new shaft starts to
grow. When a hair is
pulled ou, or falls
out on its own, a
small, white
swelling is found at
the bottom of the
hair shaft. Most
people assume that
this is the growth
center of the hair,
but it is just the
clubbed, detached
lower end of the
hair shaft. The
dermal papillae
remain in the scalp.

The
hair growth cycle
Humans lose about
100 hairs per day;
everyone has a few
hairs stuck to the
comb each time they
comb their hair. The
presence of a large
number of hairs on
the comb, in the
sink, or in the tub
can be the first
sign of excessive
hair loss. One of
the most interesting
things about hair is
that, in contrast to
the commonly held
notion that it grows
as individual
strands, it actually
emerges from the
scalp in groups of
one to four (and
sometimes even five
or six). The reason
for this is that
hair follicles are
not solitary
structures, but are
arranged in the skin
in naturally
occurring groups
called follicular
units. Although skin
pathologists
recognized this fact
in the early 1980's,
its profound
importance in hair
transplantation
surgery was not
appreciated until
the mid-1990’s. The
use of naturally
occurring,
individual
follicular units has
revolutionized
modern hair
transplantation.

3) The Causes of
Hair Loss
A) Facts
All humans are born
with a finite number
of hair follicles.
The diameters of the
individual hairs in
our follicles
increase as we grow
from infancy to
adulthood. However,
no matter what we
eat, what our
lifestyles may be,
or what kinds of
vitamins we take, we
never grow any more
hair follicles.
At puberty, men have
a very low hairline
that usually recedes
to its mature
position by the age
of 20 to 22 and then
stabilizes. In men
with a genetic
tendency to go bald,
this hairline will
continue to recede.
Severe illness,
malnutrition, or
vitamin deficiency
can speed or
exacerbate the
natural hair loss
process, but many
healthy men lose
more hair than
others do. This
natural process is
called androgenetic
alopecia or common
baldness (also known
as male pattern
baldness). It is
only in recent
years, with our
greater knowledge of
genetics and the
chemistry of sex
hormones, that we
have begun to
understand the
causes. It is
important to note
that male pattern
baldness also occurs
in women, but in a
slightly different
form.
Androgenetic
alopecia or male
pattern baldness is
a process that
changes the
follicles that
produce terminal
hairs. Follicles
first produce
thinner, shorter
hairs with weaker
shafts. Eventually,
these follicles
produce only fine,
almost invisible,
vellus hairs, and
they may die out
altogether.
Androgenetic
alopecia requires
three conditions for
its occurrence: the
genes for hair loss,
male hormones in
adequate quantities,
and time.
1) Genes
A gene is a single
bit of chemically
encoded hereditary
instruction that is
located on a
chromosome and
represents a tiny
segment of DNA.
Chromosomes occur in
pairs (humans have
23 pairs), and every
individual inherits
one set of
chromosomes from
each parent. The
genetics of
androgenetic
alopecia is
complicated and hair
loss is thought to
involve more than
one gene. When
several genes govern
a trait, it is
called polygenic.
Genes that are
located on the X- or
Y-chromosomes are
call sex-linked.
Genes on the other
22 pairs of
chromosomes are
called autosomal.
It is currently
believed that the
genes governing
common baldness are
autosomal. This
means that the
baldness trait can
be inherited from
the mother’s or the
father’s side of the
family. The commonly
held notion that
baldness comes only
from the mother’s
side of the family
is incorrect,
although for reasons
not fully
understood, the
predisposition
inherited from an
affected mother is
of slightly greater
importance than that
inherited from an
affected father. The
term "dominant"
means that only one
gene of a pair is
needed for the trait
to show up in the
individual. A
"recessive" gene
means that both
genes must be
present in order for
the trait to be
expressed.
The genes involved
in androgenetic
alopecia are
believed to be
dominant. Just
because a person has
the genes for
baldness does not
mean the trait will
manifest itself. The
ability of a gene to
affect one’s
characteristics,
i.e. be visible in a
particular
individual, is
called
"expressivity."
Expressivity relates
to a number of
factors, the major
ones being hormones
and age, although
stress and other
factors may play a
role. To put it
simply, a man whose
father and uncles
are severely bald
may have minimal
hair loss himself
because the
expression of the
baldness gene is
limited.
None of the genes
responsible for male
pattern baldness has
yet been identified.
This suggests that
any kind of genetic
engineering to
prevent common
baldness is still
many years away.
2) Hormones
Hormones are
biochemical
substances produced
by various glands
throughout the body.
These glands secrete
their products
directly into the
bloodstream in order
to spread them
throughout the body.
These chemicals are
very powerful and
minute amounts of
them have profound
effects upon the
body.
The primary male sex
hormone is
testosterone.
Testosterone and
other related
hormones that have
masculinizing
effects are produced
primarily in the
testicles. This
means that the
hormonal levels that
are seen in adults
do not reached
significant levels
until the testicles
develop and enlarge
during puberty.
These same hormones
are the cause of
many changes that
occur in puberty:
deepening of the
voice, growth of
facial hair,
development of body
odor, change in the
muscular
development, and
change in body
shape. These
hormones that cause
acne and beard
growth can also
signal the beginning
of baldness. The
presence of
androgens,
testosterone, and
its related hormone
DHT, cause some
follicles to regress
and die. In addition
to the testicles,
the adrenal glands
located above each
of our kidneys,
produce androgenic
hormones; this is
true for both sexes.
In females, ovaries,
like testicles, are
a source of hormones
that can affect
hair.
The relationship
between a man’s
testicles and hair
loss has been
recognized for
centuries. In
societies that had
harems, guards were
castrated to prevent
sexual activity
between the guards
and women of the
harem. In all of
those societies, it
was observed that
men who were
castrated before
puberty did not
become bald. Early
in the 20th century,
castration was
common among
patients with
certain types of
mental illness.
Castration seemed to
have a calming
effect, and
noticeably reduced
sex drive in
patients. A
psychiatrist
discovered the
specific
relationship between
testosterone and
hormonally induced
hair loss during
this time.
The doctor noted
that the identical
twin brother of one
patient was
profoundly bald
while the mentally
ill twin had a full
head of hair. The
doctor decided to
determine the effect
of treating his
patient with
testosterone, which
had recently become
available as a drug.
He injected his
patient, the hairy
twin, with
testosterone to see
what would happen.
Within weeks, the
hairy twin began to
lose all but his
wreath of permanent
hair, just like his
normal twin. The
doctor stopped
administrating
testosterone;
however, his patient
never regained his
full head of hair.
The hormone believed
to be most directly
involved in
androgenetic
alopecia is
dihydrotestosterone
(DHT). DHT is formed
by the action of the
enzyme 5-a reductase
on testosterone. DHT
acts by binding to
special receptor
sites on the cells
of hair follicles to
cause the specific
changes associated
with balding. Among
other effects, DHT
decreases the length
of the anagen
(growing) cycle, and
increases the
telogen (resting)
phase, so that with
each new cycle the
hair shaft becomes
progressively
smaller.
In men, 5-a
reductase activity
is higher in the
balding area. Women
have half the amount
of 5-a reductase
overall as compared
to men, but have
higher levels of the
enzyme aromatase,
especially in their
frontal hairlines.
Aromatase decreases
the formation of DHT,
and its presence in
women may help to
explain why female
hair loss is
somewhat different
than hair loss in
males.
3) Time
The mere presence of
the necessary genes
and hormones is
insufficient to
cause baldness. Hair
loss also requires
exposure of
susceptible hair
follicles to the
responsible
hormones. The time
required for hair
loss to start due to
hormone exposure
varies from one
individual to
another, and relates
to a person’s
genetic expression
and to the levels of
testosterone and DHT
in his bloodstream.
Significantly, hair
loss does not occur
all at once, but is
cyclical. People who
are losing their
hair experience
alternating periods
of slow hair loss,
rapid hair loss, and
even stability (no
increase in hair
loss). The factors
that cause the rate
of loss to speed up
or slow down are
unknown.
4) Stress
When the body
experiences stress
caused by a
traumatic
experience,
nutritional
deficiency, or
illness, the rate of
hair loss can
increase. An example
of this occurred in
a man whose
four-year-old child
died. Within just a
few months, he lost
all but the
permanent wreath of
hair around his
head.
Women's hair seems
to be more sensitive
to the effects of
stress than men's
hair. This may be
because women with a
genetic
predisposition
towards hair loss
usually have a
higher percentage of
fragile miniaturized
hair. It is
important to note
that stress
generally causes the
type of hair loss
referred to as
telogen effluvium.
This is very
different from
androgenetic
alopecia. Telogen
effluvium is the
reversible shedding
of hair in the
resting phase when
the body senses that
it needs to divert
its energies
elsewhere.
Therefore, stress
temporarily changes
the amount of hair
that is shed, but
the lost hair is
likely to grow back.

B)Fiction
1) Lack of Blood
Supply
Some assert that a
lack of blood supply
contributes to hair
loss. Bald skin
gradually loses some
of its blood supply
and, consequently,
it becomes thin and
shiny. These
changes, however,
are secondary to the
loss of hair. Hair
follicles are one of
the most rapidly
metabolizing tissues
in the body; their
high metabolic rate
demands an excellent
blood supply to
carry oxygen and
other nutrients to
the cells.
If the blood supply
diminishes, the
follicle cells
wither and die.
Growing hair
requires the proper
nutrition that comes
with a good blood
supply. When hair
follicles are
transplanted into
skin grafts or scar
tissue, both of
which have a
relatively poor
blood supply, the
presence of the
grafted hair causes
the local blood
supply to increase.
2) Clogged Pores
This claim usually
accompanies
microscopic
photographs of an
empty follicle
clogged with a
heaped up waxy
substance that
prevented the hair
from growing. There
is no scientific
evidence that
clogged pores could
interfere with hair
growth. Common sense
is sufficient to
refute these claims.
Why would pores be
clogged on the top
of the scalp and not
on the back and
sides? In addition,
everyone has had an
ingrown hair at one
time or another.
An ingrown hair
occurs when a hair
grows through intact
skin where there is
no opening. If a
hair can force its
way through skin, it
can certainly grow
through soft, waxy
sebum at the bottom
of an empty
follicle. It is also
important to note
that the lubricants
that normally coat
the surface of the
hair shaft are
produced even when a
hair shaft falls
out. Since there is
no hair shaft
surface for these
lubricants to coat,
they pile up in the
bottom of the
follicle space. If
clogged pores caused
baldness, women
would be as bald as
men.
3) Lack of Air
Circulation to the
Head
Folklore says that
men who constantly
wear hats are more
likely to become
bald, as hats
prevent air from
circulating to the
head. Hair follicles
get their oxygen
through the
bloodstream,
however, rather than
from ambient air.
Factors that affect
only the exposed
part of the hair do
not injure the
growing portion of
the hair root. One
exception to this is
that constant
traction on the hair
follicles, such as
from the continuous
wearing of "corn
rows" or very tight
braids, can cause
permanent hair loss.
This condition is
called traction
alopecia, and is
distinct from
androgenetic
alopecia.
4) Preventing Hair
Loss
Many
over-the-counter
lotions and drugs
claim to restore
lost hair. Whether
sold through drug
stores, salons or
mass media, most are
useless. A 1989
Supreme Court
decision prevents
these potions from
being advertised or
sold in the United
States as
medications that
prevent hair loss or
promote the regrowth
of lost hair;
however, such claims
are still made.
Charlatans of every
age have eagerly
seized upon each new
scientific wonder to
profit from a
gullible public.
Excepting cancer and
arthritis, hair
restoration has been
one of the most
fertile areas for
medical nostrums.
For example, in the
same year that the
principle of the
magnetic field was
described,
"magnetic" and
"electric"
hairbrushes for the
prevention and
treatment of
baldness appeared on
the market.
Concoctions that
claimed to be "snake
oils" were also sold
for the treatment of
arthritis and
baldness. In
hindsight, it is
understandable that
an unsophisticated
person, who was
crippled by pain
from arthritis and
who lived at a time
when there was no
better treatment for
his illness, might
be desperate enough
to try "snake oil"
as a treatment for
arthritis. However,
until the Supreme
Court decision
banning their
promotion, ads for
products that
claimed to be able
to restore hair
filled the
television airwaves.
Infomercials
complete with real
doctors, pictures,
and testimonials
promoted these
worthless potions
every day.
Even today, it is
difficult for the
layperson to
differentiate
between fact and
fiction when it
comes to hair loss
remedies. There are
two FDA approved
medications to treat
androgenetic
alopecia. Though
they have limited
benefit, they may be
useful for many.
These two
medications,
minoxidil and
finasteride, are
discussed in detail
in the chapter
titled "Drugs to
Prevent Hair Loss."

C) Thinning of the
hairs
If you think your
hair is thinning,
although you don't
have any real
baldness, it is
important to check
that this is
actually the case.
Try the tug test,
and remember that it
is normal to lose
50-100 hairs a day.
Sometimes thinning
of the hair can be
entirely in the
mind, as a symptom
of depression.
Thinning of hair all
over the scalp
(rather than patchy
baldness) can be due
to various causes.
In the case of
mental or physical
stress, it often
occurs 2–3 months
after the event.
This is because at
the time of the
stress many
follicles enter
telogen (the resting
phase) prematurely,
and are then shed
together at the end
of telogen a few
months later. In
this situation the
hair loss usually
recovers completely.
If you believe your
hair is thinning, do
not assume it is due
to stress. See your
family doctor, who
will be able to rule
out the common
causes (such as
thyroid deficiency
and iron
deficiency). Many
drugs – not just
those listed below –
can cause hair loss,
and the doctor will
be able to check if
this is a
possibility.
Some skin disorders,
such as eczema or
psoriasis of the
scalp, can cause
thinning of the
hair. Usually the
hair grows again
once the skin
problem is treated.
Drugs that may cause
hair thinning are:
Anticancer drugs,
ACE inhibitors for
blood pressure or
heart failure (captopril,
enalapril,
lisinopril),
Blood-thinning drugs
(warfarin), Drugs
for gout (allopurinol),
Antimalarials (chloroquine),
Drugs for epilepsy (valproate
sodium, vigabatrin),
Drugs for
Parkinson's disease
(e.g. pramipexole,
bromocriptine),
Anti-thyroid drugs (carbimazole,
propylthiouracil),
Lipid-lowering drugs
(clofibrate,
bezafibrate),
Anti-acne drugs (isotretinoin).
Often no cause can
be found. In some of
these cases the hair
will recover in
time, but in others
it remains thin. It
is important to keep
thinning hair as
healthy as possible.
If there is no
curable cause, and
the thinning is
distressing, it may
be worth trying
Regaine. Bear in
mind that Regaine
will take several
months to show any
effect, and works in
only a proportion of
cases.

4) How Bald Will I
Be?
For most men, the
first sign of
excessive hair loss
is the appearance of
more hairs than
usual on their comb
or brush. Some men
first notice excess
hair at the bottom
of the bathtub or on
their fingers after
shampooing. Men who
are going to lose a
very large amount of
hair usually see the
first signs between
the ages of 17 and
25. Men whose
fathers or
grandfathers on
either side of the
family were bald,
will probably notice
the hair loss before
someone who has no
apparent family
history of baldness.
Sensitized to the
possibility of hair
loss, they are
waiting for the
process to begin.
As soon as he
notices any sign of
excess hair loss,
the typical man will
rush to a mirror to
do a hair-by-hair
inspection of his
frontal hairline. If
he cannot see any
sign of hair loss,
he may compare his
present hairline
with one from a
recent photo. He
will continue to
closely observe his
hairline every day.
He will also attempt
to keep, a
hair-by-hair count
of the hair on his
comb, his fingers,
or in the tub.
Dark-haired men
notice the hair loss
process earlier that
light-haired men do.
Some men resort to
potions, regimens,
or shampoos. A good
shampoo will clean
your hair, but no
shampoo will stop
the balding process.
These approaches may
offer the comfort of
doing something
during the early
phase of hair loss,
but eventually the
futility of these
measures will become
obvious.
What can a man do?
How can he cope with
the disintegration
of his youthful
looks? What will he
look like without
hair? How will this
affect his ability
to attract a
partner? How will
his professional
life be affected?
Will the change
affect his ability
to gain a promotion?
Will his ability to
sell his product
line to clients be
affected? Anything
that erodes
self-confidence can
have a negative
effect upon all
aspects of life.
The first step is to
make an assessment
of the extent of
hair loss. One way
to do this is to
compare your present
hairline with your
hairline in a recent
photograph. This
will give you an
approximation of the
amount and rate of
your hair loss. An
unknown factor for
most men is the
extent of hair loss
in the crown area.
Looking in a mirror
is one way to
appraise the loss at
the back of your
head. The best way
to accurately assess
the hair loss in
this area is to have
a photo taken of the
back of your head.
For an accurate
reading, the picture
must be taken with a
flash.
Almost every man who
has significant loss
in this area is
surprised by the
results. Another way
is to ask your
significant other,
barber or
hairdresser. If hair
loss is bothering
you, a visit to a
physician who
specializes in hair
restoration is a
worthwhile step. A
thorough medical
history and
examination of the
scalp can reveal the
extent and trends of
your hair loss. With
the use of special
magnifying
apparatuses, a
physician can
specifically measure
the degree of hair
loss in various
areas of the scalp.
This establishes a
baseline from which
your hair loss can
be graded over time.
If you decide to
treat your hair loss
with minoxidil or
finasteride, a
repeat examination
in 6-12 months may
show the
effectiveness of the
treatment. Careful
assessment of hair
loss is critical to
accurate prediction
of the rate and
extent of future
hair loss.
Once you have
confirmed your hair
loss, you should
compare your degree
of baldness with the
standard charts that
follow. These charts
have been adapted
from the patterns
described by Dr.
O'Tar Norwood. They
depict the most
common
configurations of
male pattern
baldness. There are
seven grades of hair
loss in the main
series and five
grades of a
variation called the
A series.
Comparing the front
and back of your
scalp with these
diagrams can tell
you where you stand
now. Discussion with
a knowledgeable
physician can give
you an idea of
future hair loss.
The next step is to
decide whether to
accept your hair
loss or take
measures to stop or
reverse the process.
If you are less than
45 years old, you
might consider using
minoxidil or seeing
a doctor for a
prescription for
finasteride. One
option is to obtain
a hairpiece. Another
option is to replace
lost hair with your
own natural,
permanent hair via
hair transplant
surgery.
