HAIR LOSS, SEX AND IMAGE STRESS
 
by  James Freeman, M.D.
 
According to the American Academy of Dermatology (ADD). there are over
100,000 hairs on the average head. To understand what scientists now
know-how hair thins and eventually dies out completely, it's necessary
to first know how hair grows. Hair, a protein made from tiny cells lining
a hole in the scalp called a follicle, goes through three phases during its
lifetime: anagen , telogen and catagen. In the anagen phase,  about 90
percent of the total scalp/hair population is actively growing at any one
time. This growth cycle is followed by a telogen phase. During this period.
10 percent of the hair rests for three months, then falls out. When the new
hair underneath pushes the old one from its longtime home in the scalp, it
enters the catagen phase. Most doctors agree that losing 50 to 100 hairs a
day is required for hair to continue replacing itself.
 
It is now known that hair grows fastest in the summer, slowest in the winter,
speeds up under heat and friction (massage), but slows down when exposed to
cold. Hair grows the best between the ages of 15 to 30. But, hair growth
begins to wind down sometime between the ages of 50 and 60.
 
Thinning hair, where the hair withers in its follicle to show more scalp
than when a person was younger, can begin at any age after puberty and can
precede actual baldness, where the follicle atrophies stops producing hair
all together-by as much as 10 years or more.
 
What is the causes of post-pubescent thinning hair? In some people, problems
with hormone - producing organs including the adrenals, pituitary, ovaries,
testes and thyroid is the cause of thinning. Your diet is very important for
proper hair growth. According to the AAD, inadequate protein can cause
protein malnutrition, especially among some VEGETARIANS, people on crash
diets that exclude protein, and those with severely abnormal eating habits.
Hair sheds within two to three months as person's body tries to save protein
by shifting the hair growth cycle into the resulting phase. Too much protein
and fat can also cause problems. Scientists have found that when protein
exceeds 15 percent to 20 percent of the daily diet, the body enters a
"negative mineral balance", causing hair to fall out in much the same way
as if it had too little protein.
 
Disease can also be another cause. High fever, severe infecting, thyroid
disease or even a severe case of the flu can cause hair to enter the
resting phase as the body seeks to heal other areas. Cholesterol can build
up in the follicle openings, causing clogs of hardened lipids that choke
hair at the scalp line. In addition, medications including beta blockers,
blood thinners and drugs used to treat gout, cancer chemotherapy,
arthritis, depression, heart problems and high blood pressure can shut
down hair growth all together.
 
TREATMENTS, OLD AND NEW
 
Even after your hair is lost, the root usually remain alive. This suggests
the possibility of new growth.
 
Cortisone tablets taken orally sometimes promote hair growth. Unfortunately,
prolonged use can cause physical or mental side effects, and the new hair
usually falls out when you discontinue the tablets. Other forms of cortisone
are rubbed or injected into your scalp. Their effect is often temporary.
 
Medical researchers in Asia believe that hair loss is caused mainly by
insufficient blood supply to the scalp. The other possibility is excessive
sebum in the scalp which causes pore clogging and malnutrition in the hair
root( "sebaceous Gland Hypothesis", proposed by Dr. Yoshikata Inaba of
The Inaba Aesthetic Surgery in Tokyo).  The so-called 101 hair regrowth
lotion is formulated to attack the problems. 101 became famous after it had
won several international awards, among them, "gold medal" from 14th
International Inventors Exposition in New York (June 4, 1991). According to
Dr. Zhuang-Guang Zhao, the inventor, 101 promotes blood circulation by
removing blood stasis in the scalp and dilating the blood capillaries, it
also remove sebum in the scalp. Unlike other
treatments, it has no side effects, the
active compounds in this lotion are isolated from plants,
According to Newsweek and New York Times reports (references at page 48),
there is no questioning its popularity with the 3 million bald folks in
Japan. Masashi Sada, a popular Japanese singer, said recently on the radio
that the product worked wonders on his head. Millions of men and women in
Asia reportedly have used 101 and 90 percent are said to have found it
effective in hair regrowth and a significant reduction of hair loss.
According to a spokesperson for the 101 products the improved formula
called Fabao 101D will be introduced to USA. But will 101D work on
American heads? since average American diets contain a lot more fat and
protein than their counterparts in Asia. (Editor's note: a brochure can be

Another approach uses minoxidil. This drug was originally developed to treat
high blood pressure and had the unanticipated side effect of stimulating
hair growth, sometimes in unwanted areas. The hair produced is usually
fuzzy, the treatment is expensive, and so far the results are varied
(Editor's note: People should discuss side effects and possible adverse
reactions from using Rogaine with their doctors).
 
Hair transplantation is also an option. The dermatologist
implants tiny plugs of skin, each containing about 10 hairs, into your
scalp. The transplanted hairs falls out in about 3 weeks, but new hairs
are soon produced. Up to four transplantation sessions, at 4-month
intervals, may be needed. This treatment is very expensive.
 
Perhaps the most promising studies come from genetic researchers at Beijing
International Hair Regenerating and Nourishing Research Center(HRNR). For
many years scientists there have searched for the genetic key that would
unlock
the cure for baldness.
 
According to HRNR, the genetic therapy can work one or two ways. The
scientists could make a chemical compound-suspended in a cream or lotion
that is rubbed onto the scalp-which would target itself to the hair loss
gene inside individual follicle cells. The compound would fit itself
securely over the gene, nullifying any further power the troublemaker could
have over hair growth-or the lack thereof. Another option would be to place
a minuscule copy of a normal hair growth gene into a cream or lotion and rub
it into target sites on the scalp.
 
TIPS FOR PROPER HAIR CARE:
 
Each year, Americans spends millions of dollars on hair-care products and
treatments. Unfortunately, some of these efforts are too rough or done
frequently. The result is hair damage rather hair care. Damaged hair stays
damaged until it grows out and is cut off. This can take many months,
because your hair grows only about 1/2 inch each month.
 
Your hair requires gentle handling. Wet hair is especially fragile because
it might become stretched. A natural bristle brush is preferred over a
synthetic one because the synthetic material may cut the hair. Brush the
hair gently from the scalp to disperse scalp oil over the hair. If you
prefer a comb, use a wide-toothed comb to avoid injury to your hair.
 
Certain hairstyles and treatments can cause breakage or root damage. Avoid
excessively tight braiding, buns, or ponytails. do not roll your hair too
tightly in curlers. Teasing and back combing should be done gently or not
at all. To much exposure to sun, wind, or swimming-pool chemicals will dry
out your hair and cause it to knot.
 
The quality of your hair reflects in part the adequacy of your diet:
regular, well-rounded meals are best for you and your hair. Consuming extra
protein or amino acid preparations will not promote hair growth, As
mentioned above, too much protein is bad for hair growth.  Crash diets and
eating disorders such as anorexia nervosa can damage hair
dramatically. Various claims are made for the value of analysis of hair
samples, but the process has no validity and can be considered one of the
many scams aimed at appealing to people concerned about their health.
 
If done gently, daily shampooing will not damage your hair. The
amount of washing will depend on the type of your hair, the weather,
your physical activity, and perhaps even your occupation.
 
For proper washing, wet your hair completely with warm water. put
shampoo on with your hand and massage gently, using your fingers instead
of your nails as you work the lather outward from your scalp. Rinse
thoroughly. use shampoos tailored to your hair type--oily, dry or normal.
Protein shampoos do not penetrate your hair, but they do coat it, giving
your hair more bulk. A protein shampoo acts as a shampoo and conditioner
in one.
Excessive flaking may require dandruff shampoos. Follow your shampoo with
a cream rinse or conditioner. These products lubricate your hair between
washings and help minimize damage from brushing or combing. Those containing
 protein ingredients may also thicken your hair temporarily.
Permanent-waved, straightened, or dye hair needs low pH shampoos.
 
 Towel dry by patting gently. Whenever possible, let your hair dry
 naturally in the air. If a blower is necessary, use it on a low setting and
leave your hair slightly damp. If you brush or comb your hair while it is
wet, you pull out much more hair than you would by gently untangling it with
your fingers and waiting until it is damp or dry before you carefully brush
or comb it.
 
 A styling gel or mousse can give your hair more body or thickness.
They do not necessarily damage your hair, but you may experience extra
dryness, especially at the hair ends.
 
 Hair bleaches chemically alter the melanin granule in the middle
layer of  each hair strand. Despite careful treatment, persistent bleaching
eventually damages even healthy, strong hair shafts, but it does not injure
the roots from which future hair growth takes place.
 
Hair dyes work more like paint by covering hair strands with color
or by mixing with the melanin granules without altering them. Dyes come
in temporary form, which eventually wash out, and semi-permanent and
permanent forms, conduct a patch test to check for possible irritation.
Permanent dyes require prior bleaching. Thus, the dying process does damage
hair.
 
Curling is safest if you twist your hair into pin curls overlight.
Use of hot rollers or curling irons gives the best results for coarse
hair, but they may damage strands or roots when used to excess.  For safe
curling of fine hair, let it air dry and wind it loosely around sponge
rollers.
 
 Permanent waving is safe for healthy hair, but you may find it
results in increased dryness and splitting. Straightening and permanent
waving use the same chemical methods to change the properties of hair
strands. The  initial (waving) solution dissolves a chemical linkage in the
hair. After the hair is arranged in its new, curly configuration,
application of the second solution, the neutralizer, restores the linkage.
Like other aggressive cosmetic treatments, permanent waving can be damaging
when done to excess.
