| As most people know, everyone loses hair. It's normal.
Because every hair follicle on your head goes through a growing phase,
called the anlagen phase, and a resting period, called the deluge phase.
In a person with a healthy, full head of hair, hair
loss of up to 50 hairs a day is deemed normal. People who are suffering
from the onset of male pattern baldness lose up to 250 hairs a day.
Why?
In male pattern baldness sufferers, the
hair follicles enter their resting phase more frequently, and for longer
periods of time. When the hair follicles do produce hair again, it is
smaller in size and lighter in color, and as the cycle repeats, the hair
become so small and so absent of pigment that it is called lanugos-type
hair, also known as peach fuzz. As time progresses, the follicle will
cease to produce hair entirely and baldness results.
Medical science knows the cause of male
pattern baldness is due to hormonal activity that is genetic in origin:
Testosterone in the scalp breaks down and one of its by-products, dihydrotestosterone
(DHT), interferes with the hair follicle, causing it to atrophy (resulting
in smaller hairs of less pigment), and finally, to whither and die, when
it will produce no hair at all.
What medical science doesn't know is exactly
why some men with high testosterone levels (marked by heavy beards, an
excess of body hair and deepness of voice) do not succumb to male pattern
baldness, while others, often with lower testosterone levels, do. Nor
is it understood why male pattern baldness affects the hair follicles
on top of the head and not those on the back and sides. In other words,
medical science understands the "hows" of the process; they
just don’t understand the "whys." And that has hampered attempts
to stop excessive hair loss.
How?
Someone who is searching for absolute truth
in determining which singular substance can reduce excessive hair loss
may well end up being very disappointed, because no one ingredient has
proven effective for all individuals, all the time. What is probably more
correct is that individuals respond to different treatments in different
ways. What may work for one person may be ineffective in another, and
so on. What is encouraging is that today there exist alternatives, some
of which have proven effective for some people, some of the time.
Facts Pertaining to Hair Loss
If the drainage hole of your bathroom is
clogged with your hair whenever you take a shower, well, don't lose sleep
over it. And if you are alarmed over losing up to 50 to 100
strands of hair a day, don't worry about it at all, it's perfectly normal!
As you get older, you only tend to lose more hair, progressively.
Hormonal changes in your body brought on
by the ageing process, along with the heredity factor, means that some
people lose more hair than others as they age. In men, this type
of hair loss, is called "male-pattern balding", and results
in a receding hairline, and/or thinning of hair at the top of the head.
Similarly, some women experience mild "female
pattern balding". That normally entails a thinning of hair
over the top of the scalp. Women with female pattern balding, typically,
start losing hair between the ages of 25 and 30. However, hair loss
in women is less prominent than in men.
We could lose hair after certain types
of fevers, major surgery and/or infection. Women on diet or those
who have a heavy menstrual flow, may also suffer severe hair loss due
to the lack of protein, iron and zinc in their bodies. |
