Hair LossWhy You Have Hair Loss
Hair is the fastest growing tissue of the body, made up of
proteins called keratins. Every strand of hair is made up of three
layers: the inner layer or medulla (only present in thick hairs);
the middle layer or cortex, which determines the strength, texture,
and color of hair; and the cuticle, which protects the cortex.
Hair grows from roots, which are enclosed in follicles. Below
this is a layer of skin called the dermal papilla, which is fed by
the bloodstream carrying nourishments vital to the growth of hair.
Only the roots of hair are actually alive, while the visible part
of hair is dead tissue, and therefore unable to heal itself.
It is vital then to take care of the scalp and body in order to
perpetuate hair growth and maintenance. Expensive treatments that
claim to treat the visible hair and nourish it therefore are
usually no more than bogus claims made to sell products. Hormones
called androgens, usually testosterone, can cause hair follicles to
shrink, causing thinning of hair or eventual hair loss. Reportedly
only bone marrow grows faster in our body than hair does. The
average scalp contains 100,000-150,000 hair follicles and hairs,
with 90% growing and 10% resting at any given time.
Hair actually grows in three stages:
* Anagen
* Catagen
* Telogen The anagen phase is the phase where hair is actively
growing, and of course this phase is longer for follicles in the
scalp than anywhere else on your body, and lasts longer for women
than men.
It is natural for follicles to atrophy and hair to fall out, and
this is called the catagen phase. This phase is only temporary, and
eventually the follicle enters the telogen phase where it is
resting. These are the 10% at rest mentioned above.
Normal anagen phases last approximately five years, with catagen
phases lasting about three weeks, and telogen phases lasting
approximately 12 weeks. As you see it is natural to lose some hair.
Natural hair loss is considered to be in the range of 100 hairs per
day. It is not apparent to most people that hair is actually being
lost until more than 50% of a person's hair is actually lost.
Although both men and women can suffer significant hair loss, over
50% of men will suffer with Male Pattern Baldness (MPB), also known
as androgenetic alopecia, at some point in their lives. The reason
behind hair loss is a genetically inherited sensitivity to
Dihydrotestosterone (DHT) and 5-alpha-reductase. The enzyme
5-alpha-reductase converts testosterone, a male hormone, to DHT,
the substance identified as the end-cause for hair loss. Despite
any genetically inherited sensitivity, it is possible to lessen the
amount of hair loss some people will experience; this done through
use of supplements and hair cleansers that eliminate excessive DHT. Also,
taking vitamins and minerals that strengthen hair will slow down
the inherited tendency for hair loss. Finally, watch for stressful
situations that last for months and take counter measures by
increasing you hair supplements. Rudy Silva
