In order to treat hair loss successfully, it is necessary
to know about hair. This article discusses general facts
about human hair, hair structure and growth.

The average human adult body has an astounding 5 million
hairs of which 100,000 to 150,000 are on the scalp. True
blondes have more hair on the scalp - 140,000 hairs than
brunettes (105,000 hairs) or redheads (90,000 hairs). Hair
is made up of a protein called Keratin. Keratin is also a
constituent of our nails.

* Hair around the world

Hair color and texture differ around the world. Asians have
jet-black hair whereas Scandinavians have varying shades of
browns and reds to the pale blonde. There are generally
three racial groups with three types of hair.

1.Oriental - People from Japan and China have straight and
black hair.

2.Caucasoid - This group is varied and a mixture of
several racial groups. The hair colors range from black to
blonde. The hair can be wavy or straight.

3.African - African people have black hair that is tightly
curled. It is woolly and dry. Heat or chemicals can easily
damage this type of hair.

* Hair structure

Some part of hair is hidden under the skin, while the rest
is seen outside the body. The part of hair hidden under the
skin is the hair follicle. There are tiny blood vessels at
the base of the follicle that provides nutrition to the
hair.

Sebaceous glands secrete sebum that keeps the hair shiny
and waterproof to some extent. At the root of the hair
follicle is the papilla, which is where the hair grows.
Hair follicles are formed when the baby is still in the
womb.

After birth, there is no new growth of hair follicles. The
hair strand itself consists of three layers. The outermost
layer called the cuticle is thin. The middle layer called
the cortex is thick. The cortex provides the hair its
strength, color and determines whether hair will be wavy or
straight.

* Hair Growth

The hair grows at the rate of 12 millimeters every month.
Hair grows the best between 10 AM to 11 AM and again
between 4 PM to 6 PM. It is also generally known that hair
grows faster in summer than winter. Hair grows the best
between the ages of 15 to 30 and slows down from the age of
40 onwards. Both genders start natural hair loss in 50s.

Hair rejuvenation takes place on a daily basis. Hair grows
and sheds. You normally shed 50 to 100 hairs per day. Any
loss above that or visible patches of baldness are a cause
for worry and can be classified as hair loss.
