with their hair. There's nothing more stunning than long,

gives women many options when it comes to styling and
creating new looks. Even though the hair is a dead tissue
, it suffers from numerous hazards mirroring hair problems.
Every one who desire to be beautiful and takes hair care
should understand the basics of hair |
Hair
is composed of a protein substance called keratin. The average
adult human being has about 100,00 to 150,000 hairs on the
scalp. skin. The colour,type, and sizes varies from person
to person and race to race.

| Structure
of the Hair Hair is grown
from the root, which is underneath the skin and embedded
in a bag-like structure called follicle. Tiny blood
capillaries convey the necessary nutrients to the base
of the follicle called papilla where the manufacture
of hair takes place. Adjacent and attached to the follicle
is the sebaceous gland that secretes an oily substance
called sebum, which is for the lubrication and protection
of the skin and hair. The colour to the hair is being
given by the melanin pigments which are synthesized
by a special cell in the scalp. |

Life Cycle of hair
Each hair follicle undergoes a cycle
of activity. The hair grows to a maximum length, then
hair growth ceases and the hair is shed and replaced
The duration of each hair cycle of an individual differs
largely with age, mental stress level, blood circulation
and nourishment and other pathological factors. The
active growth period called anagen phase of the hair
cycle may last up to 5 years and the average hair
growth is about 12mm in length per month. Hair grows
and is shed at a normal rate of 50 to 100 hairs daily.

Life cycle
of Hair |
The hair growth cycle has three distinctive phases:
Anagen:
the period of active growth
A scalp hair will grow actively for between
one and a half and seven years (three years being an average
growth period). The average growth rate is about half an inch
per month. On average 85% of follicles are in the anagen stage.
Catagen:
the period of breakdown and change
This is the end of the active growth period,
The hair stops growing and becomes detached from the base
of the follicle forming a club hair. The hair bulb begins
to break down, resulting in the follicle becoming shorter.
This period of breakdown or change lasts about three weeks.
As the inner root sheath breaks down, the hair remains in
the follicle due to its shape. On average, 1% of follicles
are in the catagen stage.
Telogen:
the resting stage before resumption of growth
The section of remaining root sheath still in
contact with the papilla is known as the secondary or root
germ. It is from this germ that a new hair can grow. The shortened
follicle rests for about three months. The hair may be brushed
out at this time or at the onset of anagen. On average 14%
of follicles are in the telogen stage.
After the telogen stage the cycle returns to
anagen and the root germ begins to grow downwards and forms
a new bulb around the dermal papilla. It is the lower end
of the germ that forms the new bulb, producing a new hair.
The upper part of the germ forms the new cells that lengthen
the follicle below the club hair. The new hair may push the
old hair out.
Fact
:
The average daily loss of hair on the scalp is between fifty
to hundred hairs. If the loss is over hundred daily, hair
loss will exceed replacement, and you eventually
become bald.
Hair growth is fastest from the age of sixteen to the late
twenties. New hairs grow faster and the growth rate slows
down with the increasing length
The average number of hairs on the scalp of an adult is
100,000. to 140,000
Thus the hair is affected
by the state of the nervous system and by the condition
of the circulatory system. As such it is very much interrelated
to the functioning of the entire human organism: body, mind
and emotions. When you ponder on the opulence of the nerve
and blood supply to the head, you will have no difficulty
appreciating that whatever adversely affects them, will
in the long term, be to the detriment of the hair.
