Each hair grows at the rate of about half an inch a month.
The hair's average life span is 4-5 years before replaced hair can be found on
an average head. 90% of these are in their growing phase; this is
known as the Anegen phase and is followed by their resting phase
(Telogen). After this a new hair starts to grow in the same
follicle, pushing out the old one. The period of change between the
old one and the new one is called the Cetacean phase.
When there is a delay in this stage of growth, the result as we
see it is hair loss. The time to be concerned about hair loss is
when we lose more than one hundred hairs a day. It is when those
hairs are not replaced that visible thinning occurs. This is called
Telogen Effluvium. At this stage there is cause for concern.
Thinning hair can indicate an internal dysfunction. Should this
be the case one should seek help. By finding the underlying cause
corrective measures can be prescribed to counteract the
Nutrition and hair
A healthy diet is essential for a
healthy growth system in the body. Proteins, vitamins, minerals and
water provide the hair's more essential components. That is not to say that
fats, carbohydrates and other nutritional items are not significant,
but their presence is not critical. If you consider the large number
of vitamins, amino acids and minerals necessary for healthy growth
of hair and skin, you can begin to appreciate the complexity of the
body's task in keeping itself healthy.
Although proteins account for an amazing 97% of the structure of
the hair, only 15-20% of the nutritional intake of proteins provides
for the replacement of the hair and skin. The hair's physical
condition (i.e. colour and texture) can change during protein and
Most vitamins and minerals are concerned with the structure,
pigmentation and keratinisation of the hair. All falsoluble vitamins
play an active part in providing the nutritional materials for
healthy growing hair. Vitamin A-excess or deficiency can result in
abnormal keratinisation of epithelium cells. Excess of Vitamin A or
D will result in hair loss.
Vitamin B: Job related B-Vitamins provide the body with energy by
converting carbohydrates into glucose, which the body 'burns' to
produce energy. The B-Vitamins are vital in the metabolism of fats
and proteins. They may also be the single most important factor for
health and nerves. Lack of B-Vitamins can lead to graying hair,
baldness, acne and other skin related problems.
B-Deficiency can cause (Vitamin B2): hair loss, scabbiness of the skin
and other B-Deficiencies such as poor appetite, insomnia,
neuritis, anemia, constipation or high cholesterol.
The graying of hair (B5 Hyper pigmentation and epidermal changes
- lack of B12) All B-Vitamins are natural constituents of brewer's
yeast (the richest source of the B-complex group), liver, whole
Sleeping pills, insecticides and estrogen create a condition in
the digestive tract which can destroy the B-Vitamins. Certain
B-Vitamins are lost through perspiration.
Mineral content is between 1% and 2% and fluctuates according to
sex, diet, time of the year and environment factors. The content of
zinc found in the soil, plants and food affects the body's
metabolism of zinc.
Selenium, a trace element found in the hair, has numerous uses,
including the control of dandruff. Sources of this helpful element
are found in seafoods, meats, milk products, cereals and whole
grains (especially wheat).
