Prevention from Premature Grey hairs

Grey hair is a familiar sign of ageing. The age when greying starts depends on your genetic inheritance, but around 50 per cent of Caucasians find that half their hair has turned grey by the age of 50.
Loss of hair colour is due to a gradual decline in the production of a pigment, melanin, in the hair bulb. White hair has no pigment, and gray hair has some but not as much as a red, black or brown hair. Not all hairs respond in the same way or at the same time. So the graying process usually is gradual. You can't prevent graying. If you look at individual hairs on a greying head you will see a full colour range, from the original shade to white - all along each hair. and from one hair to another. The first grey hairs usually appears near the temples. Then the greyness spreads to the crown, and later to the back of the head.
Apparent rapid greying may be due to the selective shedding of pigmented hair in a person who already has some grey hairs, which are retained. This kind of shedding usually takes several months. But it can occur in a few days, when the effects are dramatic, since the person's grey hairs would not have been so obvious until the darker hairs were lost. Loss of hair colour before the age of 35 is termed premature greying.
Excessive intake of tea, coffee, alcohol, meat, and fried, oily, greasy, spicy, sour, and acidic foods can reduce the moisture and nutrients reaching the hair follicles and may lead to premature greying.

What are the preventions of premature greying of hairs?
The following steps may lead to prevent premature grey of hairs:

* A drop in melanin production may be caused by a lack of the mineral copper. Eat foods such as crab, oysters, sunflower seeds, cashews and almonds, which have significant amounts of copper.

* To obtain better results, iron & iodine should be taken in form of sea food. Besides fish, which is the main source of iodine, the requirement of this mineral can be met by adequate intake of carrots, bananas & similar other vegetables & fruits. Carrots are especially useful in furnishing fresh blood & maintaining the health of the hair.

* All three of these vitamins, belonging to B group, should be supplied at one time preferably in a form which gives all B vitamins, such as yeast, wheat germ & liver. The three anti-grey hair vitamins can be produced in the intestinal track by bacteria. Thus drinking a litre of yoghurt daily with a tablespoon of yeast before each meal will be an excellent remedy for the prevention & the treatment of premature greying of hair. If one wishes to take tablets of calcium pantothenate & paba, they should be taken in addition to the yeast & yoghurt & not as a substitute for them.

* Avoid foods loaded with artificial colours and preservatives, as these put a strain on your digestive system and can lead to dry, brittle hair and a dehydrated scalp. Too many carbohydrates, such a pasta and bread, can diminish levels of antioxidants in your body that are needed to neutralize free radicals.

* Instead of reaching for a packet of hair dye, try some natural applications. Sage or tea will temporarily coat the hair shaft, hiding the grey. Grey hair tends to be coarse and wiry, owing to a lack of moisture. Apply a hair mask once a week. Olive oil, avocado or banana are excellent nourishing masks.

* Hair cannot really turn white "overnight" - this is an urban myth. Hairs grow with the pigment already inside them. As hair is dead there is no process by which the melanin throughout a hair can be destroyed rapidly by natural causes, rather than chemicals (although it may be bleached by sunlight over many years).
