There is no doubt that there are a number of factors which undeniably contribute to hair loss . But having said that it must also be acknowledged that hair on the human body is just one part of the entire biological system. In any system, there is bound to be the inevitable breakdown and one breakdown in the system can sometimes cause a breakdown in another part of the system. The human body's biological system is no different. For anyone to remain in excellent health it is essential for a healthy diet to be maintained and this should always be coupled with an appropriate and regular exercise programme.

The definition of a healthy diet is a subject about which there has been numerous and ongoing debates over the ages. When it comes to the relationship between a healthy diet and the prevention of hair loss the same applies. There is a never-ending debate on the subject. There is general acceptance, however, that there are groups of minerals, vitamins and general nutrients, which are essential in order to maintain healthy hair.

The vitamins are A , B , C and E with emphasis on B-6 and B-12 , folic acid, biotin, copper, iron, zinc, iodine, protein, silica and essential fatty acids (EFA's , formerly known as vitamin F.). One of the things which is overlooked by a great many people is the consumption of water. The actual amount of water to be consumed is also an open debate, but it is generally accepted that four to eight standard glasses per day is sufficient.

There is no doubt, the ideal method of obtaining the essential minerals vitamins and general nutrients is through the appropriate diet. Particular emphasis however, should be placed on the word ideal. Today, there is a school of thought, and it is one with which I happen to agree, that it is extremely difficult for the average person to obtain the necessary level of essential minerals vitamins and general nutrients through diet alone. The use of supplements to replace any shortcomings in a persons diet remains as what can best be described as a controversial subject. Personally, I have been taking various supplements for some years now and have always found them to be beneficial providing they are used sensibly and according to directions. Any doubts or inquiries regarding the use of supplements should be directed to your doctor.

One of the fundamental elements in developing and maintaining healthy cells and tissues in the body is vitamin A and this of course includes hair. Sebum provides vital lubrication to the hair follicle and is produced by the sebaceous glands. Vitamin A. together with silica and zinc work in conjunction in the prevention of drying and possible clogging of these glands, which are vital to the production of sebum.

If there are any deficiencies in vitamin A. it is quite common for this to cause dry hair, dandruff and possible thickening of the scalp. Some of the best natural sources for vitamin A. are dark green leafy vegetables, (for example spinach), liver, fish oil, eggs, and some red, yellow, and orange vegetables. On the contrary, some of the things which are known to inhibit vitamin A. are smoking, air pollution, laxatives, and aspirin. It is also thought that some cholesterol lowering drugs, may also inhibit vitamin A but this should of course be referred to your doctor.
