Diet, Nutrition, and Hair Loss

One key factor in maintaining a growing protein on a part of one’s biological body is obvious: one must maintain a healthy diet. Although certain factors have been definitely identified as contributors to hair loss, we must keep in mind that hair is part of the complete biological system of the human body. Being a system, dysfunctions in one part of the system can contribute to dysfunctions in other parts; chain reactions occur when one part of the body malfunctions, causing other parts within the system to falter. To maintain optimum health, it is best to maintain a healthy diet and regular exercise regimen.

Defining exactly what a healthy diet is when it comes to preventing hair loss can be a little more complex. Principally, the main vitamins, minerals, and nutrients that one must ingest in some form to maintain healthy hair are vitamin A, all B vitamins-particularly vitamins B-6 and B-12, folic acid, biotin, vitamin C, vitamin E, copper, iron, zinc, iodine, protein of course, silica, essential fatty acids (EFA’s, formerly known as vitamin F) and last but not least one must consume water. There are also certain foods that may cause dysfunctions that will contribute to hair loss.

The best way to maintain a healthy vitamin and mineral intake is a good diet. It is not necessary or advisable to go out and buy a bunch of over-the-counter vitamin supplements in order to achieve your suggested nutritional levels. Many over-the-counter vitamins are chemically processed and are not completely absorbed into the system. It is also easy to overdose oneself with over the counter vitamins particularly when taking supplements of fat-soluble vitamins and minerals, causing toxicity and adverse reactions. The likelihood of doing this is far less with food; therefore it is always best to obtain the bulk of your vitamin and mineral requirements from whole foods.

Vitamin A is a key component to developing healthy cells and tissues in the body, including hair. Additionally it works with silica and zinc to prevent drying and clogging of the sebaceous glands, the glands vital to producing sebum, which is an important lubricant for the hair follicle. Vitamin A deficiencies commonly cause thickening of the scalp, dry hair, and dandruff. Air pollution, smoking, extremely bright light, certain cholesterol-lowering drugs, laxatives, and aspirin are some known vitamin A inhibitors. Liver, fish oil, eggs, fortified milk, and red, yellow, and orange vegetables are good sources for vitamin A, as are some dark green leafy vegetables like spinach. Be particularly careful if you take vitamin A supplements, as vitamin A is fat-soluble, allowing the body to store it and making it easy for the body to overdose on vitamin A. Vitamin A overdoses can cause excessively dry skin and inflamed hair follicles, and in some cases ironically can cause hair loss. If you choose to take supplements of this vitamin, consult with a specialist first. As mentioned above, the likelihood of overdosing by achieving your vitamin A intake by food sources is almost nil, so it is best to attempt to achieve this at all costs.

B-vitamins work interdependently and therefore all levels of B vitamins need to be sufficient in order to maintain proper health. Vitamins B-6, folic acid, biotin, and vitamin B-12 are all key components in maintaining healthy hemoglobin levels in the blood, which is the iron-containing portion of red-blood cells. Hemoglobin’s primary function is to carry oxygen from the lungs to the tissues of the body, so if these vitamins were deficient in one’s body, then hair and skin would indeed suffer. Fortunately some of the tastiest foods contain these vitamins. Vitamin B-6 is found in protein rich foods, which is excellent because the body needs a sufficient amount of protein to maintain hair growth as well. Liver, chicken, fish, pork, kidney, and soybeans are good sources of B-6 and are relatively low in fat when they are not fried. Folic acid is found in whole grains, cereals, nuts, green leafy vegetables, orange juice, brewer’s yeast, wheat germ, and liver again. Meat, fish, poultry, eggs, and other dairy products meanwhile provide healthy amounts of B-12. Biotin deficiencies are rare unless there is a severe case of malnutrition or a serious intestinal disorder, since a healthy gut produces biotin through good bacteria found there.

Note: if you have a known intestinal disorder and are plagued by hair loss, ask your doctor about biotin deficiencies and possible solutions. Vitamin C is responsible for the development of healthy collagen, which is necessary to hold body tissues together. A vitamin C deficiency can cause split ends and hair breakage, yet this is easily reversible with an increase to normal vitamin C levels. Vitamin C can be found in foods such as fresh peppers, citrus fruits, melons berries, potatoes, tomatoes, and dark green leafy vegetables.

Vitamin E is necessary to provide good blood circulation to the scalp by increasing the uptake of oxygen. Vitamin E is derived from foods such as green leafy vegetables, nuts, grains, vegetable oils, and most ready-to-eat cereals, which are fortified with vitamin E. Vitamin E deficiencies are rare in people in North America and Europe. In the rare cases of vitamin E deficiency, usually caused by the inability to absorb oils and fats, dietary supplements are available.

Copper is a trace mineral that is also necessary in the production of hemoglobin. Hemoglobin as mentioned earlier is vital to the process of carrying oxygen to tissues such as the hair, and obviously hair is alive cannot grow without proper oxygen, yet it does not breathe as other components of our body do, because the oxygen must get to the shaft of the hair. Good sources of copper are liver again, seafood, nuts, and seeds. Another key mineral vital in the production of hemoglobin is iron. Iron is found in two forms, heme and non-heme; heme iron is much easier to absorb into the system. This is where the problem lies. Of course most people know that red meat is a good source of iron, however red meat is non-heme iron and is difficult for the body to absorb, as are many iron supplements. Good heme iron sources are green leafy vegetables, kidney beans, and bran. Additionally, one can increase the absorption of non-heme iron into the body by consuming non-heme food sources and vitamin C sources in the same meal.

Zinc is another vital component to healthy hair, being that it is responsible for cell production, tissue growth and repair, and the maintenance of the oil-secreting glands of the scalp. It also plays a large role in protein synthesis and collagen formation. For this reason, zinc is important for both hair maintenance and dandruff prevention. Most Americans are deficient in zinc. Most foods of animal origin, particularly seafood, contain good amounts of zinc; oysters are particularly rich in zinc. Zinc is also found in eggs and milk, although in much smaller amounts. Zinc from sources such as nuts, legumes, and natural grains is of a different type than those found in animal sources and is not easily used by the body, although oats are a good source of zinc that is readily used by the body. Protein is found in most of the aforementioned animal source foods, particularly meats, fish, milk, cheese, eggs and yogurt. There is no need for a person eating the average Western diet to eat additional protein. Too much protein, even though hair is made of protein, will not improve hair growth and may cause other health problems.

A challenge for vegans is to maintain healthy levels of protein, being that complete proteins containing all nine essential amino acids necessary are found mostly in animal sources. Legumes, seeds, nuts, grains and vegetables do not contain the same form of protein necessary for a healthy body. There is only one common non-meat source for complete protein, and that is the soybean. Fortunately, soybeans have been made into tofu and texturized vegetable protein (TVP) so that they can be made into various dishes. Additionally, one may eat from a wide variety of vegetable sources in order to obtain all the essential amino acids.

Iodine is vital to the growth of hair. Sheep farmers long ago discovered that vegetation void of iodine due to iodine-depleted soil will adversely affect the growth of wool in sheep. Likewise, our hair needs iodine to grow. Iodine is synthetically added to table salt, however in this form it is not assimilated well into the body and can therefore cause iodine overload. An excess of iodine in the body can adversely affect the thyroid. It is best to use non-iodized salt and retrieve your iodine from natural food sources. These include seaweed, salmon, seafood, lima beans, molasses, eggs, potatoes with the skin on, watercress and garlic.

One of the most difficult nutrients vital to hair growth to get in one’s diet is the trace mineral silica. Silicon is a form of silicon and is the second most abundant element in the earth’s crust, second only to oxygen. The Earth provides everything we need for health, and with silicon being so abundant, it would seem that there would never be a problem with silica deficiency. Unfortunately, trace minerals are rare in Western diets because our food is processed and our soil depleted by chemical treatments so often that trace minerals are lost. Silica is vital to the strength of hair, and although it will not necessarily stop hair from falling out from the follicle, it will stop hair breakage. It works by stimulating the cell metabolism and formation, which slows the aging process. Foods that are rich in silica are rice, oats, lettuce, parsnips, asparagus, onion, strawberry, cabbage, cucumber, leek, sunflower seeds, celery, rhubarb, cauliflower, and swiss chard. Note that many of these foods, particularly rice, are a large part of Asian diets and Asians tend to have the strongest and healthiest hair. Be sure to seek out all the above foods from sources that grow food organically, as this is vital to obtaining the trace minerals that are usually not present in North American soil and therefore not in American foods. Additionally these foods should be eaten uncooked, or in the case of rice-unwashed, as trace minerals are easily cooked and washed away.
