Diet, Nutrition and Vitamins for Hair Loss - Part 2

Diet, Nutrition and Vitamins for Hair Loss
Diet, Nutrition and Vitamins for Hair Loss - Part 2
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.

Essential Fatty Acids (EFA’s) are fatty acids that are needed by the body yet not produced by the body. EFA’s are a key component to healthy skin, hair and nails. Common skin diseases, such as those discussed later in this book like eczema and seborrhea, are in part caused by deficiencies in EFA’s. Including deep-water fish such as salmon, sardines, mackerel, trout, or herring approximately three times a week will provide sufficient amounts of EFA’s. However, if for some reason you cannot eat deep-water fish or have an extreme dislike for it, it may be necessary to take a supplement to obtain the required amount of EFA’s.

Last but not least, make sure to include the proper amount of water in your diet. Water is vital to proper hydration, which is necessary in order for all nutrients to be utilized properly by the body, not to mention the proper function of every cell in the body including hair follicles. The suggested amount of water intake daily is eight 8-ounce glasses of water a day, or 64 ounces a day.

The effects of high-fat diets and the increase of DHT (Dihydrotestosterone), a chemical produced by the body found to cause hair loss, is not conclusive at this time. However, there does seem to be a connection; as societies that consumed relatively low-fat diets such as pre-World War II Japan experienced almost no pattern baldness, whereas in post-World War II Japan there is an increase in pattern baldness as their society consumes a higher fat diet. In fact, Asian and African men in their native countries traditionally suffer very little Male Pattern Baldness (MPB). Although when the same peoples come to North America, they begin to develop MPB. Because people of all races and ethnicities tend to develop MPB or androgenetic alopecia, yet do not exhibit these tendencies before moving to America, changes in diet may be a leading contributing factor. Diets high in fat do increase testosterone, which is the main component in DHT. More research needs to be done on this topic to reach conclusive evidence, although it certainly could not hurt to lower one’s fat intake.

Fiber is vital to making sure undigested food moves through the body and to the bowels properly. Failure of foods to move through the bowels in a reasonable amount of time can cause fermentation of undigested food in the bowels and blocking of nutrients being absorbed through the body. Beyond causing degrees of malnutrition, this can also cause a level of toxicity that will overwork systems in the body such as the adrenal glands and contribute to hair loss. Healthy amounts of fresh vegetables, fruits and legumes consumed daily will ensure a proper amount of dietary fiber.

Although nutritional remedies were those that were discussed here, supplements can be used if one feels they are simply unable to eat properly due to work schedule or dislike of certain foods. Nutritional supplements containing these same vitamins and minerals can be taken, with the exception of water of course. Be sure to always take supplements that are naturally chelated, meaning that the supplements were developed in a natural base. This will ensure that the supplements you consume will be more readily absorbed in the body. There are some cautions to taking supplements of certain vitamins and minerals, particularly those that are fat-soluble because the body stores them.

Vitamin A can be highly toxic and supplements of vitamin A should be avoided unless recommended by a doctor. It is best to achieve one’s vitamin A requirements either by food or through a naturally chelated multivitamin. Also remember that smoking and second hand smoke can cause blocking of vitamin A assimilation, so it is best to avoid smoking and remove one’s self from areas and situations where second hand smoke is present if at all possible.

Vitamin E supplements should always be taken at 400 i.u. per day to start and work your way up to 800 i.u. Always take vitamin E in its natural form, which is d’alpha tocopherol. Avoid taking vitamin E supplements in the synthetic form dl’alpha tocopherol, which is derived from petroleum and is less available for assimilation into the body. If you have high blood pressure or other serious illnesses, consult a physician before taking vitamin E supplements.

Zinc is one fat-soluble mineral that can cause harm if an overdose is taken. Zinc can rob the body of copper, mentioned above as a key nutrient in hair growth and health, not to mention in other functions of the body. Zinc supplements should be taken in low doses, such as 5mg at a time. These can commonly be found in the form of zinc lozenges designed for sore throats. There is a “trick” to tell if you are taking too much zinc. When the zinc levels in the body have surpassed the level that they can be used, a metallic taste begins to form. If you pay attention to the metallic taste, you will know when enough zinc has been consumed, and you can then stop consuming zinc immediately.

Iron supplements are not recommended unless a doctor has diagnosed you with a severe iron deficiency. If you do take an iron supplement, avoid ferrous sulfate, which you will find as the most common over-the-counter iron supplement in drug stores. Ferrous sulfate is hard for the body to assimilate, and because iron is not water-soluble it will sit in the body and can cause severe liver problems over time. Further, ferrous sulfate causes constipation, which can trigger a great deal more problems besides being extremely unpleasant. One iron supplement that does not contain ferrous sulfate is called Floradix and is available in both liquid and pill form.

Since there are so few foods to mention that are grown in North America and contain a good amount of silica, supplements may truly be needed. Horsetail is an herb that is a rich source of silica. It is highly important to never take horsetail directly however, or take a supplement made from unprocessed horsetail, as this herb can be toxic when ingested whole, ground, in tablets or capsules. Horsetail must be taken in an aqueous extract of the herb only. Ask someone at your health food store or someone knowledgeable about herbs to help you find this form. Silica gel is suspended in water, although it is not an aqueous solution and should be avoided. Nettle is also a good source of silica and Nettle Root Extract is readily available at health food stores.

Supplements of Essential Fatty Acids (EFA’s) are easily found in most health food stores and even many supermarkets and pharmacies. These include Evening Primrose Oil, Wheat Germ Oil, Flaxseed Oil, Cod Liver Oil, and other oils from deep-water fish. It is not recommended to rely on Cod Liver Oil as a source for EFA’s because it contains high levels of vitamins A and D, and the amount of Cod Liver Oil necessary to achieve proper amounts of EFA’s would cause overdosing on these vitamins. The recommended supplements are Evening Primrose Oil and Flaxseed Oil. Both these oils are available in oil form or in capsules. Keep in mind that high amounts of saturated fat blocks the effectiveness of EFA’s, counteracting their effectiveness, so there needs to be adjustments to your diet if there is a high amount of saturated fat in it.
