Hair Loss and Vitamins
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. Many people 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.
