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.
