Copper is a trace mineral that is necessary in the production of hemoglobin.
Hemoglobin is vital to the process of transport of oxygen to tissues, such as hair, and obviously hair is alive can not grow without proper oxygen, although not breathe, like other parts of our body, but the oxygen must reach the hair shaft. Good sources of copper are liver again, seafood, nuts and seeds.
Another key mineral vital in the production of hemoglobin is iron. Iron can be found in two forms, heme and non-heme; heme iron is more easily absorbed in the system. Herein lies the problem.
Of course most people know that red meat is a good source of iron, although red meat is non-heme iron and is difficult for the body to absorb, as are many supplements.
Good heme iron sources are green leafy vegetables, kidney beans, and bran.
Additionally, one can increase the absorption of non-heme iron in the body by consuming non-heme food sources and sources of Vitamin C in the same meal.
Zinc is another vital component for healthy hair, being that is responsible for cell production, growth and tissue repair and maintenance of the oil-secreting glands of the scalp.
It also plays a very important role in protein synthesis and collagen formation. Therefore, the zinc is important for the maintenance of hair and for preventing dandruff. Most Westerners 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 smaller quantities.
The zinc from sources such as nuts, legumes, and natural grains is of a different to those found in animal sources and is not easily used by the body type, although oats are a good source of zinc that is readily used by body.
