Biotin
Biotin is a member of the B complex vitamins that work together in the body and are essential for the growth of healthy hair. A biotin deficiency results in hair loss and dry, dull hair. Food sources for biotin include liver, egg yolks, cauliflower and oatmeal. For the ultimate treatment for hair loss aim to include the other essential B vitamins in your diet such as thiamin, riboflavin, niacin, pantothenic and folic acid.
Iron
An iron deficiency means that your body is not producing enough red blood cells it requires to carry energy-sustaining oxygen to every tissue in your body. Symptoms of an iron deficiency include fatigue, depression and hair loss. Iron is needed for blood and oxygen to flow to the scalp. This helps stimulate the hair follicles so that healthy hair can begin to re-grow after hair loss. Good sources of iron include apricots, black-eyed peas, soybean, liver, clams, oysters, berries, dried fruits, figs, pine nuts and whole grain breads.
Vitamin C
Your body needs vitamin C to absorb iron. In "The Food Bible," the author Judith Wills says to eat vitamin C sources such as citrus fruit after an iron-rich meal. Other vitamin C sources to include in your diet for healthy hair includes tomatoes, green peppers, dark green leafy vegetables, broccoli, cantaloupe, Brussels sprouts, potatoes and asparagus.
