Diet and Hair Loss

Alopecia is the medical or technical name for hair loss. The loss of hair can occur on the scalp or on any part of the body that normally has hair, such as eyebrows or eyelashes. A certain amount of hair loss is normal. The average person normally sheds 50 to 100 hairs every day. The hair shed daily is not necessarily permanent hair loss. Most of the hair we shed grows back. All hairs have a life expectancy of three to six years. At any given time, some of our hair is growing, some is done growing and in the resting stage, and some is in the falling-out stage. Everyone sheds hair at about the same rate, but there are some people, through genetics, who have fewer new hairs that grow to replace those that shed. Pattern baldness or permanent hair loss is simply the result of genetic programming. Increased hair shedding, or temporary hair loss can be caused by a host of different reasons. Some of these reasons include poor nutrition and diet, genes, hormones, age, medications such as chemotherapy, radiation treatment, infections, stress, chemicals used for certain hairstyles, and rapid weight loss. Certain illnesses and diseases can also cause hair loss or hair shedding. Examples include anemia, low thyroid hormone levels, lupus, and sometimes cancer. In most of these cases, hair loss is not permanent.

Nutrition and Dietary Recommendations
Nutritional deficiencies can contribute to increased hair shedding by weakening hair shafts that cause breakage to the hair and slow regrowth. Hair problems that are caused by nutritional deficiencies can be corrected by a proper diet. Principal nutrients that are involved include vitamin A, certain B vitamins, the vitamin biotin, vitamin C, copper, iron, zinc, protein, and water.

Vitamin A
Adequate intake of vitamin A is vital in helping to promote the growth and health of cells and tissues throughout the body, including the hair and scalp. Prolonged vitamin A deficiency can lead to hair loss and dandruff caused by the buildup of cellular debris in the hair follicles. The daily intake of vitamin A for adults is 5,000 IU (international units). The body actually gets vitamin A in two ways: from plant sources in the form of carotenoids, such as beta carotene, that convert to vitamin A in the body. These sources include red, yellow, and orange fruits and vegetables as well as some dark green leafy vegetables. The body also gets vitamin A from animal sources in the form of retinol. Good animal sources include:

• liver
• fish oil
• eggs
• fortified milk
• other foods fortified with vitamin A
