If you need more reasons to consider eating a balanced diet, add good hair. Nutrition experts say that people with certain nutritional deficiencies tend to have dry, stringy and dull hair, and sometimes experience hair loss. Fortunately, nutrition-related hair loss can be restored once the deficiency is addressed. While male- and female-pattern baldness is considered a genetic trait, people experiencing any kind of hair loss should take the time to ensure they are getting good nutrition—for their hair health and general health.
"What you eat or do not eat can affect your hair and skin," says Doug Kalman, RD, a nutritionist with Miami Research Associates. This is important for dieters to keep in mind, Kalman says, particularly those who choose diets that severely restrict calories or eliminate groups of food.
At least one study has shown that people on crash diets experience temporary hair loss because such diets result in poor overall nutrition. Thus, people with eating disorders such as anorexia and bulimia are at risk of temporary hair loss, as well as many other medical conditions. According to Wahida Karmally, DrPH, RD, a spokesperson for the American Dietetic Association, zinc deficiencies, which are associated with hair health, may be a problem among people on low-calorie diets, especially young women. Zinc is found in meat, eggs and seafood.
Kalman says that people on low-fat and non-fat diets are at risk for nutrition-related hair loss because hair needs essential fatty acids. "Essential fatty acid deficiency causes a drying-up of the scalp and skin," he says. "These are vital nutrients that support follicular health. When the follicle is not healthy, hair loss or thinning occurs."
Omega-3 fatty acids can be found in fatty fish such as salmon and mackerel, and in flaxseed oil and macadamia nuts and walnuts. It's recommended that women, in particular, try to eat a food source of omega-3 fatty acids three times a week to maintain skin and hair health.
Biotin, part of the vitamin B complex, is another nutrient associated with hair loss. According to Kalman, people who are eating adequate amount of protein—which includes most Americans—should not have a problem with biotin deficiency, though vegans may be at risk. Good food sources of biotin are eggs, liver and soy.
Karmally says that it's not known if biotin supplements, which are marketed to help with male- and female-pattern baldness, can help with hair loss, and adds that she is unaware of any research indicating that the biotin in biotin hair products, such as shampoos, can be absorbed through the hair or scalp.
Karmally recommends that people experiencing hair loss see a physician, who can help determine the cause of their hair loss, and registered dietician, who can assess their diet and health status. "When you are looking for symptoms of nutrition deficiency in someone with skin and hair changes, it's difficult to pinpoint the cause," she says. "People should pay attention to all aspects of their diet for their total health, as well as their hair and skin."

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:
The reference daily intake of folic acid is 400 micrograms for the average adult. Sources of folic acid include:
The reference daily intake of vitamin Bl2 is 6.0 micrograms for the average adult. B12 is found mostly in animal foods such as:
Seborrheic dermatitis is a common condition that results in excessive oiliness and dandruff on the scalp. This condition usually occurs in infants and the elderly. In infancy this condition is known as cradle cap. Several case studies have shown successful treatment of cradle cap when the mother is given biotin if breast-feeding or given directly to the infant if she is not. The beneficial effects of biotin on the health of hair possibly reflect an ability for the vitamin to improve the metabolism of scalp oil. The reference daily intake for biotin is 300 micrograms for the average adult. Biotin is found in a wide variety of food. Some of the best sources include:
Zinc
Dandruff and hair loss are both conditions associated with zinc deficiency. Zinc is a mineral that promotes cell reproduction and tissue growth and repair. Zinc also functions in the maintenance of the oil-secreting glands attached to hair follicles. The reference daily intake of zinc is 15 milligrams for the average adult. Good sources of zinc include foods of animal origin, including seafood. Eggs and milk also supply zinc in smaller amounts. Whole-grain products, nuts, seeds, and legumes contain zinc, but in a form that is less available to the body.
Protein
Protein is needed by every cell in the body, including the cells needed in normal hair growth. Without adequate protein intake, the body cannot efficiently make new hair to replace the hair that has shed. Protein comes from:
Water
Water is one of the most important nutrients essential for life. Proper hydration is an important factor in healthy hair and in promoting good health. The recommended amount of water to drink each day is 64 ounces or eight 8-ounce glasses. Every cell and every system in the body uses water to function properly. Water is involved in the transport of vitamins, minerals, amino acids, and many other nutrients.
Nutritional deficiencies can be a reason for accelerated hair shedding or temporary hair loss. Conditions that may contribute to poor nutrition and cause hair loss as a side effect include eating disorders such as anorexia. Anorexia can cause severe malnutrition and cause a high proportion of hair follicles to stop their growth cycle. After several months, these hairs shed and the body is not equipped nutritionally to grow back new ones. Normal hair growth returns with adequate nutrition intake.
Rapid weight loss is another reason for accelerated hair shedding. Dropping weight too quickly and/or participating in a fad diet that is not nutritionally sound can cause imbalances in the body and cause increased hair shedding. Following a healthy weight-loss program can prevent this from happening.
Most cases of balding or permanent hair loss results from genetic disposition or heredity influences. Temporary hair loss or hair shedding can result from poor nutrition, among other conditions. Good nutrition can be potentially beneficial to the health of your hair and scalp. If you consume a healthy diet, nutrient deficiencies, as described above, should not be a problem. A healthy diet includes eating most of your calories from the following:
Unlike most diet plans, which are laden with complex, hard-to-follow rules and verboten foods you love but have to live without, the Abs Diet lets you eat the foods you love, keeps your cravings at bay, and helps you control stress -- all at the same time. Here's an example of how you can structure a week of eating. It's not written in stone, by any means: Mix up the meals. Substitute whenever you want. Heck, I don't care if you eat the same thing every day for a week. The purpose of this chart is simply to show you how to follow the principles of the Abs Diet. So enjoy!
