Nutrition Affect Hair?

Whoever coined the phrase ‘you are what you eat’ was probably thinking about the health of their hair when they said it!

With the exception of our bone marrow and the cells that form the lining of our stomach, the cells of the hair bulb reproduce at a greater rate than any other body cells. Because of its rapid growth, hair is very sensitive to internal or external changes that may affect our body. Hair loss or dull, dry hair is often the first indicator to a developing internal disturbance. It’s little wonder then that the condition of our hair is directly affected by the foods we eat or don’t eat.

A gradual thinning of the hair in an ‘all over’ way may reflect low iron, zinc, or calcium levels. It could also herald the onset of a physical disorder such as diabetes or problems of the thyroid gland. With low iron, zinc, vitamin C deficiency, or a thyroid disturbance, the hair is very often dry, brittle and lustreless. Hair texture and colour may also be altered with some deficiencies.

In over 70% of women who present with a thinning hair problem, a low iron level is either the primary or most frequently underlying additional cause of the condition. If a woman is vegetarian, or consumes little iron-rich foods and has a history of heavy periods, she should intermittently supplement her diet with a nutritional iron formula.

Proteins are required by our body for tissue and cell repair and growth. The average daily diet should contain 30% proteins from various sources to maintain good health. Proteins account for about 97% of the structure of our hair, and 15-20% of our protein intake is utilised for skin and hair replacement.

In this country most people would have an adequate protein intake. However, some groups such as the elderly, those with physical, or chronic psychiatric disabilities, young children, people who are too poor to purchase high protein foods, or those ignorant of their nutritional requirements can be at risk.

The ‘tea and toast’ routine of some elderly folk is well documented; they and those with disabilities sometimes lack the physical capacity or even the motivation to prepare and cook a meal. Young children will often have only two or three types of food that they’ll readily eat, potentially leaving them vulnerable to nutritional deficiencies in other areas.

When protein intake is inadequate the hair becomes fine and thin, and hair breakage, split ends, or hair loss usually results. Research studies have shown that if we go more than four hours without eating, the energy levels to our hair follicles is decreased, and the formation of hair protein cells is affected.
