In case of metabolic disorders the flow of nutrients to the hair bulb is disrupted. Hair vitality and proper development depend on normal metabolism, on timely and sufficient numbers of the necessary nutrients. With metabolic disorders hair do not get some of the necessary components, and, instead, might receive substances having an adverse effect on their growth and formation. Overweight and fatty foods stimulate secretion of the scalp skin sebaceous glands and directly affect the condition of the hair.

One of the important conditions for the hair health is proper nutrition. Every day with food we must receive the necessary number of proteins, fats, carbohydrates, vitamins, trace elements and other nutrients necessary for normal development of the whole body to sustain life. Food provides the body with energy, plastic and biologically active substances that are necessary for the regulation of life processes. But the excessive use of some food products is also undesirable, for example, use of the very fatty foods leads to a hyper function of the scalp skin sebaceous glands, which directly affects the hair. Quality food balances processes of proper income and expenditure of the energy. Chemical building materials and biologically active substances of food are needed to create new cells and intercellular structures for the regulation of vital processes. Most hormones and enzymes are synthesized by our body itself, but some of them can be obtained only from the food in form of vitamins and trace elements. For all these reasons food should be complete, reasonable and balanced. Protein is an essential hair enzyme. The cells of our hair are composed of protein, amino acids and melanin. Located in the food (especially fish and cereals), protein in the digestive process is transformed into amino acids and distributed throughout the body. Nutrients of food products required for hair growth for the 10-year-olds absorbed by 90%, 20-year-olds - 75%, 30-year-olds - 50%, 40-year-olds - by 30%. To have your hair healthy and beautiful all the time you need to pay particular attention to the amount of nutrients in the food on daily basis.

Stress, insomnia, neurosis, nervous disorders are fairly common causes of hair loss. Stressful pace of life, increase in the intensity of work with weak physiological activity "produce" a number of diseases associated with a nervous system tension. As a result of the stress the body can not relax and restore the psychological balance. Nervous system tension adversely affects our whole body - the blood, digestion, reduces the level of energy. Stressful lifestyle affects the process of digestion and violation of this process is deteriorating absorption of nutrients and interferes with the growth of hair. Hair roots receive nutrients from the blood and are is a subject to sympatetic nervous system tropism. Every nerve ending, attached to the hair follicles, produces certain substances. Quantity of these substances is in proportion to the nerve center tonicity, from which particular nerve endings originate. Very often hair loss may increase due to a tonicity of nervous centers and the number of these substances being insufficient for normal hair growth and development.

Certain strong medication treatments contribute to hair loss, an excessive use of antibiotics and hormones specifically weakens hair the most.

A gene responsible for a hereditary hair loss is not determined yet, though it has been proved that a common reason for such hair loss is an extraordinary sensitivity of hair follicles at the top of the head to the effects of DHT (dehydrotestosterone) hormone is not typical to everyone, so that suggests on the existence of hereditary factors.

Increased hair loss may occur as a result of the body physiological restructuring. During pregnancy, after birth, during puberty and menopause due to various causes of violations of the hormonal balance in your body hair may begin to thin and fall out. Excessive sportsmanship requires large amounts of calories and especially when the need for these calories is not fulfilled, state of the hair may be affected.

Endocrine system disorders cause hair loss. If there is a lack of thyroid hormones, the body senses a shortage of protein, hair growth may start to deteriorate and alopecia may develop. Disruption of the liver, kidneys, adrenal glands contributes to inflammatory processes and leads to the accumulation of toxic substances. For example, disruption of the gallbladder function results in its inflammation and leads to the front right side of the head hair more intense fall out and greyness in comparison to the left side.

Gastrointestinal disorders, constipation often provoke hair loss (symptoms: allergies, bad breath, diarrhoea, vomiting, etc.). With normal activity of the stomach and intestines our body regularly removes unwanted substances that come with food. If any function of the intestines deviates this provokes unwanted accumulation of these substances and constipation, which means that unwanted body substances constantly accumulate and poison our body.

With any blood circulation disorders (symptoms: inconstant heart rhythm, frequently or constantly cold toes and hands, etc.) hair nutrition is failing, hair tend to thin and fall out.

With lung diseases (symptoms: heavy breathing, lack of air, bronchial cough, a cough from the lungs, weak voice) hair begin to thin especially on top of the head. Any form of improper breathing also reduces the required amount of oxygen in the body and affects the state of hair.

Rheumatism, arthritis, bone diseases, pain in the feet and hand joints and their weakness encourage hair thinning. Neck osteochondrosis has a great impact on hair loss due to a violation of nerve fibre tropics in the spinal column.

Unhealthy lifestyles, overdoses of alcohol, smoking, constant physical and mental stress, improper posture, lack of physical activity, etc. stimulate additional stress on the blood circulation system, significantly weakens the growth and condition of hair.
