Unexpectedly outbreaking strong hair loss may be due to lack or excess of vitamins and minerals. It has been scientifically proved that there is a direct relationship between the hair composition and condition and a shortage or an excess of certain vitamins and macro-and micronutrients. In addition, every day we feel the impact of many factors and the need for vitamins and minerals due to the quality of our food for a certain overall number of proteins, fats, carbohydrates, minerals and vitamins. Climate has a direct impact on the absorption of most vitamins and minerals as when it is hot more vitamins and minerals are being removed from the body, especially feels the shortage of vitamins A, B1, B12 and C. The need in certain minerals and vitamins, especially B1, B2, B6, PP and C is being increased by physical exercise, infectious diseases, changes in the physical state of the female body in the time of pregnancy, lactation, etc., under the influence of aging for seniors. Located in the human body minerals account for only 4-5% of the total body weight, out of which about 50% takes up calcium, 25% - phosphorus, the remaining 25% are other macronutrients, such as magnesium, natrium, chlorine, potassium and sulfur; and trace elements, such as iron, zinc, iodine, manganese, fluoride, molybdenum, cobalt, selenium, chromium, tin, nickel, vanadium and silicon. Total body macronutrients account for slightly more than 5 grams and trace elements for less than 5 grams. They serve in the body a dual function: construction (for example, calcium in bone tissue, etc.) and control (for example, iodine, which is a part of the thyroid gland hormones, calcium and magnesium serve for regulatory reduction and relaxation of muscles, etc.). With sudden changes in the hair state, first of all we want to make sure our body gets enough vitamins, macronutrients and trace elements, and seek to balance their intake with our daily ration. Most people can hardly notice any signs of shortage of vitamins and minerals, and especially establish which ones exactly are missing. Sometimes quite relevant and important might be to know what are specific signs of the lack of one or other nutrient in the body, as it will be easier then to change and normalize the situation in our entire body, including the condition of our hair.
