Hair is a part of the whole human body, and if we have a serious problem with our hair, it means we have a problem with the body’s overall health status. Sometimes we are incomprehensible to basic things, or understand them incorrectly. It seems clear to everybody what a meaning of health is, but, actually we are starting to realize this only when we are faced with some illness or disease. So what do we mean by health, what is it? Health - this word is always singular, because the health is only one for anyone, it is a present status, the most important component of quality of our life. Health - a volatile property and state of the body, our health needs an active and intelligent support when necessary, it is always our personal, rather than someone else's matter. Health is a harmony of soul, mind and body. Each one of us has a certain level of health reserves however you need to know how to use those. Our body has fantastic abilities to compensate weak spots in health, as it is a very complicated system in a first place, that has constantly to adapt to constantly changing outside environment. Any deviation of such a balance of conditions of life immediately triggers a chain of processes, which are targeted to optimaly compensate for this deviation to bring our system back to such a balance. In order for the body to react to any deviation from normal health, the body shall have an ability to respond in a first place. If this ability for some reason is weak, the return of general health becomes problematic. Quite often serious hair problems are first signs of body’s general health condition deviation from the normal. In order to properly understand all this in terms of hair loss and associated problems  you need to get a general understanding of your hair and skin biology. As the hair and skin formation and development depend on blood composition and it's circulation, hair has a lot information about their owner. Blood composition and circulation shows food quality and diet (or its lack), daily fluid volume and it's type, drugs, quality of sleep and rest, breathing and a lot of other things. Summary we can assume, that our hair as a result of our blood composition and circulation reflect our state of health. The hair keep secrets of our lives even after death. For example, laboratory studies have shown that the Egyptian Pharaoh Ramses II, who lived in the XIII century BC, had a copper-colored hair achieved by means of dying those in henna. Melanin in the hair acts as a sponge, absorbing and retaining all the chemical information. Since melanin is so sensitive to various toxic substances, it provides a great service to the practical, legal and forensic medicine. For example thanks to performed hair research laboratory studies proved that Napoleon Bonaparte was murdered by arsenic.
