The human body is not capable of metabolizing and processing large quantities of toxins, and as a result, allows toxins to accumulate. This can have both subtle and powerful effects on your well being. As toxins build up, they can damage cells and displace key nutrients your body needs to function properly. Scientists are finding more and more that the amount of toxins necessary to affect behavior and the central nervous system is much lower than previously believed. With repeated exposure, toxins may eventually accumulate inside organ tissue, such as those of the liver and kidney.
Toxins can also increase production of free radicals.
Because hair actually retains the toxic elements trapped in your body, hair screening can provide an accurate and powerful means of evaluating the effects of cumulative, long-term exposure to toxins. A growing hair follicle first begins forming far below the skin, exposing it to a rich supply of blood vessels. As the follicle grows, toxic elements in the blood are absorbed into the growing hair protein. When hair reaches the skin surface, it undergoes a hardening process called keratinization - where toxins accumulated during hair formation become sealed into the protein structure of the hair. By this process, toxic concentrations of hair will reflect toxic concentrations in other body tissues.
