Using modern biological, physiological, and biochemical concepts, Dr. Paul C. Eck uses hair analysis kits to change people's lives.  He can evaluate stages of stress, sympathetic and parasympathetic balancing, oxidation, mineral balancing, and many other things.  Utilizing these concepts and discoveries, he can understand the significance of tissue mineral levels, as well as rations and metabolic patterns.  Through these studies, he can identify trace mineral deficiencies and excesses and correlate his findings to their relationships with various metabolic dysfunctions associated with specific diseases.  With these discoveries, he can help people enhance their lifestyles through proper coaching and appropriate nutritional balancing.
