If you look at her analysis here related to Sodium/Potassium levels in the hair, and her explanation of Copper related to hair analysis/nutrition you will see some distinct similarities. I stated that her work seems to be based on the work of Dr Lawrence Wilson, that doesn't mean she adheres to his theories -- but the explanations of mineral ratios, deficits etc have to come from somewhere -- they seem to be rooted in the work of Dr Lawrence. Some of Dog Person's comments regarding why we do things -- ask question, argue etc were stated as being the result of nutritional deficiency and poor balancing -- you can find these statements here and in the work of Dr Wilson. I did a search and I found some interesting similarities, I couldn't any other researcher who is so similar in the work. All theory comes from somewhere. Dr Wilson seems to have been very pioneering in the work he has done in Hair Mineral Analysis, he might be the leader in this kind of work. All research stems in some degree from other research. It's the nature of science. I am hoping that Dog Person will point out to me why her statements regarding copper, Na/K, the relationship of mood/personality to nutritional deficiency is different from Dr Wilson's. Then I will say I was totally wrong. I am hoping she can point us to the research she uses to dispell my assumptions. I was trying to be helpful.
