Has anyone here had good results from having a hair analysis done? We are seeing a doctor Monday (for our son) who does the analysis (in addition to blood work) to test for food allergies. He feels a lot of the symptoms of CFIDS can be alleviated through avoidance of certain foods. We've already found out to avoid Nutrasweet, MSG, nitrites, and wheat, but we're willing to try whatever it takes to get him better. He obviously has MCS (multiple chemical sensitivity) but maybe we can get him back to his old energetic self. He is 18 and starting college in the fall (he'll be able to live at home.)Any thoughts?
