Hair Analysis 

Hair analysis is among the most cost-effective mineral analyses. Hair is less susceptible to erratic changes in the blood that affect trace element levels. It provides a long-term record of mineral excesses and deficiencies, as well as an accurate long-term record of biological activity (your metabolism). Also, hair is E.P.A. recognized for the assessment of toxic metals. Collecting a hair sample (at home) is quick, easy, and non-invasive.
