The other thing that needs to be taken into consideration is "who" is reading the hair analysis and is treating the patient. It's like finding an experienced homeopath. For me, third time has been a charm. The first two homeopaths did absolutely nothing for me. My experience in the past (5 years ago) with hair mineral analysis was nothing like what Christine was presenting. The doctor that gave me the test only discussed my mineral levels, my toxic metals, and tried to treat for such. Vitamin deficiencies and excess levels were never brought up or treated by that test. So experience and knowledge of the practitioner that is giving the test, I feel, is very important.
