"Unfortunately if you are in the US you need approval to get a hair test from either a doctor, naturopath, chiropracter etc. But it is something well worth considering in my opinion."
TK--- This is not quite accurite. Hair analysis can be done privately in the US through Direct Lab services who uses Doctors Data [which is the most useful] for the testing. You can also order many other medical tests through DLS without a doctor or practitioner.
