why you WANT to see heavy metals in your Hair Analysis
Toxic elements may be 200 to 300 times more highly concentrated in hair than in blood or urine.
Therefore, hair is the tissue of choice for detection of recent exposure to elements such as arsenic, aluminum, cadmium, lead, antimony and mercury.

Rather than seeing elevated mercury in the hair, a person who doesn't excrete mercury will actually have extremely low levels in the hair, because they are holding onto it rather than metabolizing…excreting it.

If you get a dental revision and have the mercury removed from your mouth, the holistic dentist will do (among other things) a heavy metal hair analysis to see if you are a "dumper". If heavy metals are present in the hair, it means you are effectively metabolizing (DUMPING) AND IF NOT THEY WILL NOT PROCEED WITH MERCURY REMOVAL UNTIL YOU START A METAL DETOX FIRST.
God gave us everything we need. If only medicine recognized THAT.
