Sampling Location:
Head hair taken from the nape of the neck, (
click
here for illustration), will provide the best sample.
The growth of the hair here is relatively steady and should
give good, consistent results.
As an option, axillary hair, pubic hair, or other body
hair may be used. The growth pattern here varies and is
rather sporadic but it produces adequate results. Note,
however, that samples from the head and different parts
of the body should not be mixed together.
Sampling axillary or pubic hair is also a very good way
to confirm that elevated toxic minerals which have been
found in the head hair are also present in the whole system.
