Hair analysis uses samples of hair for
DNA analysis or to look for heavy metals, such as lead or arsenic.
Heavy metal analysis
The results of hair analysis are usually complete within 3 weeks.
You or your health professional will receive a report listing the levels of
minerals and heavy metals in your hair. Several factors need to be considered
before testing for heavy metal exposure.
There is no standard procedure for cutting, washing, and
analyzing hair. Different labs may report different results from the same hair
sample. In fact, the same lab may report different results for separate hairs
from a common sample. Standards for testing do not exist. Any hair analysis to
detect the presence or absence of minerals, nutrients, or toxic metals in the
body should be confirmed by testing blood and urine samples.
What the hair sample contains is determined not only by nutrition
and internal metabolism but also by external substances. Air pollution, mineral
content of the water supply, exposure to industrial waste, shampoos, hair dyes,
hair sprays, permanents, and bleaches may raise or lower the levels of certain
minerals in the hair. In addition, the use of medications such as birth control
pills can change the mineral concentration of hair.
