What is Hair Drug testing?
Hair testing is the most accurate and effective method of finding users of drugs of abuse. Using a small sample of hair cut at the scalp, hair analysis evaluates the amount of drug metabolites embedded inside the hair shaft. Analysis of hair provides a much longer “testing window,” giving a more complete drug-use history going back as far as 90 days. Hair testing does not provide evidence of current impairment, but rather only past use of a specific drug.

Can Hair testing be beaten?
The test provider has not found any adulterants that can beat the test at this time. Moreover, the risk is minimized because every collection is directly and easily observed. Bleaches, shampoos and external contaminants (i.e. marijuana smoke) have no known impact on test results. The testing method measures the drug molecules embedded inside the hair shaft, eliminating external contamination as a source of a positive test result. Hair testing results cannot be altered with shampoos or other external chemicals.
