What is a Hair Drug Test and How it Works
It takes almost 5 to 10 days after the last intake for the drugs to grow above the scalp and into your hair and stay there for up to 90 days. So, any specimens that are collected outside this detection window might not appear in the hair test. To cleanse the hair of any external contamination for example powders or smoke, all specimens are first washed with special shampoos before testing. Then the laboratory uses enzyme-linked immunosorbent assay methodology to detect the presence of any illicit parent drugs or their metabolites. Most Laboratories confirm by doing a second screening of the samples that test positive in the screening by subjecting them to Gas Chromatography, Mass Spectrometry or Liquid Chromatography/Tandem Mass spectrometry confirmation testing.

Questions about the hair follicle testing
Q: What’s the Detection Window for Hair Drug Test?
A: On average, a human head, hair grows approximately half an inch every month and the typical length of a head hair test it is 1/2 inches from the root to the tip. Hair test detects drug use between 5-90 days’ time frame from the specimen collection. However, since every individual has unique hair growth rate, the time frame is only an approximate value and can vary greatly.
Q: What Drugs can a Hair Test Detect?
A: A hair test usually detects these five illicit drugs including marijuana, amphetamines, cocaine, opiates, and phencyclidine. However, some more advanced hair drug tests can also detect abuse of prescription drugs.
Q: Body Hair Vs Head Hair
A: Since body hair’s growth is comparatively slower, they offer a more distant time frame than head hair. Body hair can be used when a person shaves his head or is completely bald. However, since body hair grows at an even more diverse rate than head hair, the approximate time period for body hair is extremely hard to identify.
Q: Is Beating Hair Test Possible?
A: The hair test is growing popular because it is the hardest drug test to beat. Although chemical adulterants, such as shampoos dyes bleaches, are commercially available, the effects of these products are not certain.
Common Issues with Hair Drug Test
One of the major issues with hair drug test is the high possibility of external contaminants that can get stuck in the donor’s hair and can result in a false positive result. However, when washed properly, the specimen can be cleansed of any external contaminants. On top of that, the hair test not only tries to detect the parent drug itself but also metabolites. This is very handy because in some cases, for example in marijuana analysis, the test only checks for metabolites which can be produced by the body and can’t occur as an environmental contaminant.
The police department used hair follicle testing to detect any illicit drug use in officers, but a lawsuit was filed stating that the black officers, being more prone to false positive testing, were being unfairly singled out by these tests. The laboratory that tested the officers found that 55 black and 40 white officers were tested positive for cocaine between 1999 and 2006. Interestingly, the number of white officers tested was 2.5 times greater than that of the black officer tested. At the end of the lawsuit, the court threw out the test results, and 6 out of 10 fired officers were rehired. That means the hair testing industry has to come up with something special to make sure that African-Americans, Asians, and other minorities get a level playing field with their light-haired counterparts.
