The hair drug test can detect drugs going back approximately 7 to 90 days; this drug test is also difficult to cheat, adulterate or substitute. There are many ways to detect drug use, but urine and blood samples can be more difficult to get than a hair sample. Hair analysis also has the longest window of detection of any testing method, although it can’t detect all the same drugs as other tests. If you’re wondering how hair tests work, here’s what you need to know. The accuracy of any hair drug analysis depends on both the sampling procedure and the laboratory techniques employed. An accredited drug testing company ensures that the samples are analyzed using state-of-the-art equipment to quickly identify specific illegal drugs, even those that are new to the market.
Understanding your results
They’ll use confidential means, like a secure fax, a phone call, or an online interface to share test results. When it comes to figuring out how to pass a drug test, everyone seems to have a secret home remedy that they swear by. However, testing technology has drastically improved throughout the years.
How to pass a hair follicle drug test with detox shampoo
Beyond the ethical implications of drug use in a professional setting, there are, of course, legal considerations. One challenge we see with hair drug testing is the training of hair drug specimen collectors. Many times specimens received at the labs are rejected for an insufficient quantity of specimen. We also see different labs quoting different quantities of hair required for hair drug testing so standardization will be very important.
Does body hair hold drug residue longer than head hair?
If your hair sample collection is not witnessed then there are several options open to you. You could send in another person’s ‘clean’ hair sample; you could take a section of hair from another area other than that requested; and you could even submit fake or even animal hair. For drugs to show up during testing, they need to enter a blood vessel that supports your hair cells’ growth. When you inhale secondhand smoke, only trace amounts of THC are entering into your body, and they’re unlikely to make a non-user test positive.
Multiple illegal substances, as well as some legal medications, can be detected. The test can reveal long-term drug usage even if the individual has stopped using a few days before the test since THC and cannabis remain in the hair follicles for a long time. Hair drug testing has a much longer detection window than urine drug testing plus it is significantly more difficult to cheat on hair drug testing. Hair tests analyze the drugs inside the hair shaft on which external contaminants and chemicals have no effect. Standard hair testing has about a 90 day look back period to detect drugs at about 7 days after ingestion.
Panel Hair Test with Expanded Opiates
This test analyzes a small sample of hair from close to the scalp to determine drug use within a 90-day timeframe. Hair samples that produce a positive result for ELISA testing will undergo a second test, such as GC-MS. A positive result with confirmatory testing means that the laboratory confirmed the presence of specific drug metabolites in the person’s hair sample. Exposure to secondhand smoke, like weed smoke, is unlikely to lead to a positive result in hair follicle drug tests. The tests are designed to detect metabolites that are absorbed internally, not through external contact.
Treatment Process
When collected close to the scalp, hair can provide up to approximately a 3-month detection window for alcohol and other drugs. Hair is simple to collect, somewhat difficult to adulterate, and easy to ship. We're here to help you understand how long drugs stay in your system and how urine, hair follicle, and saliva drug tests work. Plus, we'll give you the best strategies for passing a drug test and tell you what to avoid and which products aren't worth your time or money. The best way to pass a hair follicle drug test is not to have any traces of drugs or chemicals in your system. On the other hand, you can use detox home remedies, detox shampoos, such as Zydot Ultra Clean Shampoo and Aloe Toxin Rid Shampoo, the Macujo method, and follow the dos and don’ts list.
When someone uses drugs, the chemicals in those medicines end up in their bloodstream. The length of the sample must be one and a half inches, and it must have a thickness comparable to that of a pencil. In contrast, urine and blood tests provide a look into an individual’s most recent drug use. They can be ideal in environments where the focus is more immediate substance use rather than historical patterns.
What Drugs of Abuse Do Hair Tests Show?
Metabolites remain detectable in a hair sample for up to 90 days from when they were consumed, and it can be an even longer period for certain drugs. Even in trucking companies where DOT required the standard 5 panel urine test; an additional hair test is required by many trucking companies. Another myth is that shaving your head or body hair will lead to a negative result in a hair follicle drug test. Hair follicle tests can still be conducted with body hair or shorter hair samples. Shaving does not eliminate the presence of drug metabolites in the body.
Accredited Drug Testing Inc. is pleased to provide hair follicle drug testing, alcohol testing, occupational health and DNA testing services in , . Generally a negative hair follicle drug test result is available in 2-3 days. A non-negative hair follicle drug test is available in approximately 5 days. When the hair sample is taken from slower-growing body hair (such as from the armpit) instead of the scalp, the detection window widens to up to one year. Most hair drug tests can detect heavy or regular use of certain illicit substances over the past three months. Hair drug testing goes back much, much longer than urine drug testing.

In a hair follicle drug test, a sample of hair is analyzed for drug traces, offering a detection window of up to 90 days, depending on hair length. These tests provide a comprehensive history of drug use and are tamper-resistant due to strict collection supervision. Many at-home tests will charge an extra fee for the laboratory analysis, adding to the total cost of the test.
Some detoxification shampoos are designed specifically to permanently reduce toxin levels in the hair strand so they fall below detectable levels in a laboratory hair test. By penetrating deeply into the hair strand these shampoos claim to remove all traces of accumulated chemical deposits including drug metabolites. If you’ve been in an environment heavily laden with a drug, detectable levels could be found in your hair sample due to smoke. In addition, it could be transferred by direct contamination (such as by hands).
An inconclusive result isn’t common when testing procedures are followed. In some cases, improper collection of the hair specimen may result in the test being rejected completely. If you have very little or no hair on your head, the collector might use body hair for the test instead. The collector will place the hair in foil and then in a secure envelope to be mailed for overnight testing.
The collector secures the hair sample in foil and completes chain of custody documentation in preparation for shipment to the testing laboratory. Even though these tests are commonly referred to as “hair follicle tests,” hair follicles are not used in the test and hair does not need to be plucked to be tested. Instead, a sample of strands of hair are cut or shaved and those strands are tested.
