Considering your situation, some individuals explore specialized shampoos such as Old Style Aloe Toxin Rid or Zudot Ulrta Clean to enhance their chances of passing the test. If the hair sample tests positive during this screening, a second test is performed. This test, which uses advanced techniques like gas or liquid chromatography and mass spectrometry, provides a more detailed analysis. This analysis can confirm the presence of drugs and also identify specific substances. A hair follicle drug test, also known as a hair drug test, is a technique used to detect the presence of specific drugs in an individual’s system. This test analyzes a small sample of hair from close to the scalp to determine drug use within a 90-day timeframe.
Hair follicle drug tests
Different labs do the tests differently, and their results can vary a lot. Experts say hair analysis is most helpful when paired with tests that use something other than hair. Yes, sometimes, but it heavily depends on the potency of the drug and the history of use. If the amount of substance stored in your hair is too small to trigger cutoff value, then it won’t show up on the drug test result.
Frequently asked questions
Hair follicle tests are accurate enough to satisfy private employers, but many factors can interfere with the result of a test. It can only show whether a substance has been used within the past 90 days. Cold remedies, decongestants, and hay fever medicines can show up as amphetamines and poppy seeds may show up as opiates. People who shave their entire bodies may not be able to provide a usable sample of hair. Employers who wish to drug test their employees must cover all the costs of taking the test, taking into account the person’s time. Because lab results are confidential health information, you’ll need to sign a release before the results are passed on to your workplace.
Interpreting test results
Often called hair follicle drug test, the hair follicle is not actually tested. The metabolites of the drugs go into the hair follicle and then into the hair strands. The hair strands are cut as close to the scalp as possible for drug testing. Hair follicle drug tests are much more difficult to cheat than urine drug tests since a sample taken is done so directly by a trained collector. Obviously, if someone has no body or head hair, then the hair follicle test cannot be performed. With the urine drug test, the applicant or employee might refrain from drug use for five or more days and avoid the detection of illegal drugs in the urine.
How Does Hair Follicle Drug Testing Work?
As long as the individual takes the medication in accordance with the prescribed dosage, then the final report will list the result as a “negative”. The new 17-panel hair drug test is the most comprehensive drug test panel available in the United State. The cost of a hair follicle drug test can vary, depending on the kind of hair follicle test ordered (the number of drugs in a screen can differ), where you go for testing, and who ordered the test.
Health Alerts from Harvard Medical School
The cost of hair follicle drug testing depends on where a sample is collected, the type of hair follicle drug test ordered, and who is paying for testing. Patient costs may be covered by an individual’s health insurance or the organization requiring a drug test. In other cases, patients may choose to pay out-of-pocket for laboratory-based or at-home collection kits.
The use of drug tests is impacted by federal, state, and local laws. Professional organizations advocate for the ethical use of drug testing, often emphasizing the importance of patient education and consent before conducting a drug test. Once the hair sample is collected, it is sent to one of our many certified labs for professional analysis, and review from a certified Medical Review Officer (MRO).
When should I get a hair follicle drug test?
If you believe your hair drug test results are inaccurate, you may immediately request a retest from your employer. Your hair strand test might take place in a lab or within a hospital setting. Or your workplace may perform the test using a kit that’s then mailed to a laboratory. "I think it’s important to choose well-made and trustworthy devices both for safety and reassurance of efficacy," says Dr. Nazarian. A 2021 review of 15 studies — including several large randomized control trials that are the gold standard for medical research — found that laser therapy increased hair count in both men and women.
Macujo method for drug test
A research by Forensic Science International found in 2004 that traces of opiates drugs were still present in English poet John Keats’ hairs 167 years after his death. If you bleach your hair too many times, it’ll start falling apart, and the lab won’t be able to test it, as stated in the Drug Testing and Analysis journal. The time depends on several factors including the facility’s processing time, workload, test type, and drug type.

Hair follicle tests have a detection window extending up to 90 days, a duration considerably longer than most other testing methods. The lengthy detection window of a hair drug test is attributed to the nature of hair growth and how drugs are incorporated into strands of hair. A pre-employment hair follicle test can contribute additional data to the background check process. Because hair drug testing has a broad detection range, it can provide a more detailed snapshot of a candidate’s substance use patterns than other drug tests. Hair follicle drug tests are performed on a sample of hair, usually collected from a person’s scalp. Once collected, hair samples are sent to a laboratory for testing.
Industries like transportation, construction, and other safety-sensitive lines of work may be most likely to find this type of test valuable for making informed hiring decisions. Usually, they are cut as close to the scalp (and, subsequently, the follicle) as possible, because the portion closest to the scalp is the youngest. Since hair samples are obtained in full view of the collector, the process minimizes the likelihood of sample adulteration or specimen substitution. We offer hair specimen collections in many of our specimen collection sites located throughout the U.S. Our extensive network offers your employees convenient access to a Labcorp collection site. Your hair grows at a rate of about one-half inch per month from the scalp.
One of the most sophisticated types of drug test is hair drug testing, which is also known as hair strand testing or hair follicle testing. The idea behind soaking one’s hair follicles in methanol (Heet) is that labs performing drug tests use the same method to wash out environmental contaminants from the sample. However, methanol doesn’t remove drug toxins from the root and inside part of a long-time user’s hair, as was proven by Zurich Institute of Forensic Medicine.
It’s been discovered that metabolites that are deposited in hair follicles have a much longer lifespan. 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. After drug use, substances enter the bloodstream and circulate throughout the body. As hair grows, it absorbs blood carrying these substances, and the drug metabolites become trapped in the structure of the hair strand. Given the average rate of hair growth (about half an inch per month), a 1 ½ inch hair sample can provide a 3-month history of drug use.
