Hair Follicle Drug Test — Everything You Should Know

Hair Follicle Drug Testing

What is a Hair Drug Test and How it Works

A hair test is administered to detect parent drugs as well as their metabolites in the hair specimen collected from a donor’s body or head and can offer an extended, 90-day lookback. The collected specimens are sent to a sophisticated laboratory that screens the hair for any illicit substances and the results are usually available within 1 to 5 business days.

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.

#2:  Test Country’s 365-Day Hair Drug Testing Package for Parents

hair-confirm-1$229

This highly accurate hair drug test by Test Country is specially designed for parents who worry their kids are taking illicit drugs. The package costs $229 and contains four drug testing kits so that you can test your child every 90 days. While the investment might seem like a big one, but it boils down to $19 per month.

The good thing about this test is once you buy it, you will be able to test your kids for a whole year. However, if you have more than one kid, this test can get expensive. While Test Country claims that external contaminants such as shampoos, bleaches, and other chemical contaminants sold commercially can’t alter the results, scientific researches prove otherwise. And in case your child knows that you will be testing them for drugs, and they suddenly start using bleach or any other chemical on their hair this could be a red flag. Also, the test can be performed on body hair in case your child doesn’t have hair on their head or has very short hair.

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.

Another probably even bigger issue with hair is racial bias. Apparently, light colored hair is less susceptible yielding a positive result while dark hair is not only more prone to attracting contaminants but also have a higher chance of false positive. Although many big laboratories try to dismiss this claim for personal gains, however, a popular lawsuit in Boston shows us the irony of a hair test.

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.

Common Tricks to Beat Hair Drug Test

There are several things that people can do to beat the drug test.

  • Shaving off your head as well as the rest of your body
  • There are several detox shampoos available that claim to help people pass a hair drug test, however, their authenticity is questionable
  • Since the drugs can be tested for as long as 90 days after the use, many people stop using drugs when they’re expecting a test

A lot of people claim to have passed a hair drug test by using commercial products. Most of these products are expensive, and may or may not produce the desired results.

  • The CPS said my 18 month old was on meth. No one has do e meth around her. Now I tho k it was a lie so they had a respond to place her in CPS. They are leaches waiting for an excuse. The government should stop them. I know how they can lie and cheat people but dont know how to fight them.

    • My daughter had a hair strand test while she was in a residential unit with her baby and she had to go to court for a review. The test came back positive for cocaine the unit terminated the assesment and the baby was put back in foster care. My daughter swears she hasn’t taken cocaine and the judge agreed for another hair strand test which will be revealed on Friday. The judge will decide for another assesment depending on the results from the hair strand test if it’s posative then she’s facing adoption. My daughters other weekly drug tests have showed negative on all dates. The courts and all have really run my daughter into the ground.

  • CPS of Grady county Ga came in and took my newborn daughter because she was supposedly born with the drug in her system. Funny thing is I never gave consent for her to be tested for any reason. They took her stating that because I would not comply with the demands of CPS they were removing her from my custody. I have no preexisting case of meth use or with CPS at all. Yet I had my daughter taken without even 12 hours notice. I’m still without her she is a month old now. I have no doubt that even if I pass the hair test I won’t because they will not be proven wrong.

    • Yes, I am wondering the same thing also. Does tramadol show up on a 5 panel drug screen for a urine drug screen? Will it show up on a hair follicle?

      • Tramadol does NOT show up on a DOT 5 panel urinalysis, well at least it does not create a fail, I’ve never seen the complete drug test analysis. I’ve taken several DOT randoms with no problem. Hair follicle tests are a different story. Tramadol does show up on them, so you better have a prescription (which will disqualify you from CDL driving jobs)

  • I stopped smoking about 2 and a half months ago cut my hair 3 times. Will I pass my hair test next week?

    In your hair for testing
