Hair drug tests are becoming the preferred drug testing for employers and court-ordered testing. Testing hair can determine if a person has ingested drugs in the past 90 days.

Since hair tests can identify drug use further back in a person’s recent past than a urine test, many employers are now opting for a hair drug testing, particularly for pre-employment screening.

Hair testing is also becoming more common in the legal industry when court-ordered drug testing may be required, like for probation, or divorce and child custody cases that may have mandatory drug testing.

Urine drug tests can only identify drug use for approximately a week into an individual’s recent past. For that reason, hair drug or hair alcohol EtG tests are better suited to detect binge or chronic drug usage over a more extended period of time.

National Drug Screening offers hair follicle drug and alcohol screening for employers and individuals throughout all areas of the United States.

Effective Hair Testing For Drugs And Alcohol

Although it is still fairly new technology, hair testing is very effective as long as it is administered by a properly trained technician. National Drug Screening is a national leader in hair drug testing. Our experience has allowed us to develop the expertise that has helped to make our testing processes as simple and efficient as possible.

All of our tests are analyzed by certified labs like LabCorp or Quest Diagnostics. National Drug Screening hair follicle tests are also always reviewed by a certified MRO (Medical Review Officer) before the results are released. If an initial screening yields non-negative results, then they will undergo additional Gas Chromatography-Mass Spectrometry (GC-MS) confirmation testing. This allows individuals that may be legitimately taking prescription medication a chance to provide authorized proof to our doctors. 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”.

We Don't Actually Test The Hair Follicle's Root

While the test is called a hair follicle test, it is not actually the root itself that is tested. Hair drug testing uses the first inch and a half of growth from the base and roughly 120 strands, to determine any drug use within the past 5 to 90 days.

When a person ingests a drug, it enters into the bloodstream while the body simultaneously metabolizes the drug, causing those metabolites to circulate through the blood as well. Since a person’s blood nourishes their hair follicles, any ingested drugs and their metabolites are deposited into their hair follicle where the evidence of drug use remains indefinitely, or until the hair is shaved, once the hair grows out of the follicle.

Can Body Hair Be Tested For Drugs or Alcohol?

If the head hair is not long enough or shaved, then a sample of body hair from the legs, chest or armpits, and occasionally beards, can be used instead. Many people may think that body hair grows slower than head hair, which is why using an inch and a half of body hair for a hair follicle test will provide a longer period of drug use than an inch and a half of head hair.

However, body hair and head hair generally grow at the same pace, but body hair usually stops growing at a shorter length. Once the hair stops growing and becomes dormant, it is pushed out to make room for a new hair to replace it, which is why we appear to shed at times. A positive drug test result doesn’t actually indicate the exact date or dates the drug was used, just that it was ingested in an estimated timeframe within the last 90 days.

Can You Cheat a Hair Drug Test?

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.

There is also some concern regarding environmental exposure to drugs, such as second hand marijuana smoke, and how it can affect a hair follicle test. National Drug Screening’s hair follicle tests screen for not just the drug itself, but also the metabolites your body would produce if you ingested, or smoked, the drug. That means that even if marijuana smoke got stuck in your hair, as long as you did not inhale it, then your hair will have no evidence of marijuana metabolites, so your test will not be positive.
