Everything You Need To Know About A Hair Follicle Drug Test
A hair follicle drug test is one of the newer types of drug testing available and is quickly becoming the preferred drug testing for employers, as well as court-ordered probation testing. Hair testing allows for detection of substances like marijuana, cocaine, obiates, barbiturates and many other types of drugs. Hair drug testing 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. It 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 provides 5-panel, 7-panel, 9-panel, 12-panel, 14-panel and 17-panel hair follicle testing. All of our drug tests can be purchased online, or by calling us at 866-843-4545 to schedule a test at a location near you.
Types of Hair Drug Test Panels
There are several types of hair drug test panels available, depending on the substances you want to test for. The most common tests ordered are 5-panel and 12-panel tests; however, you can find comprehensive testing for any and all combination of drug and alcohol use.

Negative results for a basic 5-panel hair follicle drug test are usually available within 2 to 3 days. The more complex 9- and 12-panel tests may take a couple days longer; positive initial test results are sent for further confirmatory GC-MS testing which may take a few extra days as well.
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.
