In drug test samples like urine, hair, blood, sweat, or oral fluid are technically examined to determine the presence or absence of specified drugs or their metabolized traces in a person. Due to this benefit Hair Drug Tests have become one of the most trusted methods of drug detection today and is used by law enforcement officials, organizations and parents alike. There are various types of drug tests available on the market. Hair drug test is a simple procedure that involves removing a strand of hair from your head or the participant’s head. This strand is then sent away to a lab for analysis.

A hair drug test is a quick and easy way to test because hair drug testing can detect drug use up to six months, habitual and occasional drug users are reluctant to take this test. The drugs, which have been used, are encased in the hair shaft, which becomes permanent. The only way to not detect drug use is to cut or shave the hair. Of course, if you were to shave your head prior to a hair drug tests, this may appear a little suspicious. Whereas other common test like blood and urine test can only detect drug use that took place within the last three days. Thus, it is possible for a drug user to quit using illegal drugs for a short period in order to pass a drug test, thus making these tests more inaccurate. Hair can be collected from several head and/or body locations (excluding pubic areas) and combined to obtain the required amount of hair. In the rare case where no hair is collectable, complete urine/adulteration testing may be utilized. A standard hair follicle screen covers a period of approximately 90 days, but is susceptible to time variation depending on the growth rate of your hair. The hair sample is cut as close to the scalp as possible and the most recent 3.9cm (or 1.5 inches) are tested. It is possible to go back even further than 90 days since the time period is limited only by the length of the hair sample, but is standardized to a 90-day history.

A hair drug test detects five major drugs namely marijuana, cocaine, amphetamines, opiates, and PCP. Failing a drug test may have serious consequences. The employer or agencies that administer the tests have different procedures. When someone is unable to pass the hair drug test will likely to be denied coverage with an insurance agency, employees who fail a random hair drug test may be allotted a certain amount of time to discontinue drug use.
