Many amateur and professional athletes are also required to have drug tests, as taking certain kinds of drugs can give you them an unfair competitive advantage and adversely affect their health. Nowadays, parents are even requiring their children to undergo hair drug testing if they are worried that they may be taking illegal drugs.

Out of all the available methods, a hair follicle drug test is one of the easiest types of drug testing. The only requirement is that a person submits a simple sample of their hair, which is very easy to do. First, a hair sample is collected and then sent in a sealed envelope to a laboratory where it will be tested.

Hair drug testing is also advantageous because it is able to detect any type of drug use within the past 90 days. That means that if an individual has used drugs 3 months ago, the test will still show a positive result. This is quite different from other types of drug tests such as saliva and urine tests, which only detect drug use for as little as a few days. The reason that drugs can be tested for a much longer time frame is that small amounts of chemicals from the drugs are trapped within each strand of hair.

Hair drug testing is also one of the most accurate and fastest of any type of drug test. A hair follicle drug test is often chosen because its accuracy rate is usually ten times higher than other existing drug testing methods. This makes it a preferred choice for many individuals, companies and coaches who want to ensure that the results they receive are completely accurate.

Yet another advantage of hair testing is the fact that it is completely confidential. Individuals do not have to submit embarrassing urine or saliva in order to be tested. All that is required is several hair strands to produce very accurate results.
