With the rising incidents of cheating the home drug tests, hair drug testing has gained immense importance and populairty.
Hair drug test is not only hundred percent reliable but it is also easier to collect the samples. The strands of hairs can be collected from the pillows or towel without any knowledge of the person who is suspected of being addicted to drugs. The logic behind using the hair as the sample for drug testing must be understood. Blood is a medium that carries everything from oxygen to food to all the parts of a human body, including hair. So if a person is addicted to drug, it is also be transported by blood and forms a layer at the hair. So hair drug testing can be an effective method of identifying the case of drug abuse.

Such feature is not found in the case of urine or saliva drug testing. So, this is obviously a unique feature of detecting the case of drug abuse.
Hair drug testing can not identify the use of all drugs. Still it can detect the use of some of the most commonly used drugs such as cocaine, amphetamines, methamphetamines, codeine, morphins, marijuana etc. But in case of marijuana, the frequency of use can not be detected with accuracy due to the nature of binding of the drug to the hair. Hair drug testing is no doubt an efficient and quick method of testing drugs but it is expensive as compared to the other types of drug tests. Any advnaced test does not come easy on one's wallet. For example, DNA paternity test is the most popular testing of proving the biological relationship between an alleged father and a child but the test is very costly.
