Hair drug test provides accurate results of drug contents in a body. The more hair an individual has, the easier it is to detect the presence of drugs in the laboratory. Lab technicians use hair that is about 2.5 to 4 cm to test for presence of drugs. Each 1.27 cm hair gives information of drugs consumed 30 days before. Some people feel they may clear the test by shaving the head. In case, hair is missing on the head, hair from other parts of the body may be used as a substitute.
Absence of hair sometimes becomes a reason for not hiring an individual in some jobs. Law enforcing agencies and major companies make use of hair drug test before hiring employees. Based on the efficiency and accuracy of this test, employers hire new people. Hair drug test uses radioimmunoassay technology and spectrometry for accurate results.
Hair drug test is a convenient and modern technique and is widely used to detect drugs before in companies and educational institutions. Hair drug testing kits are user friendly, and have instructions on collecting the specimen and sending to the laboratory for examination.
When an individual consumes drug with another substances such as drinks, food or medicines, it mixes with blood. Blood transports drug through all parts of the body, which includes the head also. The chemicals spread to hair follicles. Therefore, these chemicals become a part of hair.
To pass a hair drug test is very difficult. There are rumors that dying or bleaching hair helps to pass the test. However, this does not work. Next, shaving the hair off the head also does not work. The laboratory technician will use the hair from other body parts.
You may not be able to get through the test or clear the test, if you shave the hair from your entire body, because the new hair, which grows from your body, will be as effective in detecting the drugs in the body as the old hair.
Once the drug has entered the body, and you are going for a hair drug test, there is absolutely no way to beat the test. Despite the presence of various products in the market to beat a hair drug test, the results are usually ineffective.
In short, it is impossible to get away with a hair drug test with the help of shampoos or a shaven head. The only way to pass a hair drug test is to stay away from drugs.
