Hair drug testing is now an acceptable form of evidence in the courts of law in the United Kingdom and the United States of America. It is a more effect testing of drug use over a longer period of time. Hair drug testing is one of the best ways to test for miss-use of drugs in people of highly critical positions of authority where there is a zero tolerance policy of miss-use of illegal drugs. The time covered for a standard hair follicle to still have traces of drugs is 30-60 days which compared to other drug testing methods is significantly longer.
Hair drug testing can also be used on body hair not just on hair from the head. So even if a person has a shaved head or is completely bald hair from any part of the body can be tested including body hair, underarm hair or even pubic hair. Hair follicle testing is becoming increasingly popular as it is less invasive than any other type of drug testing. Scientists now believe that because body hair grows at different than head hair, if the body is tested it can detect miss-use of drugs for up to 12 months.
A hair drug testing can evaluate the number of metabolites in the hair shaft. Every inch in length of head hair can detect a drug miss-use history of the past 30 days and the only time limitation for hair drug testing is the length of the donor’s hair. The length usually taken for a sample will be approximately 1.5 inches in length this will give an approximate history of drug abuse over the last 90 days.
People using hair colourants and bleaches on their hair can also have hair drug testing as the use of any of these chemicals on the hair has no effect on the results although this does not include unusually excessive amounts of these products being used on the hair. Hair growth is fed by the blood stream that is how it is possible to detect drug abuse from small amounts of hair analysis cut from the head.
