A hair follicle drug test is the most precise form of carrying out a drugs test. A hair test can be used to prove constant substance users. Although Hair drug tests can be pricey, it is a very accurate form of drug testing. The need for a hair drug test has steadily elevated as of late and is often used and accepted by the UK courts.

Hair drug testing not only verifies the presence of a illegal substance, but it can also accommodate a specific record of substance misuse. This helps in differentiating between a one-off user and a routine substance abuser, it can also help to monitor abstinance.

By obtaining a small sample of hair pulled from the scalp, about 50 strands or the width of a small pencil, a hair follicle drug test assesses the number of drug metabolites found inside the hair shaft, and can tell you in what time period the drugs were taken.

How Does A Hair Drug Test Differ from Other Tests?

Compared to alternative types of drugs testing (i.e, urine testing), hair tests can expose a greater period of drug use. With these other drugs tests, drugs are only detectable for a small time frame.

With a hair drug test , the only limitation for discovering drug usage is the length of the donor’s hair. Every half inch of head hair in length provides a 30-day history of drug abuse.

Overall, hair testing is best to use when trying to establish the time frame of drug abuse and to get a test that will stand up in court. It has both advantages and disadvantages including being very accurate but expensive, it stands up in court but it only tests for one drug per payment. There are many companies that specialise in drug testing, who would be more than happy to give advice on hair testing, any drug tests or queries about drug testing or drugs in general.
