All About Hair Testing

A hair drug test is the most accurate procedure of doing a drug test. Hair testing can be used to show regular substance misusers. The necessity for a hair follicle drug test has steadily increased of late and is widely used and approved by the UK courts.

A hair drug test not only detects the residence of an illegal substance, but it can also provide an an accurate record of drug abuse. This helps in differentiating between a one-off user and a ceaseless substance abuser.

Using a small lock of hair collected from the scalp, hair testing assesses the number of drug metabolites embedded inside the hair shaft.

How Does Hair Testing Compare with Other Drugs Tests?

Compared to alternative types of drug testing (i.e, urine sample testing), a hair drug test can uncover a longer time frame of drug use. With these other drugs tests, drugs are undetectable after just a small time frame.

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