A hair strand drug test is among the most exact laboratory tests for drugs and alcohol and is almost
impossible to cheat.
The process can be used to discover virtually all drug and alcohol substances, between 7 days and 6
months after their use. The test result also shows the month in which a donor takes a substance, and
can therefore be used to build a ‘picture’ of substances use over time.
A little quantity of hair is taken by a trained sample collector, usually from the head (we only need about
a shoelace worth.)
If an individual’s hair is completely unsuitable for testing, body hair or fingernails can still be used for an
accurate result.
