Hair Drug Test


Hair Drug Test

All about the Hair Drug Test Process and when Hair Drug Testing is Suitable.

It is becoming increasingly common for employers and the courts to ask for a Hair Drug Test. Testing for illegal substances in hair gives you a greater time frame of detection than urine, blood and saliva. In fact, you can often detect drugs in hair for several months – if not years, if the hair is long enough. The most common request we have for hair testing is a 3 month or 90 day history of drug use or abstinence, requiring a 3 cm (1 ¼ inches) length of hair sample. It is possible to test less than one centimetre up to any length of hair sample available, however we have to section longer hair samples into maximum 3 cm sections, to maintain the sensitivity of the hair test. As a result, the profile of drug use can range from approximately 7 or 8 days history up to in excess of 2 years (if the person’s hair exceeds 24cm in length).

How much hair is required to carry out a hair test?

About 50 strands of hair are necessary – obtained from the crown of the head, which is about the width of a thin pencil, or perhaps the tip of a shoe lace. There are typically in excess of 100,000 strands of hair on the head of the average person, so this should not make any cosmetic difference, unless the individual’s hair is very short.

Hair Drug Test benefits:

  • Hair Drug Tests detect drug use over months, not days.
  • Collecting a sample for a Hair Drug Test is very simple and non-invasive.
  • Monitoring abstinence is possible over a length of time.
  • Hair testing results stand up in court.

Are there disadvantages to carrying out a Hair Drug Test?

The two main disadvantages to hair testing are cost, and the time frame necessary to get results. It takes several days to digest the hair sample to a stage where it can be analysed, so we have to quote up to 10 working days on any hair analysis. In terms of cost, we charge £65 plus VAT for the sample preparation (which takes about 3 days) and then £45 plus VAT per drug per section. There are a choice of about a dozen drug classes, but 1 or 2 main ones are common.
