Hair drug testing, also recognized as hair follicle drug testing, is a scientific technique employed to identify drug use by examining hair samples.

How it works:

• Drug enters bloodstream: Upon drug use, the substance along with its metabolites (breakdown products) infiltrate the bloodstream.
• Drugs reach hair follicles: Due to each hair follicle having a blood vessel, drugs migrate from the blood into the hair follicle.
• Drugs get trapped in hair: As hair grows, these minute amounts of chemicals are deposited into the cortex of the hair strand.
• Hair sample collection: A hair sample is collected, generally from the head (or body hair if head hair is insufficient).
• Lab analysis: The hair sample is dispatched to a laboratory for examination.
  • Screening: An initial Enzyme-Linked Immunosorbent Assay (ELISA) test is conducted to screen for drug metabolites.
  • Confirmation: Should the ELISA test yield a positive result, a more definitive confirmation test, such as Gas Chromatography-Mass Spectrometry (GC/MS) or Liquid-Chromatography-Mass Spectrometry/Mass Spectrometry (LC/MS/MS), is carried out to verify the presence of drug metabolites and eliminate false positives.

Advantages of hair drug testing:

• Long detection window: Hair drug tests are capable of detecting drug use for up to 90 days, whereas urine tests offer a shorter detection timeframe.
• Difficulty to cheat: Due to its complexity, it is exceedingly challenging to cheat a hair drug test, thereby enhancing the accuracy of results.
• Provides historical data: It can reveal a pattern of drug use over time, instead of reflecting only recent use.

Limitations:

• Cannot detect recent use: It requires approximately 5-7 days for drugs to become detectable in hair.
• Cost: Hair drug tests generally incur higher costs than other drug testing methodologies.
• Variations in results: Factors such as hair color and individual differences in hair growth may influence the concentration of drug metabolites in the hair.

Note: Although frequently called "hair follicle tests", the examination actually analyzes the hair strand rather than the follicle beneath the scalp.
