Hair drug testing, or hair follicle drug testing, is a scientific approach used to identify drug consumption through examination of hair specimens.

How it works:

• Drug enters bloodstream: Upon drug usage, the compounds and their metabolites (breakdown products) infiltrate the bloodstream.
• Drugs reach hair follicles: Due to each hair follicle possessing a blood vessel, drugs travel from the blood into the hair follicle.
• Drugs get trapped in hair: As hair grows, these trace chemicals are embedded into the hair strand’s cortex.
• Hair sample collection: Hair is sampled, commonly from the head (or body hair if head hair is inadequate).
• Lab analysis: The hair specimen is dispatched to a lab for evaluation.
  • Screening: An introductory Enzyme-Linked Immunosorbent Assay (ELISA) test screens for drug metabolites initially.
  • Confirmation: When the ELISA test is positive, a precise confirmation test like Gas Chromatography-Mass Spectrometry (GC/MS) or Liquid Chromatography-Mass Spectrometry/Mass Spectrometry (LC/MS/MS) is performed to ascertain drug metabolite presence and rule out false positives.

Advantages of hair drug testing:

• Long detection window: Hair drug tests identify drug use up to 90 days, unlike urine tests which have a shorter detection span.
• Difficulty to cheat: Hair drug tests are notably challenging to manipulate, enhancing result accuracy.
• Provides historical data: It offers a pattern of drug use over time, not merely recent usage.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair approximately 5-7 days post-use.
• Cost: Hair drug tests are typically pricier than alternative drug testing methods.
• Variations in results: Elements like hair color and personal differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: Despite being called "hair follicle tests", the test itself evaluates the hair strand, not the follicle beneath the scalp.
