Hair drug screening, commonly referred to as hair follicle drug screening, is a methodical approach used to identify drug usage by evaluating hair samples.

How it works:

• Drug enters bloodstream: When drugs are consumed, the substance and its metabolites (breakdown products) make their way into the bloodstream.
• Drugs reach hair follicles: Since each hair follicle has an associated blood vessel, drugs are transported from the bloodstream into the hair follicle.
• Drugs get trapped in hair: As hair extends, these trace chemicals embed themselves into the hair's cortex.
• Hair sample collection: A hair sample is obtained, usually from the scalp (or body hair if scalp hair is insufficient).
• Lab analysis: The collected hair sample is dispatched to a lab for examination.
  • Screening: An initial Enzyme-Linked Immunosorbent Assay (ELISA) test is undertaken to screen for drug residues.
  • Confirmation: If the ELISA test shows positive, a more detailed confirmatory test, like Gas Chromatography-Mass Spectrometry (GC/MS) or Liquid-Chromatography-Mass Spectrometry/Mass Spectrometry (LC/MS/MS), is performed to verify the presence of drug residues and eliminate false positives.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug consumption up to 90 days prior, unlike urine tests which have shorter detection durations.
• Difficulty to cheat: It is quite challenging to deceive a hair drug test, enhancing result reliability.
• Provides historical data: It offers an overview of drug use patterns over time, not just recent consumption.

Limitations:

• Cannot detect recent use: It requires approximately 5-7 days for drugs to become traceable in hair.
• Cost: Hair drug tests tend to be costlier than other drug testing techniques.
• Variations in results: Elements such as hair color and individual differences in hair growth can affect the drug metabolite concentration in the hair.

Note: While commonly termed "hair follicle tests", the examination actually assesses the hair strand and not the follicle beneath the skin.
