Hair testing is a reliable method of drug testing that involves analyzing a hair sample of approximately 90-120 strands of hair, and 1.5 inches in length collected directly from the test subject’s scalp.​

  • ​Hair drug testing offers an accurate way to screen for drug usage within the past 90 days.
  • If the sample provided is body hair, this type of test can even screen for drug use within the past year.
