Hair Follicle Testing

Hair Follicle testing is the superior method for determining substance abuse. This highly accurate drug testing technology offers a wide range of detection time frames that can approximate the pattern and quantity of drug use.

SureHire’s partner, Psychemedics, the only CSA (Canadian Standards Association) approved hair testing laboratory in North America,  provides a gold standard testing panel that includes:

  • THC
  • Opiates
  • Amphetamines
  • Cocaine
  • PCP
This panel provides the following testing time frame options:

  • 30 Day
  • 60 Day
  • 90 Day
  • 180 Days (6 Months)
  • 365 Days (12 Months)


How soon after use can a drug be detected in hair?

It takes approximately 5-7 days from the time of drug use for the portion of the hair containing that drug to grow above the scalp.

How much hair is needed?

To complete a standard 90 day hair follicle test, a minimum of 1.5 inches is required (0.5 inches per month). The amount taken is usually cosmetically undetectable and can be compared to the thickness of a shoelace tip. 

If I do not have sufficient head hair, can body hair be collected?

SureHire does not accept body hair as an alternative collection method when head hair is unavailable or insufficient.
