Hair Follicle Drug Test Introduction

When taking a hair follicle drug test, the facilitator will remove a small hair sample from near the scalp and send it away to a lab for testing. Because there are some compounds within foods that can give a false-positive result, hair follicle testing undergoes a two step screening process for accuracy. The first step is a rapid screening method. If the rapid screening method comes back positive, a second type of test will be done to determine the legitimacy of the results. Lower, you can see products that are used for this method, Old Style Aloe Toxin Rid and Zydot Ultra Clean.

Test results are typically labeled as negative, positive or inconclusive. Negative means the test did not detect any drugs within the hair sample which is also called passing the drug test. Positive means that both the first and second test confirmed presence of a certain drug within the body, which could be interpreted as failure of the drug test. Inconclusive means the sample is contaminated or that there is an issue with the testing which inhibits the ability to gain results. In the case of an inconclusive test, the lab may request a second sample.

Regarding hair follicle drug test detection times, the hair follicle drug testing is used to determine whether a person has used a particular substance within the last 3 months. It cannot however determine the exact date of use. This is because hair grows at differing rates for each individual.

Factors affecting the sample and the metabolites detected:

  • the drug compound structure
  • the quantity of drugs consumed
  • If a person sweats a little or profusely
  • How much melanin (dark hair pigment) is in a person’s hair because certain drugs bind more easily to melanin
  • If a person bleaches or colors their hair
