Hair Follicle Test
The gold standard for legal proceedings, custody cases, and pre-employment screening. Detects drug use over the past 90 days with high accuracy and court-admissible documentation.
📋 About This Test
Hair follicle drug testing analyzes a small sample of hair (approximately 1.5 inches, cut close to the scalp) to detect drug use over approximately the past 90 days. Unlike urine testing which shows very recent use, hair testing reveals patterns of use — making it the preferred choice for attorneys in custody proceedings, family court cases, and comprehensive pre-employment screening.

❓ Common Questions
Will the hair cut be noticeable?
No. The sample is taken from the back of the scalp, close to the skin, in a small area that is not visible under normal hair styling. The amount removed is minimal — approximately the thickness of a pencil.
What if I shave my head?
If head hair is less than 1.5 inches long or insufficient, body hair (chest, arm, leg) can be used as a substitute. Body hair has a slightly longer detection window.
Can hair dye or treatments affect results?
Hair treatments such as dyeing, bleaching, or perming can affect the concentration of drug metabolites in hair but do not typically cause a false positive. Our laboratory accounts for this in its analysis.
Why does it take 3–5 days vs. 24–48 hours for urine?
Hair follicle analysis requires a more complex multi-step extraction and confirmation process than urine testing. The laboratory must physically dissolve the hair sample and perform multiple rounds of testing before results can be reported.
