Hair follicle drug testing is highly reliable due to its long detection window and the scientific analysis of hair samples. The involvement of five national lab networks and review by certified Medical Review Officers adds layers of quality control. The test is not affected by passive exposure and cannot be diluted like urine tests. Detection window up to 90 days Certified labs with strict protocols Non-negative results reviewed by Medical Review Officers Unaffected by passive exposure Difficult to adulterate or cheat For DOT-regulated safety-sensitive positions, hair testing is only for non-DOT roles; DOT urine testing follows federally certified protocols under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). TEST LIMITS ## Are there limitations to hair follicle drug testing? Hair follicle drug testing has some limitations. It generally cannot detect drug use within the past 7 days, as hair needs time to grow above the scalp. It may not detect very recent or one-time drug use. Also, cosmetic treatments like bleaching can affect results, but certified labs account for these factors. Detection window starts approximately 7 days after use Not for immediate or recent drug use detection Cosmetic hair treatments may impact results Sample collection requires sufficient hair length (about 1.5 inches) Call (877) 731-6362 to discuss if hair follicle testing fits your specific situation or if alternative testing methods are recommended.
