hair sample
Lock for testing
A hair sample is a small quantity of hair collected for analysis.
Hair retains traces of substances over time, making samples useful for drug testing, DNA identification, and forensic investigation: The lab requested a hair sample to check for long-term drug use.
Unlike blood or urine, hair provides a longer detection window—sometimes months of history.
