Order Hair Drug TestThe Hair Drug Profile examines hair specimens for evidence of drug use.

The profile is used in a range of settings, from clinical and forensic work to workplace screening programs.
About Hair Drug Test in Normal
Hair testing works on a simple biological principle: as hair grows, compounds circulating in the body can be deposited into the follicle and become trapped in the forming shaft.
A sample is collected by cutting a small section of hair close to the scalp, typically from the back of the head where growth is most uniform. The sample is sealed and sent to a laboratory, where it is washed to remove external contamination and then processed to release any substances bound within the shaft.
The window of detection depends on hair length and growth rate. Scalp hair generally grows at roughly half an inch per month, so a sample of standard length can reflect a period of approximately ninety days. Because the shaft preserves a chronological record, laboratories may also perform segmental analysis, dividing the sample into sections that correspond to different time frames.
Results are reported as either negative or positive, with positive findings often including the class of substance detected and, in some cases, an estimated concentration. The test does not measure impairment or current intoxication; it indicates whether a substance was present during the period represented by the hair sample.
