Hair testing can report finding five times greater of illicit drug use compared to urine laboratory based testing programs. This is one of the reasons hair drug test are becoming very popular among employers and the court system.

What time period does hair testing cover?

The typical length of head hair tested is 1½ inches from the root end. Since the average growth rate of human head hair is approximately ½ inch (1.3 cm) per month a hair analysis covers an approximate 90 day look-back time frame. Hair may be retrieved from the face, chest, and underarms as well.
