Hair Test

Hair tests can reflect drug use as far back as six months or longer since drugs are incorporated into the hair shaft as the hair grows. However, most experienced collection facilities take hair within 1.5 inches of the scalp and discard the rest. This limits the detection history to about 90 days, depending upon the rate of growth of the individual's hair.

There are those people who attempt to circumvent a hair test by shaving their heads. Body hair can be used as an acceptable substitute in the absence of the required amount of scalp hair.
