The test can go back as long as your hair is long. The average growth rate for hair is 1/2 inch every month. So if they take 2 inches of hair - they can test for four months worth of drug usage.
With said, however, the average hair drug test will go back for 30 - 90 days. The longer the hair is, the less accurate the test will be.
A standard hair follicle screen covers a period of approximately 90 days, but is susceptible to time variation depending on the growth rate of your hair. The hair sample is cut as close to the scalp as possible and the most recent 3.9cm (or 1.5 inches) are tested. It is possible to go back even further than 90 days since the time period is limited only by the length of the hair sample, but is standardized to a 90 day history.
