Unlike urine tests, hair samples are not easy to manipulate. Drinking large amounts of water or some drinks which may interfere with the drugs being tested can affect the urine sample but not the hair sample.

What are the advantages of using a strand of hair for a drug test?
The ability to see past drug use from the last few years. The inability of the subject to hide their drug use by using masking or cleansing agents. There is a shampoo you can buy for this test but I have zero feedback on it. Ive used both urine masks and mouthwash for swabs but no experience with the shampoo. Any employer that uses a hair test for hiring new employees is overstepping their "right to know". How sad is it that privacy means so little these days. Soon the government will butt their noses in a little more and these types of tests will be the norm, it will probably end up somewhere in the ever changing and unconstitutional Patriot Act. Thanks Bush!
