Will hemp shampoo make my hair test positive for marijuana?

Hemp shampoo will not cause a false positive on a hair test for 2 reasons.

1. The hair test looks for metabolites of THC, not actual THC.

2. THC levels in hemp seed oil are in the low parts per million or even lower. Hemp seed oil is only a minor ingredient in the shampoo so it is far more diluted than straight oil. THC levels (if any) in a hemp shampoo would be immeasurable.

More info on hemp and drug tests at http://www.TestPledge.com which is a hemp industry standard for THC levels in hemp food and bodycare products. TestPledge assures consumers that they won't test positive for marijuana on a drug test. Many hemp companies have voluntarily signed on to the program and pledge to test each batch of their product for compliance with the science based standards.
