I had a hit of weed one time four weeks ago. What should I do if I have a hair drug test on Tuesday?
Okay, that makes sense. Can a haircut help at all?
Yes, a haircut may help to remove some of the traces of THC in your hair, but it is not a guaranteed method of passing a hair drug test. Hair grows at a rate of approximately 0.5 inches per month, so if you had only one hit four weeks ago, it may be better to wait until you have more hair growth before taking the test. Cutting your hair too short may also raise suspicion during the testing process. It's always best to consult with a medical professional or drug testing expert for further advice specific to your situation.
