Hi Nebraskaman, I found this:

6. How soon after use can a drug be detected in hair?
It takes approximately 5-10 days from the time of drug use for the hair containing drug to grow above the scalp where it can be collected.

I'm not sure what can be done, if anything, for it to not show up - short of shaving your head and that could raise suspicion itself.

When do you have to have the test?
