Will Marijuana Show In The Hair Test?

I smoked marijuana 2 weeks ago, maybe 3 grams and again a month ago, roughly 3 grams as well. Prior to that I have been clean for over 6 months. I shaved my head last week and have a hair follicle drug test in roughly 3 weeks. Will I be able to pass the hair test?

Right on the border.
If someone chronically daily smoked. You would really have a tough time passing the test and it would take at least a month clean for it to be out of your system and then time to Start growing hair.
With rare use, marijuana is out of the system in under a week, but hair test is very sensitive; it's borderline. If you had 3 week between use and Starting to grow hair, probably ok.
On the Other hand, you don't have enough hair to test. The marijuana is more likely to be at the ends than at the base (*earliest hair*).
Tricky.
