12 month hair follicle test, 3 months clean chances of passing?

Hi Cannabis community,

In a couple weeks from now I may be having to take a 12 month hair follicle test for a job. I have been clean for over 3 months now and I was wondering if anyone has ever been in a similar situation and also wondering what do you think my chances of passing are? I have a feeling they are going to take it from my arm pits, but just to be safe I was planning on cutting all the hair on my body short today and let it grow out as much as I can before the hair test. Any feedback or suggestions would be greatly appreciated. Thanks CC.
