Will I pass my hair follicle drug test?

I have an important upcoming hair follicle drug test in two days. The last time I smoked marijuana, which consisted of three hits of some good stuff, was on December 13th, 2012. Doing the math, it's been over 120 days. Before those three hits, I had been clean for 50 days. Prior to the 50 days, I was smoking moderately at least every other day for four months. I am 5'10, 185 lbs and lift weights frequently and run/walk most of the time as wel so I am fairly muscular and in good shape. I can not risk my body hair showing past use so I shaved it just enough to where it is too short to take a sample. I have gotten several haircuts since four months ago so I think my head hair would be fine. Thing is, it also isn't long enough yet. They told me they could take my facial hair, which is nowhere near as long as they needed. I shave my facial hair at least twice a week.

My question is that since I have taken three hits in basically the past six months, but smoked moderately before, would I pass a hair follicle drug test if they used either my facial hair or hair from my head?

Thank ya'll for your help and any past experiences ya'll can share.
