I am applying for a job that requires a hair drug test. I took one hit about 2 months ago for the first time in about 4 years. Do you think I will pass? I have heard there won't be a high enough level of thc in my hair follicles. Just curious.

It is very unlikely that there is any THC or metabolite in your hair. THC and THC-COOH the active metabolites of cannabis have a very low incorporation rate into human hair (Auwater, etal 2010) with the result that low or infrequent cannabis use is seldom detected in hair testing (Musshoff & Madea, 2006 and DuPont, 2008 p. 8).
