I know this has been asked about a million times, but my question is a little different. I have a hair follicle test coming up and I smoked a little marijuana about a month ago (3-4 hits off one bowl) and I know you've said THC is hard to detect in hair follicle tests but it seems you are referring to the hair being taken from the head. I shave my head so ill have to use my body hair, will that make a difference in the result of the test?
