maybe. that depends on the sensitivity of the hair test and the amount and location of the sample taken. very tiny amounts of cannabis may not be detected but i have no idea if you have a sufficient amount in your hair follicles to register a positive result. be prepared. the test could be positive or negative. cross your fingers and lay off the weed if you know you may be drug tested.
one hit of weed 2 months ago and before that one hit of weed in may will i fail a hair follicle test?
