If you took 3 little hits of weed and didn't inhale very long will it show in hair folical test?

While THC can be detectable in hair follicle tests, taking just 3 small hits where you didn't inhale deeply may result in lower levels of THC in your system, which could potentially be below the threshold for detection in a hair follicle test. However, the detection window for hair tests is longer than other methods, so it's not guaranteed that it won't be detected.
