Depends when you cut your hair, if it's short than it won't be a problem, if it's long they can still pick it up. And your company can't say anything if you cut your hair-just don't make it obvious that you did it to alter your drug test.

Hair does grow 3-4months behind what you ate/drank. It's an excellent timeline, which is why they use it for drug-testing.
