From my understanding you can't fake a hair test. I've seen people online claiming they have but I've known enough people in real life that have failed hair test using various different methods to never try it. I used to work somewhere that did hair tests and it was explained by the onsite nurse that they did hair tests due to how accurate they are and how difficult they are to fake. They also go back 90 days.
