I had a hit of weed one time four weeks ago. What should I do if I have a hair drug test on Tuesday?
What about drinking a lot of water or exercising to flush it out of my system?
Unfortunately, drinking a lot of water or exercising will not remove THC from your hair. THC molecules bind onto hair proteins and stay in the shaft until that hair is cut or falls out. Drinking a lot of water or exercising may help to detox in other areas of your body, but it does not affect hair drug tests.
