It could be pretty challenging to pass a hair follicle drug test on the same day as you need to detox your hair properly first. If you are a light user, you should perform at least 5 Macujo methods one day before your actual drug test. For a heavy user, you need to detox your hair with a combination of the the Macujo and Aloe Toxin Rid Treatment methods at least 12-15 times.
