I used various methods to remove drugs from my hair. The problem with the Jerry G method is that it uses ammonia hair dye as the basis for it. Although it works, it can damage the hair shafts permanently unless you get it right. However macujo.com is far better, if you go for a job interview with one color hair, and then you turn up for hair drug test two days later with freshly dyed hair of the same, or worse a different color, then that’s going to raise an incredible amount of suspicion!
