System flush? Would you mind explaining.I did a home urine test last night and passed no problem so its not in my body anymore just my hair. I couldn't find tw but did get zydot and will use on day of test with baking soda.i did the first bleach but didn't redye. Will it affect my results if I wait until after the second bleach to dye back. I might be able to post pone until the following mon.day if that would even help. Currently doing jerry g method with macujo.
