Wrong again!!!!! Even it you cut your hair and new hair grows your still going to have thc in your system. It sticks to your pores. And also with a hair drug test, it goes back up to 8 months!!! And how do I know this info u might ask? ItS cause I took a hair drug test and failed it, the guy told me all this wonderful information. Your best bet is to buy a detox shampoo and use it on your head when the hair is long enough and b4 you take the test.
