I had not smoked pot since feb. 2nd. I know the hair test goes back three months, but I slipped on on Cinco De Mayo and smoked about 3-4 weak resin hits out of a bowl. Do you think it will show up in my hair test? I have some Test-In shampoo, and am going to get another kind too. Does anyone have experience with any of the shampoos good or bad? Please don't respond that I shouldn't have smoked, I know that. Any advice I would greatly appreciate it
