They don't check for DNA when they do a hair test or any other drug test. Any test they run on a sample from your body they have to tell you what they are testing for and actually get your consent. If you don't give the consent for drug testing then you don't get the job. If your hair is too short then they will look for body hair or they can even use fingernails. I think most collectors like at least 1/2-3/4 of an inch or they will go elsewhere for the sample. They can go back about 3 months which is 1 & 1/2 inches of hair. How much have you been smoking in the last 3 months? What kind of hair do you have?
FakeBoobsRule Reviewed by FakeBoobsRule on . hair shampoo Does anyone on the board that has beat a hair test with a shampoo? I heard bleaching works but kills the DNA and thats a give away for a test. I got this job working at a chemical refinery and they just switched to doing hair tests (AHHHH). I am not going to shave my whole body. I have smoked one joint yesterday thats it in the past 2 weeks. I don't want to spend $40 on this shampoo if it most likely is not going to work. I think maybe if I get a haircut (not shaved) and then buy that Rating: 5
