I have a pre-employment screening tomorrow plus physical so not sure if it's urine or hair, but i had a friend call up there and they have 2 types of hair tests and 1 urine test. I've done the macujo method 4 times in the past 4 days and i did the Idavisa method with pantene nature fusion w/ aloe and i added a little aloe vera gel to it just in case. I'm strictly an herbal person and been clean of everything for about 10 days, passed a home urine test today so I think i'm clear for now. I plan on doing the Idavisa method one more time before I go in tomorrow and also using zydot shampoo. I'll post results when they come in.
