Is it possible to pass a hair test without exspensive detox shampoos

Me and my roommate are both going to have a hair folicle drug test. I plan to use the macujo method and bleach and redye. I smoke one a day for the past 3 years. I have dark hair 25 years old.

My roomates hair is dirty blonde and very fine. She hasn't smoked but has been around it and in tons of hotbox rooms her entire life. She plans to just use the macujo method.

What I'm worried about... We don't have toxin wash or zydot. Everything around here is very exspensive and/or not one of the most successful detox shampoos. Is it possible to pass without these?

IMO yes, I just used paul michele 3 and nuetrogena tsal except for on test day I did use zydot. If you can it would hurt to use one on test day but I dont think its a key part, you can read up on my threads and see what I did

We don't have tsal here. We have t gel wich I have bought and used. I also couldn't find the Paul Mitchell 3 and have been using a clarifying shampoo called ion with tea tree

Found some denoted with 3% salicylic acid. Almost the same thing??? Has anyone been through this?? What are my chances? I'm panicking.

How Long will you have been clean by test day. I don't know of any science backing this theory but exercise couldn't hurt to get it out of your fat.and yes the acid is whats important so that'll do. My advise is to do as much as you can of everything without noticeably damaging your hair
