Drug Testing Help - Questions for those who have done it before.

Okay, so I've seen a lot of posts on here about people passing drug tests, and I've tried their methods, but I was wondering if any of you experts can answer some questions of mine.

Background: I've smoked maybe 10-15 times in the past 90 days. Each time was not even a full bowl, ungrinded weed, like two-four strong hits. So I got high, but only a little. The last time I smoked was 2 weeks ago, and my test is in one week.

I have thick, curly hair. I've washed it with Zydot once already, and plan on doing so again the morning of the test.

I've done the Macujo method to the full extent twice now, but each shower I've been washing my hair with TSal, Dawn, Tide, etc. without necessarily doing the full soak/vinegar whatnots. I didn't soak it in a shower-cap, I just towel wrapped it. Does that matter?

I've noticed a mild burning, my hair is frizzier than before, and the artificial color has faded some. People talk about when they do this method how it BURNS and their hair is "fucked" so I'm worried that I'm not doing it right? My hair seems angry, but not like "oh god I need to cut this shit off my head it's so dead" levels of fucked. I've been using an excess amount of Pantene Pro-V Night Miracle, both the conditioner, and the leave-in conditioner.

Am I doing it wrong? I'm going to bleach my hair, dye it back to my color tonight, and then macujo method every day until the test, where I will Zydot it, soak it in conditioner, and then go take the test.

Any advice?

Edit: It should be noted that the times I smoke were never consecutive. I know I've read a lot about it not catching "one time users." My smoking was like once a week.

Does anybody know where they take the hair from? I was going to bleach the shit out of my hair, but I don't like doing that to the top of my hair.
