Just an update, I did my second bleach today and will dye it back tomorrow. I washed it out with Neutrogena T-sal and PM3 after doing the 1st 3 steps of the mac (my hair is almost white). With my background will 2 bleaches be sufficient or should I do more? I have a job interview for another company monday but doesn't seem as good as my current offer so hopefully I'll pass the test. Would delaying the test 4 days make much of a difference? I ask because I planned on going on vacation but might have to miss it if I take the test on 8/5 instead of 8/1.
Current plan is to continue doing the mac until test day then on test day use zydot instead of PM3. If I feel like i can afford/ need another bleach I might but I don't think I will

Need answers to my questions, time is running out... Please help
