I'd like to know if doing two bleaches and redyes will get me clean or do I have to use the mac as well. I cut my hair to my shoulders, it was to the middle of my back and did two mac treatments, didn't feel any different after the macs, so I bleached and am planning to redye and will repeat the process in a week. Wanted to know if I need to do anything else, like a baking soda paste wash or the bleach/redye should suffice?
I am 5' 6" and weight 110 lbs, so very high metabolism and I'm very active. I have thick black curly hair, and I was a six year very heavy smoker till the end February ( an ounce of shwag a week). I slowed down A LOT in March and stopped totally 10 days ago. I have scheduled my test for the 15th of May and will use the Zydot on the day of. That will give me 38 days clean with two bleaches and redyes and one Zydot treatment. I'd like to know also if I should bleach and redye in a week or wait till the day before my test to do so, are two bleaches and redyes enough or do I need to do another one? I don't want to torture my hair any more than I need to, but my future depends on this hair test. Any input will be greatly appreciated, cause I'm worried sick.
