I've just passed hair test. I bleached an redyed 3x within a month. I used toxin was after each bleach and redye. Then I put the most potent perm lotion on my ed and ended up fucking my long hair up so badly I had to have it cut so short I ended up looking like a lesbian!! I used toxin was again after perm lotion. My hair was like a brillow pad, but I didn't care, I had to pass. On day of test I used toxin wash and zydot. Worked for me..... My test wasn't for a job it was was something far more important. I had 6wks to get it clean. I was a daily smoker of gd grade. These tests can b beaten.
