Thanks Jerry, I didn't know that. I always see the TW/ BW for around $70-80 a bottle and I thought the directions were to use the whole thing. The vender suggested to use the whole bottle, maybe 2, as well as some hair mud that could also be purchased. The direction do say though to use once and repeat so that would seem (2 oz total on average) to be equivalent to 1 box of Zydot.

When you did your experimental test runs, for the biowash or toxin wash how were you doing it, the lather rinse and repeat or just one washing?
