Yes, Max for the full-heads and most of the root apps, then Gold for the last 3 root apps. I still believe that Max is just as effective as Gold. I don't have a point of reference for the fume strength, but I don't even use a fan when I do my roots...just the overhead bathroom fan and open the bathroom window. When I do the full head, I use a big floor fan and direct it at across my face during the blow drying segment. They can make my eyes burn somewhat fiercely if I aim the blow dryer the wrong way, but not badly enough that would ever discourage me from doing the BKT. But, hey...apparently I'm willing to risk cancer to have manageable hair...that should show you the level of my commitment...or the depth of my crazy!
