I never tried any of the MD stuff :-) got way too much in my stash as it is, can't comment on that. HB Fix is a treatment conditioner & may just be too much for your hair in general. SS cej & FHG are protein free you should be good! Nope no more ideas sounds like you have a good plan sticking with CJ rehab.
