Your new cut is beautiful! I, too agree that less expensive products can work just as well as more expensive products. I, too, also wish to say that you shouldn't restrict yourself to one product line. IME it's very rare to find a product line where every product they make will work well with one's hair. It certainly has never happened that way for me.
Very fine, high porosity, currently dyed and growing out the relaxed portions. I'm pretty sure my hair's 3b something IIRC. We will be finding out for sure as time goes by.
