Okay so when I say conditioning, I mean when I use the Creme conditioning my hair feels like I've used a pretty good conditioner Sometimes when I am lazy I may use just that and add a leave in and rollerset. But I'm working on stopping that. I didn't like the Elasta Poo for relaxed hair- no slip and just average to me. Now as for CON sealing in moisture, I don't know about that since it leaves that Balsam coating which I don't think is so great for relaxed hair. I use it though when I am extending relaxers because nothing detangles like it. (I still haven't tried the soft sheen at 10 weeks post relaxer though so maybe I might admend this statement in a few weeks.)I think the balsam coats the strands and leads to great detangling but I don't think the detangling is due to more moisture, it seems to be more like something analgous to how cones coat the strand providing slip.
Before I found these other shampoos I was doing what you suggested, clarify, CON and condition. But to be honest the only condition I like with the CON poo was the Elucence Emergency Repair Treatment. I didn't even like the CON conditioner with it. Some other ladies here like that combo though.
