I used CPR when I was relaxed and I found it was pretty good for stopping breakage. I didn't do a follow up with a moisturizing condit either, probably because I didn't know about those then, and I never had a problem. I haven't found that it's the most effective on natural hair, but oh well, I've moved on to other products anyway.
On a side note, Motions has two lines, the "At Home" line and the "Professional" line. You can always get the "At Home" line in BBS, but the "Professional" is a little harder to get your hands on. The only "Professional" product I can remember seeing in a BSS was the Moisture Plus conditioner in the big tub.
