I used to be very much in love with these products some years ago, but they got harder and harder to find. My favorites were the Hydration shampoo and the Reconstruct. The shampoo had SLES if I remember correctly, but it also had ingredients that help the hair to bind protein and therefore retain moisture. The Reconstruct was very moisturizing and I liked it better than the moisture treatment. The moisture treatment seemed to make the wet hair shed a lot for some reason. Several members, including me, had this experience. The Reconstruct is not a hard-core treatment at all, like I said very moisturizing.
I also tried the relaxer once at a JCP salon. At the time, I had been going to that particular stylist for about a year and we found that the relaxer did not straighten well at all. If you are a texlaxer, it might be perfect for you.
If you do a search, I'm sure you can find some of my earlier reviews. I also convinced discount-beauty.com to start carrying this line and I believe they still do at less than the normal retail price. I am glad to see these products again.
ETA: The leave-in was one of my favorite products of all time. How could I forget to mention that!
