I'd have to agree with the raves contained in the thread Sweetcocoa posted above. The whole product line works well for me - the shampoo, followed by the moisture repair, then the moisture balance. I've mixed and matched but this is the only combo that leaves my strands smooth (i.e., without 'chips' or divits, if you know what I mean?). I like it even better than Aubrey Organics' GPB, which I NEVER thought would happen. The Elucence Extended Moisture Repair and AO GPB are my two protein staples. They've curbed my desire to look at any other protein conditioners.
Edited to say:
I believe the Extended Moisture Repair serves as a protein conditioner although, like the AO GPB, I find it to be one of the more moisturizing protein conditioners for MY hair. However, if I'm looking to apply solely a moisturizing conditioner for my hair, I would use the Moisture Balance conditioner instead.
