I don't know if I can help yet, I need a little more info. What do you want to do with it? Are you trying to clean deep within the strand? Remove buildup? Prep your hair for some kind of processing?

I don't know if this will help at all, but this article says that a clarifying shampoo can be helpful to prep the hair to accept processes. I'm wondering if a chelating shampoo is what you want. Although it doesn't actually open up the cuticle, it will remove any deposits that have built up making the hair more accepting of processes.
I hope someone else who can help better than I can will chime in.
ETA: I happened to find this when I was searching for the answer to your question. Look in the first post for info about baking soda and water. I didn't read the whole thread though.
