I have been using the same co wash and rinse out since I started, I guess it just works fro me right now and I am a bit too lazy trying to decide what to use early in the morning :-)
Now my daughter (13) is a whole different story, right now she is rotating at least 6 different conditioners. When I ask her why ( the shower looks like the shampoo isle at target lol ) , she says she can tell which conditioner her hair needs when its wet. Beats me, her hair looks great though whatever she's using.
