Thread title is self explanatory. Do you use conditioner (also called cream rinse) on your hair? If so, how often? And what kind? I haven't used conditioner for a few months now. I have fine, straight hair; I found any conditioner I used would build up on my scalp. Someone recommended deep conditioning once a week or every two weeks, but I'm wary...there doesn't seem to be such a thing as an objective, non-commercially-influenced expert who could tell me "this product would be better for you than this one," you know what I mean?
