Good question. I don't know how everyone else does it. But I like to apply the DT to washed damp hair, but there are times I apply it to dry hair. I feel though when it's wet/damp, the DT sinks in better. I leave it overnight usually once a week. I co wash and then apply the DT and leave it in overnight. In the morning I just rinse it out and then do honey rinse and that's it. I feel if I condition again I may overcondition so I don't do that.
