there is a thread about this somewhere on the board
basically I dont do it because I want to clarify my hair of styling products so the DT can absorb into the hair better. I just make sure to squeeze out the excess water after I shampoo so my hair is not loaded with water and prevent absorbtion of the conditioner.
