I'm not sure we're talking about the same thing?? Are you doing this in one step or are you wetting, co-washing, rinsing, then adding more condish?
One of the benefits (again this may be more for the porous heads) is that my drying time is cut in half! I credit that to the spritzing & adding condish as opposed to doing a full wet down washing, rinsing then adding more condish.
