Retreating and for shampoo, should I be adding water to my hands?

Add water to hands only for pretreating, where there is no water
already there to help you along, otherwise in re-treating and
shampooing it can cause improper and sporadic absorbtion, it will also
make the hair feel odd, it will be unevenly applied. Thus i remind you
no spraying with a spraybottle either, so water used on hands for and
with pretreats, no water on hands (water in hair already) with
everything else:-)

Pretreating we want to taper it out, not actual mixing.
