You only need to wash your hair once per day, after ten days let the shampoo soak in and give it a firm massage before washing it off. Spraying water to the area at this stage is pointless, just shower the scabs away.
In some case`s your transplanted hair will continue to grow but for the vast majority it will fall out approximately 14 days post op.
Growth and result wise, you will just have to wait and see now.
Best of luck.
