How am I going to wash my hair?

I have been trying to figure out ways to wash my hair after my surgery. Seems like so something so simple to worry about. But really, how am I going to when I have an incision from top to bottom?  So far, I have thought about going to a salon. Easiest choice but, my incision will be to high and I won't be able to lay my head back on the sink. Then there is that contraption that you attach to a facet and it becomes a shower head. I would have to lay over  a chair, stomach down, and have someone wash my hair for me. Finally, dry shampoo. It would be okay for a couple of days but a week or two...I don't know about that. I've even heard to put cornstarch or baking soda in your hair to soak up the oil. Hey, I might have to give it a try.

I am probably going to stink! LOL
