How can you wash your scalp without shampoo?

You can use other gentle cleansers that are great for lifting the build up on your scalp without stripping your hair of its moisture. Some of these include Apple cider vinegar or clay washes. You also always use conditioner as a cleanser, although you have to be careful not to use a conditioner that has a lot of silicones in it, because it can create a barrier around your hair strands that prevent moisture from coming in.
