What do you do on a bad hair day or when your hair is greasy and don’t have dry shampoo or time to wash it?

I braid my hair into a ponytail on a medium height on my scalp and slick it back with water and hairspray. Then I braid the ponytail and pull out some strands of hair to make it look better. Putting it into a slicked back yet messy bun or clipped up is also an option.
