Disgustingly greasy bangs overnight?

I washed my hair the day before last, but wake up today to find my bangs disgustingly greasy, to the point it's like gel (I can stick them straight up!). Any way to fix it? before bangs I could go this long without a wash, guess not now. Plumbers are fixing stuff and cut off our water, shower is a no go. Will baking soda work as a dry shampoo, or will it make my brown hair white? I don't wanna wear my bangs back, hate how I look without em.
