How do you hide a bad hair day? Share your tips!

I tried all the typical options: ponytails, buns, headbands, scarfs, clips and so on. (I ultimately washed my bangs and found a bun my hair would agree to, but I still didn't love it).
What are your tips for taming a bad hair day? Do you have any go to hairstyles or favorite products? Do you just deal with it and let it go?
