What if you're having a bad hair day?

I was on youtube the other day and came across videos on how to fix a bad hair day. Most of them went on and on and I don't see how it would help messy, knotty, frizzy hair. Plaiting or braiding won't help & curling/straightening will definitely not help either! If you're having a bad hair day, I think the easiest thing to do is tie it up or bun it. lol
