There are few things in this world that I actually hate. [I tend to use the word "hate" loosely. I often exaggerate.] But I really do hate washing my hair. I have thick enough hair that I can hide greasy hair for about a week before I have to wash it. Yes, I know. one. week. However, there are just some days you can't bring yourself to wash your hair. And so, the fashion Gods created hats and made them trendy.
