I was liking my “fun bun” so much that I wanted to experiment with a slept-on version of it the next day—but when I awoke, I had a throbbing headache. What I thought was a hangover turned out to be said fun bun pulling on my temples and my eyebrows. (Note to future self: This could be a less scary alternative to Botox.) As I untied the string, and my forehead slowly lowered about three inches, it felt much like undoing a corset at the end of the night. Updos are certainly fun, but they don’t fare particularly well in the light of day. That said, would you go to a black-tie dinner in a sack of a dress simply to avoid a little discomfort?
