A few years ago, as I chatted with my friend about which color I should dye my hair, I was given an unexpected lesson in beauty terminology. She was in cosmetology school at the time, and I knew she'd have some good ideas. Instead of guiding me towards something like, "chocolate brown with copper highlights," she said something more along the lines of, "You dye an Easter egg, not your hair. You color your hair." Well, excuse me.

It was something she had learned in school, she told me — the professional beauty lingo, you know. Oh, she also mentioned that when it comes to plucking, that's only for chickens, not eyebrows. Instead, it's tweezing, and tweezing alone. Righty-o then.
