I am going to take credit for inventing this phrase. When I was in elementary school, I coined the phrase "hair day" (as in GOOD hair day) on certain days when the air was clear and the sun was bright -- it made everyone's hair look shiny. I would tell my friends, "Today is a hair day!" The phrase was quickly picked up and expanded to "Good Hair Day". This was in Beverly Hills, back in around 1969.
I believe that "Bad Hair Day" came as an offshoot of that. Call me crazy, but I swear this happened!!
