bad hair day
A day when one's appearance, especially one's hair, does not look attractive. For example, What have I done to upset Martha? Nothing, she's just having a bad hair day. Originating as a humorous statement, this term was soon broadened to mean simply having a bad day, that is, a day when everything seems to go wrong. [Late 1980s] Also see not one's day.
