Surface Forms
Morphology
The phrase's meaning — a day when one’s hair looks untidy or is difficult to manage — is directly built from the constituents 'bad' + 'hair' + 'day' and requires no idiomatic inference beyond the literal senses. This compositional pattern is common cross-linguistically, so an average B1 learner who knows the words would readily understand the expression.
Etymology
Bad hair day paints a simple picture: your hair is messy or will not behave, and that small problem can make you feel embarrassed or annoyed all day. So, the phrase now means 'a day when your hair looks untidy and this affects how you feel'.
