*’Hair bath’ is a term used in colloquial Indian English (Indianism) which means having a regular bath as well as washing one’s hair. Many people don’t wash their hair every day. Also, in India, the term bath doesn’t imply bathing in a bathtub; it could mean a shower, bathing from the bucket, or in a river; either way, it refers to the act of bathing.
