Etymology

The word "hairdo" is a compound formed in the early 20th century, combining "hair" (from Old English hǣr, meaning "hair") and "do" (from Old English dōn, meaning "to perform or arrange"). The term reflects the colloquial use of "do" to mean "style" or "arrangement," as in "do one's hair." It emerged during a period when elaborate hairstyles became fashionable, particularly in the 1920s–1940s.
