"I'm Gonna Wash That Man Right Outa My Hair" is a song from the musical South Pacific, sung by Nellie Forbush, the female lead, originally played by Mary Martin in the 1949 Broadway production.
Her character, fed up with a man (Emile De Becque) and singing energetically in the shower, claims that she will forget about him.
She had starred on Broadway for years and Martin suggested that she wash her hair on stage during the performance.
[1][2] PJ Harvey referenced the song in her 1992 single "Sheela-Na-Gig" with the repeated lyric "gonna wash that man right outa my hair".
[4] Clairol created an ad campaign in the 1980s using the song with the alternative line "I'm gonna wash that gray right outta my hair."
