The word toupée has a twisted derivation. It ultimately comes from the prehistoric german word *topaz, which means 'tuft of hair on top of the head,topknot'. the German word was imported into French and we had the word toup meaning 'tuft of hair'. This ultimately gave way to the word toupée, which was imported into English.
Just remember the answer to the question, 'what does a bald man need'?
