Wigless → It is formed from "wig" (from Old English *wigg*, meaning a covering for the head) and "-less" (meaning without). The word "wigless" means without a wig or lacking a wig.
Think of someone who is 'without' ('-less') a 'covering for the head' ('wig'). This helps you remember that 'wigless' means not wearing a wig.
