A small piece of false hair a man wears to cover a bald patch — usually the top or crown of the head, not the whole scalp. That is the key difference from a wig, which covers everything and which anyone might wear; a toupée is a patch, and is nearly always a man hiding hair loss. Because of that, the word carries a faint comic edge in English. There is a long tradition of jokes about toupées slipping, blowing off in the wind, or being obvious to everyone except the wearer, so calling something a toupée can sound like teasing. If you want to be polite about it, people say hairpiece, or in advertising hair system or hair replacement. English spells it toupée or toupee, both fine, and says it roughly "too-PAY". It is not a common word in daily talk — you meet it in jokes, in films, and in gossip about someone's hair looking different.
