phony-tail

A woman's ponytail that is entirely made up of weave or extensions.

Everyone can tell that's a phony-tail she's sporting. Yesterday she was damn near bald headed.

Phony Tail

When a balding man, pretends to have enough hair to pull back into a pony tail.

That guy is practically bald but he's got the four strands on the back of his head pulled back into a phony tail.
