Sunan an-Nasa'i Book 48, Hadith 54
"I saw Mu'awiyah bin Abi Sufyan on the Minbar, holding a ball of hair such as women use. He said: "What is wrong with Muslim women who put such things (on their heads)? I heard the Messenger of Allah say: "Any woman who adds hair to her head that is not hers, it is something false, that she is adding to her head."
