Question about tiaras

If you get the kind with the comb make sure the comb is metal. My hairdresser told me that the metal comb stays in better and when taking it out it dosen't cause knots. I had my viel on a plastic comb and I ripped it off and reglued it onto a metal one. It slid right our of my head and didn't take one hair out of place. I danced my bootay off all night long and not once did my tiara move from it's spot.
