L'oreal should really market this as a combination appetite suppressant and hairspray. It smells so horrid, and yes, the smell clings to (the room you sprayed it in, your hair) so that as you move throughout the day, more will release from your hair. Yes, it does get subdued after a few hours. I am thankful I only bought the trial version, which I pitched after trying it a few times and feeling nauseated each time. This does work to create some fullness and bouncy hair, but the smell is terrible!
