Fall Beauty 2009

THE PRODUCT Kerastase Volumorphose, an in-salon hair treatment ($35; visit kerastase-usa.com for salon locations).
THE PROMISE Instant body and thickness that lasts a few days and prolongs a professional blowout.
THE EXPERT SAYS "This could potentially be very effective," says chemist Jim Hammer. "It has a molecule that bonds to the hair's surface, and when moisture is applied—whammo! The molecules link to form a three-dimensional polymer, which has thickening effects and promotes volume."
WE SAY Our hair definitely had more oomph, and the blowout lasted an extra day.
