THE CLAIM Usually defrizzers rely on silicones (molecules that instantly smooth hair but can make it dull and dry over time). L'Oréal's tamer uses natural oils to seal the cuticle.
THE EXPERT SAYS "This product contains little natural oil," says Wilson. "It is, however, smoothing the cuticle with a natural fixative similar to those used in hairsprays and then keeping strands soft with a hefty dose of glycerin."
OUR VERDICT After testing nearly every anti-frizz potion, we found that this leaves our hair smoother than almost anything else on the market.
