Winner: Avon Advance Techniques Frizz Control Lotus Shield
Many smoothing serums get the job done, but the trade-off is lank, greasy-looking strands that start to frizz up again in a few hours. That's why our testers were so blown away by Avon Lotus Shield. It forms a lightweight humidity-resistant barrier on the hair's surface that locks out moisture and eliminates puffiness without feeling slick for up to three days.
