12 Hairstylist-Approved Products For (Finally!) Fighting Frizz

"I cannot live without this product in my kit. I love using it for red carpet to prevent flyaways and frizz. It's especially great on curly hair. It puts a lightweight barrier around the hair, and moisture can't get in. I like to have my clients toss their head upside down while I spray it all over. That way I get the underneath of the hair and close to the neck where it can get hotter, and holds humidity." — Ristaino
