When Carolyn Aronson set out to simplify our haircare routines, she traded her scissors for bottles – and built an empire.  Her best-selling It’s a 10 Miracle Leave-In Spray sells over 14 million bottles a year, and the Be a 10 haircare line has grown to address curly hair, limp hair, and of course, this Florida native has a line for frizz-free hair that includes a spray that will literally waterproof your hair.
