No, says Ziani. "Today’s formulas are better because the spray cans are regulated and use propellants such as hydrocarbons and compressed gases like nitrous oxide that do not deplete the ozone layer, a smart move for beauty in anyone's book." There are plenty of hold levels to choose from, but Mouzakis says that, as a general rule of thumb, going for more flexible holds is key. He suggests reserving super strong or firm formulas for updos only. Otherwise, “use a lower hold so your hair will still move naturally while still holding your style,” he says. Plus, many of these formulas are also buildable, so you can easily add another layer if you want even more hold. Great examples of flexible hold formulas are the Unite Lé:Play Hair Spray and the Kérastase Laque Couture Medium Hold Hairspray Alcohol-Free Formula John Mouzakis is a stylist and co-owner of 3rd Coast Salon in Chicago.
