When it comes to hair, Byrne knows exactly which tools work for her. “I love the Harry Josh Pro Tools hair dryer,” she says, calling it “the best hairdryer on the market. It does my hair, which is wild and uncontrollable, in ten minutes.” While it’s a heftier price tag than many hair dryers, Byrne promises it’s “worth it.” The brand says this heat tool can reduce drying time by up to 50 percent, and the dryer itself is lightweight and easy to use. “It’s brilliant… and a really good investment,” Byrne adds.
