Editor Quote: "I found it easy to work in pretty large sections of hair — roughly two-inch pieces — and didn't experience any snags or knots. The Airstrait actually detangled hair in the process of drying it. My final result was silky-smooth hair with lots of shine that felt healthy (as opposed to fried)." — Jessica Harrington, senior beauty editor

Best Long-Lasting Flat Iron
GHD Duet Style ($339, originally $399)
This hair tool is a two-in-one dryer-straightener hybrid. It works similarly to the Dyson Airstrait in that you can use it on wet hair to save time styling and conserve precious storage. Unlike the Dyson, it does use heated styling plates, so that's a factor to consider when weighing the pros and cons. Nonetheless, it has its fair share of fans, one of whom is a POPSUGAR social producer. Learn more about her experience using it via her comprehensive review of the GHD Duet Style.
Editor Quote: "The most important thing for me in any styling product is the time-saving aspect. With the GHD Duet Style, not only can I go from sopping wet to styled hair in the time it takes to watch half an episode of "The Office," the results actually lasted. Even though the tool offers the shine shot functionality, which the brand advises using on second-day hair, I really didn't need it. My hair stayed stick-straight for at least two to three days after the initial use." — Chloe Dunn, social content producer
