# Best hair straighteners: plates, cordless and hot air Source: https://plateandwand.com/best/best-hair-straightener Publisher: Plate & Wand. Picks are chosen from what each Amazon listing states, not from hands-on tests. Method: https://plateandwand.com/how-we-pick There are now three ways to straighten at home, and picking the type first makes the model choice easy. Classic flat irons press hair between heated plates and work on dry hair. The Dyson Corrale uses flexing plates and can run without a cord. Hot air tools like the Dyson Airstrait and the ghd Duet Style straighten while they dry, so they start on wet hair. A good pick matches how you style: a fixed-temperature iron suits someone who wants no settings, an adjustable iron suits coarse or mixed textures, and an air tool suits people who want to skip the separate blow dry. This guide compares seven straighteners over $150 by type, plate width, top temperature, number of heat settings, voltage and power source. Every spec comes from the Amazon listing, and anything the listing leaves out is marked Not stated. ## Picks ### 1.
