Thick and coarse hair asks two things of a flat iron: enough plate area to take a real section at once, and enough heat control to get through it. Plate width is the first filter. A 1.5 inch or 2 inch plate grips more hair per pass than a standard 1 inch iron, which matters most on long, dense hair. The second filter is heat. ghd irons hold a fixed 365°F and rely on plate design, while BaBylissPRO, T3 and Bio Ionic let you choose the setting, with listed tops of 450°F to 465°F. This guide compares seven irons over $150 with 1.5 or 2 inch plates. For each one we list plate width, top temperature, number of heat settings, voltage and cord as the Amazon listing states them. Where a listing is silent, the table says Not stated so you know what to check before buying.
