# Best flat irons for every hair type, compared by plate and heat Source: https://plateandwand.com/best/best-flat-iron Publisher: Plate & Wand. Picks are chosen from what each Amazon listing states, not from hands-on tests. Method: https://plateandwand.com/how-we-pick Premium flat irons split into two camps. Some, like ghd, lock the plates at one temperature so there is no dial to set. Others, like BaBylissPRO, T3 and Bio Ionic, give you a range of heat settings and a higher top temperature. Neither is better for everyone. Fine hair rarely needs the top of a 450°F range, while thick or coarse hair often benefits from it. Plate width matters too: 1 inch plates handle short hair, bangs and curls, while 2 inch plates cover long or thick hair in fewer sections. This guide compares seven irons from ghd, T3, BaBylissPRO, Bio Ionic and Dyson using only what each Amazon listing states: plate width, heat settings, maximum temperature, plate material and voltage. Where a listing does not say, the table says Not stated. ## Picks ### 1.
