# Best flat irons for fine and thin hair Source: https://plateandwand.com/best/best-flat-iron-for-fine-hair Publisher: Plate & Wand. Picks are chosen from what each Amazon listing states, not from hands-on tests. Method: https://plateandwand.com/how-we-pick Fine and thin hair usually styles at lower heat than thick hair, so the most useful thing a flat iron can offer is control. That means either a dial with real low settings or a moderate fixed temperature, plus plates narrow enough to work small sections. The catch is that most premium listings state the top temperature but not the lowest one. We list the lowest setting where the listing gives it and write Not stated where it does not, so you know what to check. This guide compares seven irons on plate width, the number of heat settings, the maximum temperature, the lowest stated setting and voltage. Irons with many settings come first because they let you start low, followed by fixed-temperature ghd stylers that skip the dial entirely. ## Picks ### 1.
