# Best flat irons for natural, curly and coily hair Source: https://plateandwand.com/best/best-flat-iron-for-natural-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 A silk press on natural, curly or coily hair asks more of a flat iron than a quick touch-up on straight hair. Dense, tightly curled sections often need more heat and a smooth plate that glides without snagging, while thinner sections around the hairline need less. That is why adjustable temperature matters here: an iron that only offers one preset may be too cool for some textures, and one that only runs hot gives you no room to go lower. Plate width matters too. A 1 inch plate gets closer to the root on small sections, while 1.5 to 2 inch plates move through long, thick hair faster. This guide compares seven irons by plate width, number of heat settings, maximum temperature, plate material and voltage, using only what each Amazon listing states. ## Picks ### 1.
