Fine hair usually takes a curl at lower heat than thick hair, so the most useful thing a curling iron can offer is a real low end on its temperature range. The catch is that most listings state the top temperature and stay quiet about the bottom. This guide shows the lowest temperature only where the listing actually gives one, and marks the rest Not stated, so you know which tools you would need to check. Barrel size matters as well: fine hair tends to drop a large loose curl quickly, so 1 inch barrels and smaller give tighter curls that have more to lose before they fall flat. This guide compares seven tools from Bio Ionic, T3 and ghd by barrel size, number of heat settings, lowest stated temperature, maximum temperature and clip or wand design.
