Before you buy: 3 quick checks

Barrel size decides the look.

Pick a barrel size

1 inch is the most versatile and works on most lengths. Smaller barrels (3/4 inch) make tight curls. Bigger ones (1.25 to 1.5 inches) make loose waves and work best on long hair.

Match the heat to your hair

Fine or damaged hair needs lower heat. Thick or coarse hair can take more. Always use heat protectant first.

Stay safe

Curling irons can burn skin quickly. A heat-resistant glove helps, especially for beginners. Rest it on a heat-safe mat and unplug it when you're done.
