Not sure what to choose between the best curling iron and a classic flat iron? It is true that flat irons look more functional because they straighten hair, but they also give you curls. There is one condition though – plates must be really narrow. But then, you have to consider your necessities. Do you want some basic curls or perhaps some waves? If you are interested in a professional result and you truly care about your curls, then buy the real thing – a curling iron. These things are specifically built to give you strong and durable curls of all sizes.
