What is the best type of flat iron for coarse, thick, naturally curly hair?

Thick, coarse, curly hair requires high heat for effective straightening. Look for an ionic ceramic flat iron that heats up to 450 degrees F. Hi-tech materials allow flat irons to reach high temperatures quickly for better, faster results with minimal damage. If your hair is also long, look for an iron with wide 2-inch or 2-1/2-inch plates. For best results, apply a heat protection spray before straightening.
