While tourmaline makes it easier to reach the needed effect on coarse and curly hair, ceramic plates work great against frizz as they seal moisture inside the hair. This effect is similar to tourmaline plates, but it’s weaker. The material is still a versatile solution for healthy cuticle and shine, but it’s not likely to deal with wild hair types. If you need a flat iron for frequent commercial use, it’s important to understand that many ceramic models have metal plates coated in ceramics. This solution is generally good due to quick and even heat distribution, but it’s also prone to quick ceramic layer erasure.
