Flat irons can consist of two flat plates that include ceramic or what other material?

Flat irons are commonly made with two flat plates, which can be constructed from different materials to affect their performance and usability. One of the popular materials, alongside ceramic, is metal. Metal plates can provide even heating and excellent heat conductivity, which allows for effective styling. They can reach high temperatures quickly, making them suitable for various hair types, especially those that require higher heat for effective straightening.

When metal is used in flat irons, it often complements the ceramic coating, enhancing the durability and effectiveness of the tool. This combination can lead to a smoother glide through the hair, helping to reduce frizz and promote a shiny finish.

Ceramic plates are well-known for their ability to distribute heat evenly and to minimize damage to the hair. Therefore, metal works as an alternative that also offers beneficial qualities for hairstyling. Other materials like glass or plastic do not possess the same thermal conductivity and durability required for efficient styling tools, which is why they are not the correct answer in this context.
