A flat iron, also known as a hair straightener, is a styling tool used to straighten or smooth hair. Flat irons can be used on all hair types, but they are particularly beneficial for natural hair, which is often curly, coily, or kinky. The best flat iron for natural hair will have features that are designed to protect the hair from heat damage, such as ceramic or tourmaline plates, adjustable heat settings, and ion technology.
Using a flat iron on natural hair can help to reduce frizz, smooth the hair shaft, and create a sleek, polished look. Flat irons can also be used to create curls or waves, depending on the technique used. However, it is important to use a flat iron on natural hair only occasionally, as excessive heat can damage the hair.
