Hair stylers, also known as hair straighteners or flat irons, are hair care tools that are used to style hair. They are typically heated and have smooth, flat plates that are used to straighten, curl, or add waves to the hair. Hair stylers can be made from a variety of materials, including ceramic, titanium, and tourmaline, and come in a range of sizes and shapes to suit different hair types and styles. Some hair stylers may also have additional features, such as adjustable heat settings and built-in safety features, to help create the perfect hairstyle.
