Hair straighteners, also called flat irons, have increasingly become more and more popular as women are looking for no frizz, sleek hairstyles. The increased technological advances in these tools including ceramic plating and better design have boosted the use of hair straighteners. Hair straighteners allow straightening of hair at home without the need to go to the salon for chemical treatments or other expensive methods. Because of different plate sizes, hair straighteners can be used on many different hair types as well. These tools will continually become more popular. Popular brands now include Sedu, Solia, and CHI.
