Ionic technology as it relates to hair care, whether it is a hair dryer or a straightening tool, indicates how the tool works on hair. Hair tools labeled as ionic produce negative ions that counteract positive ions.
The benefits of using ionic flat irons include moisture removal, smoother and less frizzy hair, and less damage to the hair. Ionic flat irons help keep the cuticle layer of the hair protected, which produces smooth, straight hair with zero frizz and high shine. There are ionic flat irons available from a variety of companies with several options in reference to the type of plate used.
