How Ionic Technology Works: The Science Explained
Ionic hair straighteners emit negative ions that break water molecules on hair shafts. This process seals cuticles and locks in moisture, unlike conventional straighteners that simply flatten hair with heat. The result? Up to 89% less frizz according to Journal of Cosmetic Science studies.
