What is a Negative Ion and what does it do for my hair?

A negative ion is an invisible particle with an electric charge. Negative ions when ingested have health benefits and have moisturizing qualities. When your tool is heated, negative ions are created to seal and prevent further damage to the hair cuticle. The negative ions cancel out the positive hair charges, and while the iron makes contact with your hair, you smooth those ragged open cuticles.
