Need a physics refresher? An ion is an atomic particle that is looking to either gain or lose an electron in order to achieve molecular stability. It does this by attaching itself to the nearest, oppositely charged ion.
Negatively charged ions are found in many haircare products and tools today because of their ability to bond with and change the structure of the molecules they come in contact with. By breaking down water molecules into smaller bits, they allow hair to dry in a fraction of the time. Ions are also starting to be used in some haircare lines because of their ability to soften and open up the hair cuticle, allowing it to absorb more moisture.
