Ionic hair dryers work by producing negative ions, which break down the positively charged water molecules in the hair, leading to faster drying and reduced frizz. They are designed to protect the hair from heat damage and enhance shine. One example of an ionic hair dryer is the SHRATE Ionic Hair Dryer, which uses negative ion technology to reduce moisture loss and damage to the hair due to overheating, and to protect the gloss of the hair. It also features a constant temperature of 134.6°F for hair care and low noise operation. Ionic hair dryers are known for preserving the definition of curly hair, drying the hair faster, and reducing frizz. However, it's important to note that it's easier to over-dry the hair with ionic hair dryers, which can be damaging, especially to fine hair. Additionally, ionic hair dryers can be more expensive than traditional and ceramic models
