They emit negative ions. Water on the hair is made of positive ions. Negative ions will divide water molecules into smaller particles. The result is faster evaporation and less heat damage to the hair.
Other Benefits:
- Less static electricity which is generated by positive ions reacting to heat from conventional dryers.
- The negative ions will enhance the effect of the styling products on your hair for better results.
- The negative ions will help close the cuticles, which will retain moisture in the hair and adds shine.
Ceramic and Tourmaline
The added element of ceramic to hair dryers allows stronger heat retention and increases even redistribution. As for tourmaline, the negative ions of this mineral further increase heat and control static electricity.
