what is negative ion
Negative ions are a kind of fine particles, which are composed of negatively charged oxygen and small water molecules in the air, which can be simply understood as negatively charged particles. It can effectively combine the moisture and oxygen in the air, and the negative ions will absorb the hair during the blowing process, so that it can penetrate into our hair core, and form a protective layer on the surface, which can lock the moisture.
A negative ion generator is installed inside the hair dryer. When the wind is blowing, the generator works and releases a large amount of negative ions. The negative ions attach to the surface of the hair and neutralize the electric ions generated by blowing the hair, so that the hair will not be so static and frizzy. Therefore, the negative ion hair dryer can effectively smooth the frizz and dryness, and make the hair smooth and docile. However, the neutralization of static electricity by negative ions is instant, and the smoothing effect is time-consuming, and it cannot improve hair quality.
Negative ions neutralize static electricity immediately, and the smoothing effect takes time, and does not improve hair quality. Because, the hair will generate new static electricity anytime and anywhere. In winter, hair is prone to static electricity, and negative ions are needed to eliminate static electricity and make hair smooth.
