Choose according to your hair quality. If the hair is dry, you can choose a water ion hair dryer. The negative ion blower is equipped with a negative ion generator and a semiconductor refrigeration device, which can generate negatively charged ion particles and water vapor particles when working, and can neutralize the common positive charges in hair. Therefore, the negative ion hair dryer can smooth messy hair and make it smoother.
In contrast, ordinary hair dryers only generate heat to dry and wet hair when working, which is more likely to generate static electricity, and then lead to hair deformation or warping. From another point of view, ordinary hair dryers emit large radiation, which will have a certain impact on human health, while negative ion hair dryers will not emit electromagnetic radiation harmful to health and can be used for a long time.
