Advantages of Negative Ion Hair Dryers
1. Care for hair. The negative ion hair dryer can avoid static electricity and make frizzy hair soft. Because of the built-in negative ion device and semiconductor refrigeration device, it can neutralize the positive and negative of the hair during operation, and generate water vapor to keep the hair hydrated.
2, the role of health care. Negative ions, also known as "longevity hormones", can strengthen the inhibitory effect of the cerebral cortex and help prevent brain diseases. In addition, negative ions can relax bronchial smooth muscle and relieve asthma symptoms. Negative ions are also said to be helpful in treating flu, rickets, scurvy, arthritis, and burns. Therefore, the negative ions have many effects, and the negative ion hair dryer naturally has a certain effect.

The principle of negative ion hair dryer
The principle is to install an air negative ion generator on the air outlet of an ordinary fan. It is a high-voltage electrostatic generator. Appropriate control of the voltage and current can make it generate negative air ions. The negatively charged particles and water molecules then encounter the hair and interact with the positive charge commonly found in hair, which smooths the frizz, smoothes the hair, and eliminates static electricity.
Tips for choosing a negative ion hair dryer
1. Consider security. When buying negative ion hair dryers, it is important to pay attention to its safety, because if leakage occurs during use, it will affect people's health. In general, only buy hair dryers with double insulation.
2. Consider power. Hair dryers are often used. If the power is too large, it means that the power consumption is also large. Therefore, in order to save electricity, when purchasing, try to choose a hair dryer with moderate power but large air output.
3. Consider quality. When purchasing, you should carefully check the quality of the product. If conditions permit, try it yourself, smell it for odor, listen for noise, and touch it to see if it has been used for a long time and whether the temperature is too high.
4. Consider the concentration of negative ions released. In general, the concentration of negative ions released by the negative ion hair dryer during operation can reach more than 6*107 per cubic meter, so that the hair can be quickly dried and supple.
