When you use it, especially for girls, don't blow it in one place all the time. Because the power of some hair dryers is relatively high, the hair will be burnt if they are blown in one place all the time. Do not use the hair dryer to dry the clothes, which will cause the tuyere to melt. The hair dryer must not be used for too long. Girls must pay attention not to put the back of the hair dryer too close to the hair. Or you'll suck your hair in. This kind of situation is mainly aimed at the mesh mouth behind the air blowing.
