In addition, some manufacturers claim that hair dryers produce ‘mineral ions’ that can help hair sunscreen, but there is no literature on the relationship between mineral ions and hair sunscreen, and there is no indication of the degree of sun protection. Too close can cause the temperature to rise too fast and high and damage the hair. In addition, the hair dryer often comes with a blower nozzle and a drying hood.

The possible disadvantage of negative ion hair dryers is that ozone is generated during the negative ion generation process. It took a month to test and find information and write articles. Simply put, ‘negative ions are negatively charged ions. Since the hair itself is negatively charged, it is easy to attract positively charged dirt materials, so the shampoo will use anionic surfactants to wash away the dirt. At this time, if the negative ions blown by the hair dryer are adsorbed on the hair, it will make the hair more negatively charged and make the hair less tangled and tangled for easy combing.

Taking TESCOM as an example, it can be seen in the real-person test data that the temperature will rise to 80 degrees C at a distance of 5 cm; 70 degrees C at 10 cm; 65 degrees C at 15 cm; at a distance of 5 cm, the temperature will rise in 10 seconds. This part of the meaning is relatively small, because the negative ion generator of the hair dryer can only use the water vapor in the air to generate water negative ions. There are also manufacturers claiming that hair dryers can blow out collagen for hair care, but the hair itself is composed of keratin instead of collagen. . Therefore, it can be seen that the greater the power, the greater the noise.

What are the benefits of such temperature control? In addition to protecting the hair and scalp from overheating and causing burns, whether it is damaged hair, thin hair, sensitive scalp, Electric Ionic Brushes Manufacturers or people who are prone to hair loss, even children, the elderly, diabetes, and neuropathy patients will feel more at ease. In terms of temperature control, low dryness and value, PHILIPS completely wins. I use a noise meter to measure the noise level at the front, top, side, and back of the body 15 cm at the maximum wind speed, as well as the position directly behind the body motor (see the table below). Looking at the above results, we can indeed use a more rational thinking to buy hair dryers.
