The temperature difference is tested between a real person with healthy hair and a real person (partially damaged hair) with a temperature measuring gun: at a fixed distance of 5 cm, 10 cm and 15 cm, measure the surface of the hair at intervals of 10 seconds In the heating condition, the higher the temperature, the greater the damage to the hair. On average, this The three hair dryers have their own characteristics.

The lower the number, the lower the noise value. If it is actually blown to the hair, the heat will continue to increase if the same place is blown. The concentration of negative ions and ozone is not currently relevant in law. People who have more hair, longer and thicker hair or need to style at the same time can use these small assistive devices. The ozone generation situation is not the same for each model, so there will be a strange smell when blowing.

Moreover, the wind temperature of the hair dryer is very high, even if water anions are produced, it will be quickly evaporated by high temperature, so the application of this technology to the hair dryer has limited practical significance for hair care. Once the distance is too close, the temperature can exceed 70°C for about 10 seconds. A more advanced approach should be that the hair dryer can detect the temperature and automatically adjust it so that the temperature of the hair and scalp can be controlled within the range of 50 degrees C plus or minus 5 degrees C.

Individually adjust the hair dryer to the maximum blowing temperature and maximum air volume test data chart as follows: (1) Film test part (2) Live test part There are a few key points to share with you: A. Such claims really can only be seen. The temperature rises to 75 degrees C, the same time distance 10 cm will heat up to 65 degrees C; 15 cm is 60 degrees C. As for the protective film to protect the hair, make the hair better and brighter, increase the moisture retention of the hair, less damage the hair, let the hair dry faster, and let the hair resist ultraviolet rays. Of the three machines tested, only PHILIPS has such a design.For me, curling iron I think the most important reference indicators are temperature and noise.

As for the body temperature, the body temperature is mostly heat-resistant materials before and after use. This approach can also reduce the heat damage to the hair and scalp. If you are interested, you can also test it yourself, hoping to give you a more scientific basis for selection. 15 cm is about the distance from the tip of the thumb to the tip of the little finger when the palm is opened
