Classification of curlers
1) The curler can be divided into three types according to the different heating elements, namely ceramic heating element, PTC heating element and heating wire heating element.
The advantages of ceramic heating element are environmental protection, fast heating speed, which can reach 200 ℃ in 1.5 minutes, but the disadvantage is that the overall cost of using ceramic heating element curler is about 30% higher than PTC or heating wire.
2) According to the different styles of curling, it can be divided into straight stick and vertebral stick.
Straight stick, that is to say, the diameter of curling stick is the same from top to bottom, and the pattern of upper and lower curling hair is the same as that of curling hair. The cone-shaped curler can curl the hair into waves of different sizes. The hair roll can be from small to large, or from large to small, and the hair style changes a lot.
3) According to the usage, it can be divided into three categories: manual curler, semi-automatic curler and automatic curler. (see attached figure)
4) Precautions for using the curler: because the hot parts of the curler are exposed, if you curl your hair at home, others should help you curl your hair and try to avoid curling your hair. If you are not careful, it is easy to cause burns. If you operate it by yourself, you must choose the curler with clip, and the curler without clip is not easy to operate by yourself.
Clamp the hair tail with a clip, slowly roll it to the hair root, stay for 20 seconds, then release it, and the hair roll can be formed. Too long time will damage the hair quality. The use of automatic hair curler can avoid scalding. The shell temperature of automatic hair curler is generally not more than 60 degrees, and the heat dissipation is timely, and the handle temperature is lower. But pay attention to the roll to the hair.
