2, the choice of curling iron.
(1) Products with official manufacturers and registered trademarks must be selected. It is recommended not to buy products that do not clearly indicate the manufacturer's address, certification mark and trademark on the packaging box, which belongs to the three-no products and the quality is not guaranteed.
(2) Look carefully at the technical specifications in the manual. Regular manufacturers will generally indicate the heating materials used. If the heating material is not marked, it is impossible to judge what the heating body is. You'd better buy a ceramic radiator. It is characterized by uniform heating, safety and certain infrared ray, which is beneficial to human body and hair.
(3) The surface of curling iron is generally sprayed with ceramic glaze, and the quality of ceramic glaze determines the effect of curling iron and the service life of the surface. A good ceramic surface is very smooth and has no astringency. The other surface is electroplated, and the adhesion is not as good as that of spraying ceramic glaze, which is not recommended.
