a. Using a simple treatment with electric plates consisting of two hot plates (at a temperature higher than 100°C). The hair is placed between the two plates and compressed to achieve the desired style.
b. Chemical treatment combined with low-temperature mechanical processing: A chemical substance is applied to the hair, which causes a change in the hair when treated at a temperature below 100°C.
c. Chemical treatment combined with high-temperature mechanical processing: A chemical substance is applied to the hair and treated at a temperature higher than 100°C. Due to the combination of heat and the chemical substance applied to the hair, this technique can cause more significant changes in the hair than those achieved by other techniques.
