Which processing method is described as 'self heating'?

Endothermic
Exothermic
Alkaline Wave
Acid Wave

The correct answer is: Exothermic

Exothermic processing method is described as 'self heating'. This is because exothermic reactions release heat, causing the temperature of the surrounding environment to increase. Option A, Endothermic, describes a processing method that absorbs heat, resulting in a decrease in temperature. Option C, Alkaline Wave, and option D, Acid Wave, both refer to specific types of permanent wave processes and do not pertain to self heating. Therefore, these options are incorrect.
