The term "exothermic" in the context of a perm solution refers to a chemical reaction that generates heat. This occurs during the process where the perming solution interacts with the hair's protein structure. As the solution breaks down the disulfide bonds in the hair, it releases heat, which can enhance the effectiveness of the perming process and help in reshaping the hair.

Understanding exothermic reactions is essential for cosmetologists because it explains why certain perm solutions may heat up during application. This heat can aid in the curling process, ensuring that the hair takes on and retains the new shape effectively. Recognizing this reaction enables professionals to apply these products safely and achieve desired results while being aware of any potential risks associated with heat production.

The other options do not accurately describe the term. Exothermic does not refer to a process requiring external heat, a type of hair damage, or a cooling method used in perming, as it specifically relates to the generation of heat during a chemical reaction rather than external influences or negative outcomes.
