Question: 1 / 400

What does the term "endothermic" refer to in the context of chemical relaxers?

A chemical reaction that cools the product down

A chemical reaction that requires heat to activate the product

The term "endothermic" in the context of chemical relaxers refers to a chemical reaction that requires heat to activate the product. In endothermic reactions, the system absorbs heat from the surroundings, which is crucial for the reaction to proceed effectively. In the case of chemical relaxers, the heat may come from the environment or from the application of heat sources such as a hooded dryer. This heat is essential for the relaxer to soften and alter the hair's structure effectively, allowing it to straighten.

Understanding the role of heat in endothermic reactions helps in effectively applying chemical relaxers, as temperature can significantly influence the outcome of the treatment. Proper heat application ensures that the relaxer works optimally and reduces the risk of hair damage by allowing the chemical process to occur as intended.
