Acid waves that require heat from a dryer are called what?

• A. Endothermic waves
• B. Exothermic waves
• C. Cold waves
• D. Thermal waves

Answer: (A)

Endothermic waves describe acid waves that need heat to proceed. The dryer provides the energy required to activate the waving lotion, helping it soften the hair and break and reform the bonds so the curl sets properly. This is different from exothermic waves, which generate heat through the chemical reaction itself and don’t depend on external heat. Cold waves, on the other hand, are designed to process without added heat. The term thermal waves isn’t a standard one in practice.
