Ammonia-free waves are NOT characterized by what?

Rapid Evaporation
Strong Odor
Mild Application
Quick Processing

The correct answer is: Rapid Evaporation

Ammonia-free waves are characterized by a mild application and quick processing, making the experience more pleasant and faster than ammonia waves. Strong odors, which are found in ammonia waves, can be off-putting and linger even after processing. Ammonia waves also tend to have a rapid evaporation due to the harsher chemicals, whereas ammonia-free waves are more gentle and do not evaporate as quickly. Therefore, rapid evaporation is not a characteristic of ammonia-free waves.
