What is Acid Wave also known as?

1. Cold waves

2. Heat waves

3. Neutral waves

4. Flame waves

The correct answer is: Heat waves

Acid Waves are commonly known as "Cold Waves." This method of perming utilizes a balanced pH formula, which allows for the use of a relatively low temperature to achieve the desired curl. The term "Cold Waves" refers to the fact that they do not require the application of heat for the chemical process to take place, as the waving solution is sufficient to alter the hair's structure. This low pH formula results in less damage to the hair compared to other methods, making it a preferable choice for many stylists working with fragile or previously processed hair. It’s important to understand this terminology within the context of hair perming techniques, as it ties directly to the chemical processes involved and the care considerations necessary for clients.
