What component is included in all acid waves alongside the waving lotion and neutralizer?

Activator
Heat Source
Conditioner
Rinse

The correct answer is: Activator

The inclusion of an activator in all acid waves is essential for enhancing the effectiveness of the waving lotion. Acid waves use a lower pH than alkaline waves, which results in a gentler perm process. The activator helps to increase the efficiency of the waving lotion by adjusting the formula so that it can penetrate the hair cuticle more effectively. This allows for more controlled and consistent curls while minimizing damage, making it a crucial component in the perming process. In comparison, the other components mentioned do not serve the same fundamental role. A heat source might be utilized in certain perming processes, but it isn’t a universal requirement for all acid waves. Conditioner can be an important part of hair care post-treatment, but it isn't included in the actual waving process. Similarly, a rinse may follow after the waving procedure, but it is not a standard component that is mixed with the waving lotion and neutralizer. Therefore, the activator is the key component that aids in achieving desired outcomes in acid waves.
