During the chemical waving process, which of the following is essential for creating curls?

The essential component for creating curls during the chemical waving process is the perm solution. This solution contains chemical agents, typically ammonium thioglycolate or glyceryl monothioglycolate, that break down the disulfide bonds in the hair's keratin structure. By altering these bonds, the hair can be reshaped into curls when wrapped around perm rods.

Without the perm solution, the hair would not undergo the necessary transformation to achieve the desired curl pattern. The process involves applying the perm solution first, allowing it to penetrate the hair shaft, and then shaping the hair around a rod. Once the desired curl is achieved, a neutralizer is used afterward to fix the new shape by reforming the disulfide bonds in their new configuration.

In contrast, base lotion is used to protect the scalp and hair from potential irritation during the chemical process, while a moisturizer helps maintain hair health during treatments but does not actually create curls. Thus, the perm solution is the key agent in the chemical waving process for curl formation.
