Which of the following actions is not a step involved in curl reforming?

In the context of curl reforming, the process involves several key steps that are specific to altering the structure of the hair's curl pattern. These steps include reduction, reforming, and rebonding.

Reduction refers to the breaking down of the disulfide bonds in the hair, allowing the hair to change shape. Reforming follows, where the hair is put into a new curl pattern, and then rebonding occurs, which is the reformation of those bonds to set the new shape.

Restraightening, on the other hand, is not a part of the curl reforming process. Instead, it is an action typically associated with relaxing, where curls are smoothed out rather than restructured. Understanding the distinct differences between these processes is critical in effectively applying techniques tailored for desired hair transformations.
