All of the following are procedures involved in the chemical phase of perms EXCEPT:

The procedure that is not involved in the chemical phase of perms is wrapping hair around the perm rod. This step, while crucial to the overall perming process, falls under the physical phase rather than the chemical phase. The wrapping step focuses on how the hair is shaped and arranged around the rod, which affects the overall curl pattern but does not alter the hair structure chemically.

In contrast, the chemical phase involves actions that affect the hair's internal structure through the application of chemicals. Applying the perm solution introduces ingredients that break down the disulfide bonds in the hair, allowing it to adopt a new shape once it is wrapped. Applying neutralizer is also part of the chemical phase, as it helps to reform the disulfide bonds in their new configuration after the perm solution has processed. Rinsing the perm solution from the hair is essential to stop the chemical process and ensures that the hair is not over-processed. Therefore, wrapping hair around the perm rod is the only procedure mentioned that does not involve any chemical action.
