What is the primary benefit of using a neutralizer after a perm?

The primary benefit of using a neutralizer after a perm is that it stops the perming process and reforms the hair bonds. During the perming process, a chemical solution is applied to break down the disulfide bonds in the hair, allowing it to be reshaped into curls or waves. Once the desired shape is achieved, a neutralizer is applied to restore and reform these bonds in their new configuration, effectively locking in the new style.

Neutralizers play an essential role in ensuring the longevity and integrity of the curls or waves created by the perm. They work by introducing a different set of chemicals that bond with the hair structure, stabilizing it in its new form. Therefore, this step is crucial in achieving lasting results and preventing the curls from reverting to their original straight form.

While other options may refer to benefits associated with hair treatments, they do not directly pertain to the primary function of a neutralizer in the perming process. For instance, adding volume or enhancing color may be advantages of different hair treatments, and ease of styling could be an indirect effect, but they are not the focal purpose of using a neutralizer after a perm.
