What is the role of the neutralizer in the perming process?

The role of the neutralizer in the perming process is crucial for effectively completing the chemical transformation of the hair. After the waving solution breaks the disulfide bonds in the hair, the neutralizer works to re-form these bonds in their new shape, solidifying the curls that have been created. This step is vital because, without the neutralizer, the hair would not retain the perm's shape, potentially leading to a loss of the desired curls.

The neutralizing agent typically also helps to restore the hair's natural pH balance after the hair has been chemically altered. This process assists in locking in the curls and ensures the longevity and stability of the perm. In the context of perm application, it is not related to enhancing curls, cleaning the hair, or adding shine, but rather serves specifically to finalize the perm by strengthening the new structure of the hair.
