In a chemical texture service, what process rehardens newly arranged disulfide bonds?

In a chemical texture service, the process that rehardens newly arranged disulfide bonds is the neutralizer. During services such as perming, the hair's disulfide bonds are altered through the use of a waving solution, which softens the hair and allows it to take on a new shape. After this process, the neutralizer is applied to the hair. The neutralizer works by restoring the disulfide bonds in their new configuration, effectively hardening them and ensuring that the new shape is maintained.

The role of the neutralizer is crucial because it stops the action of the waving solution and stabilizes the new shape of the hair. Without this step, the hair would be left in a weakened state, and the new curl or wave pattern would not hold. This validates the necessity of using a neutralizing agent in combination with the waving solution during a perm service or similar chemical texture treatment.
