What is the purpose of a neutralizer in the perming process?

The purpose of a neutralizer in the perming process is to stop the chemical reaction that occurs during the curling process and to effectively lock the curls in place. When hair is permed, it goes through a chemical change facilitated by the perm solution, which breaks down the hair's disulfide bonds. After the desired curl is achieved, the neutralizer is applied. Its role is crucial; it acts to re-establish the disulfide bonds and stabilize the new curl pattern that has been created. This means that the curls will hold their shape and remain intact after the processing time, ensuring the success and longevity of the perm.

While neutralizers can impact the overall condition of the hair, the primary focus remains on the cessation of the chemical reaction and the setting of the curls. Other options such as enhancing fragrance, conditioning, or clarifying the hair do not accurately reflect the core role of a neutralizer in the perming process. Therefore, the essence of using a neutralizer lies in its vital function to secure the new curl structure formed within the hair.
