What is the primary benefit of using a neutralizing solution after perming?

The primary benefit of using a neutralizing solution after perming is to set the curls. During the perming process, the hair's natural structure is altered through a chemical reaction that breaks and reformats the disulfide bonds in the hair. After the desired curl pattern is achieved through the application of the perm solution, the neutralizer is applied to lock those new bonds in place. This step is critical for ensuring that the curls maintain their shape and structure after the hair is rinsed and styled. The neutralizing solution also helps to restore the pH balance of the hair, contributing to the overall health and resilience of the hair post-treatment.

While moisturizing the hair can be beneficial for hair health, this is not the primary purpose of a neutralizing solution. Additionally, preventing frizz and enhancing hair color are also important aspects of hair care, but they are secondary to the crucial role that the neutralizing solution plays in securing the newly formed curl structure.
