In the context of perms, what is the role of a neutralizer?

The role of a neutralizer in the context of perms is crucial as it serves to stop the chemical process initiated by the perm solution and lock in the desired curls or waves. When hair is permed, it undergoes a chemical transformation that alters its structure, making it necessary to use a neutralizer to halt this transformation at the right moment. The neutralizer works by restoring the pH balance of the hair and re-bonding the hair fibers, thus ensuring that the new curl pattern is set and remains intact. This step is essential for the longevity and effectiveness of the perm, as it solidifies the shape created by the perming solution. Therefore, its role goes beyond simply adjusting the aesthetic qualities, focusing instead on securing the permanent change in the hair’s structure.
