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

The role of a neutralizer in the perm process is crucial for stabilizing the curl. After the hair has been permed using a waving solution, which alters the structure of the hair by breaking down disulfide bonds, the neutralizer restores these bonds but in a new shape, creating a lasting curl. It works by introducing a different chemical process that allows the reformation of these bonds around the perm rod's shape once the hair has been set.

While moisture is important for hair health and conditioning is essential for maintaining hair integrity, these functions are not the primary purpose of a neutralizer. The neutralizer specifically focuses on completing the perming process by ensuring the newly formed curl structure is stable, allowing the curl to maintain its shape. Hence, its primary function is to stabilize the curl after the permanent waving process.
