What is the primary benefit of using a neutralizer in hair treatments?

The primary benefit of using a neutralizer in hair treatments is to stop chemical reactions. When a chemical treatment, such as a perm or relaxer, is applied to the hair, the process involves altering the hair's structure. A neutralizer works by halting these chemical reactions, effectively setting the new shape or texture of the hair and ensuring that the effects of the treatment are stabilized. This is crucial for preventing further changes that could damage the hair or result in undesirable outcomes.

In the context of hair treatments, a neutralizer ensures that the hair does not revert to its original form after the treatment has been applied. It also helps to close the cuticle, which can improve the overall appearance of the hair.
