What does perm neutralizer do?

A perm neutralizer is a chemical solution used in the perming process to stop the action of the perming solution and set the new curl pattern in hair. It helps to restore the hair's pH balance after the perming process, ensuring that the curls hold their shape and remain stable. Additionally, it conditions the hair, helping to reduce damage and enhance shine. By neutralizing the chemicals, it also helps to prevent any further chemical reactions that could harm the hair.
