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

The neutralizer plays a critical role in the perm process by stabilizing and restructuring the hair's bonds after they have been altered by the chemical waving solution. During the perming process, the solution breaks down the disulfide bonds in the hair’s cortex, allowing the hair to be shaped into curls or waves. Once the desired curl pattern is achieved, the neutralizer is applied. This solution works by causing the disulfide bonds to reform and stabilize into their new shape, effectively locking in the curls or waves.

Neutralizers also typically contain ingredients that help to reinforce and protect the hair structure, ensuring that the new curl or wave pattern remains intact over time. Their effectiveness is vital to achieving a successful and long-lasting perm, as it prevents the hair from reverting to its original state and helps maintain the health and integrity of the hair throughout the process.
