What is the purpose of a neutralizer in a chemical service?

The purpose of a neutralizer in a chemical service is primarily to stop the action of the waving solution. In the context of processes like perming, a waving solution is used to break down the hair's disulfide bonds, allowing it to be reshaped. Once the desired curl or wave has been achieved, the neutralizer is applied to halt this chemical process. It works by reforming the disulfide bonds, effectively locking the new shape in place. This is crucial for ensuring that the hairstyle holds and maintains its structure over time.

In chemical services, simply halting the action of the waving solution is vital to ensure that the hair does not become over-processed or damaged. The neutralizing step is fundamental for the integrity of the curl and the overall health of the hair after the treatment.
