What is the primary purpose of using a neutralizer in a relaxer treatment?

The primary purpose of using a neutralizer in a relaxer treatment is to stop the chemical process and restore pH balance. During a relaxer treatment, the chemical relaxant alters the hair's natural curl structure by breaking down the disulfide bonds. Once the desired level of straightness is achieved, the neutralizer is applied to halt this chemical action.

Neutralizers often contain ingredients that help to stabilize the hair's pH, which is critical because relaxers typically raise the hair's pH to facilitate the lifting of the cuticle and the alteration of the hair’s internal structure. By restoring the pH balance to a more neutral level, the neutralizer aids in forming new bonds, effectively locking in the new straight configuration of the hair. This process not only ensures that the effects of the relaxer last longer but also helps to maintain the hair's overall health, reducing the risk of damage that can occur if the chemical process is left unchecked.
