Which product is commonly used for neutralizing perms?

The commonly used product for neutralizing perms is an acid-based neutralizer. This type of neutralizer works by restoring the natural pH of the hair after the alkaline perm solution has opened the hair cuticle and altered the hair’s structure.

During the perm process, the hair is subjected to chemicals that break the disulfide bonds in the hair’s cortex, allowing it to be reshaped into curls. Once the desired style is achieved, it is crucial to halt the chemical action and set the new shape. An acid-based neutralizer helps to close the hair cuticle and re-establish the bonds, solidifying the new curl structure in place. It typically contains ingredients that help in this crucial process, ensuring the hair maintains its new shape while reducing damage.

Conditioners, hydrogen peroxide, and moisturizers do not serve the specific role needed for neutralizing perms. While conditioners and moisturizers may contribute to overall hair health and hydration, they do not actively neutralize the perm solution. Hydrogen peroxide is a strong oxidizing agent that can be too harsh and disruptive for the hair in this context and is not intended for neutralizing perms effectively.
