Where should a neutralizer be applied during a perm process and why?

The application of a neutralizer in the perm process is critical for ensuring that the new curl structure is effectively set and maintained. Applying the neutralizer both at the top and bottom of the curled hair ensures even saturation and distribution. This approach helps penetrate the entire hair shaft uniformly, which is essential for neutralizing the perm solution that alters the hair's internal structure.

When the neutralizer is spread thoroughly, it works to reform the disulfide bonds that were altered during the waving process, allowing the hair to hold the desired shape. Uniform application is key; if the product is only concentrated at one area, it may lead to inconsistencies in texture, curl formation, and potential damage to the hair.

Focusing on all parts of the hair with the neutralizer also mitigates issues such as uneven curls or unwanted frizz, resulting in a more polished and well-defined hairstyle. This practice ultimately supports hair integrity and longevity of the style, which is a fundamental concern in the barbering and cosmetology fields.
