New Jersey Cosmetology State Board Practice Exam 2026 – Complete Prep Guide

Question: 1 / 530

During the chemical relaxing process, hair typically undergoes which of the following changes?

It becomes brittle and dry

It shrinks and tightens

It softens and swells

During the chemical relaxing process, hair typically softens and swells. This occurs because the chemical relaxer breaks down the disulfide bonds in the hair's keratin structure. By breaking these bonds, the hair's natural curl pattern is loosened, allowing it to be shaped and styled straighter. The swelling happens as the hair absorbs the relaxer, which can lead to increased manageability and a smoother texture post-treatment.

Understanding this process is crucial for cosmetologists, as it directly affects the hair's health and styling capabilities. Recognizing that hair softens during relaxing helps professionals recommend proper aftercare and moisture replenishment to ensure the hair remains healthy and vibrant.
