What is the process involved in using a chemical relaxer?

Using a chemical relaxer involves a specific process that targets the structure of the hair to achieve straightening. The correct process breaks down the disulfide bonds in the hair. These disulfide bonds are strong chemical linkages formed between sulfur atoms in the hair's protein structure (keratin). When a chemical relaxer is applied, it contains active ingredients that penetrate the hair shaft and break these bonds, allowing the hair to be reshaped into a straight form.

This is a critical mechanism because it directly impacts the hair's curl pattern and texture. Once the disulfide bonds are broken, the hair can be styled straight and will remain in this new shape until new hair growth begins or until the bonds are reformed through subsequent treatments.

Understanding this process is vital for anyone in the cosmetology field, as it highlights the importance of both recognizing how chemical relaxers work and the need for proper application techniques and aftercare to maintain the integrity of the hair. The other options do not accurately describe the function of a chemical relaxer; for example, enhancing color vibrancy and promoting hair growth relate to different treatments, and adding volume does not align with the primary purpose of straightening hair.
