What is the primary action of a chemical relaxer?

The primary action of a chemical relaxer is to straighten the hair. Chemical relaxers work by altering the hair's structure, breaking down the disulfide bonds in the hair shaft. This process allows the hair to adopt a straighter form, which results in a smoother, sleeker appearance. Relaxers are typically used on curly or wavy hair types to achieve a more manageable and straightened look.

While other options may relate to hair treatment, they do not accurately describe the main function of a chemical relaxer. Waving the hair refers to curling or creating waves, which is contrary to the straightening action of relaxers. Moisturizing hair is a different process aimed at enhancing hydration and shine, and texturizing involves creating definition and movement, not necessarily straightening. Thus, the ability of chemical relaxers to effectively straighten hair makes it clear why this action is the primary purpose of these products.
