What is the function of a relaxer in hair treatment?

A relaxer is specifically designed to alter the structure of curly or wavy hair, making it straighter and smoother. The active ingredients in relaxers work by breaking the disulfide bonds in the hair's protein structure, allowing the hair to become more manageable and reducing frizz. This is particularly beneficial for individuals with tightly coiled or textured hair who desire a straighter look.

In contrast, other options focus on different aspects of hair treatment. Adding volume to hair involves techniques or products that lift the hair at the roots or create fullness, which do not relate to the function of a relaxer. Enhancing color retention deals with maintaining or prolonging hair color, a function that does not intersect with relaxing treatments. Removing unwanted color pertains to color correction methods, which also are not connected to straightening or softening hair textures. Thus, the core function of a relaxer distinctly aligns with softening and straightening curly or wavy hair.
