What is a key benefit of using a relaxer?

The key benefit of using a relaxer is that it creates smooth and straight hair. Relaxers are chemical treatments specifically designed to alter the structure of curly or wavy hair, making it more manageable and easier to style. They work by breaking down the protein bonds in the hair, allowing the hair to be reshaped into a straighter form. This transformation not only reduces frizz but also leads to a sleeker, shinier appearance, which is often sought after by those with naturally curly hair who want a straighter look.

While other options may describe results that some might want from different hair treatments, such as curl definition or added volume, they do not pertain to the primary purpose of relaxers, which is focused on achieving straightness and smoothness in the hair.
