What is the main effect of using a relaxer on curly hair?

The main effect of using a relaxer on curly hair is to straighten and loosen the curl pattern. Relaxers work by breaking the disulfide bonds in the hair, which is the structure responsible for curls. By altering these bonds, relaxers allow the hair to become straighter and smoother, reducing frizz and curl density. This process gives individuals with curly hair an opportunity to achieve a sleeker, more manageable hairstyle for an extended period.

In contrast, the other options do not align with the primary purpose of relaxers. Enhancing curl definition suggests an intention to intensify curls rather than alter them. Adding texture and volume implies creating a fuller appearance, which does not accurately represent the goal of using a relaxer. Lastly, creating waves would suggest promoting some curl or wave pattern rather than minimizing it, which contradicts the effect of a relaxer. Thus, the focus on straightening and loosening curls reflects the true objective and effect of relaxers on curly hair.
