What is the role of a relaxer in hairstyling?

The role of a relaxer in hairstyling is primarily to straighten curly or wavy hair. Relaxers work by chemically breaking the disulfide bonds in the hair structure, which are responsible for the curls or waves. By altering these bonds, the hair can be transformed from its natural texture to a straighter appearance. This process allows individuals with naturally curly or wavy hair to achieve a sleek and smooth look, and the effects can last for several weeks or months, depending on the type of relaxer used and the hair's condition.

Other options do not align with the purpose of a relaxer. While coloring agents are used to change hair color, relaxers are not designed for this purpose. Similarly, products aimed at promoting hair growth or creating volume serve different functions altogether and do not provide the straightening effect that relaxers are intended for. Thus, understanding the function of a relaxer is crucial for hairstyling professionals who want to meet the specific needs of clients seeking straight hair.
