Which of the following statements best describes the difference between a perm and a relaxer?

The statement that a perm creates curls or waves while a relaxer straightens the hair accurately captures the primary purpose of each chemical treatment. A perm involves the use of chemical solutions and rods to reshape the hair's structure, resulting in curls or waves, which adds volume or style to straight hair.

On the other hand, a relaxer is specifically formulated to break down the hair's natural curl pattern, resulting in straighter hair. This treatment is often used by individuals with naturally curly or wavy hair who wish to achieve a smoother, more manageable texture.

Understanding this distinction is crucial for anyone working in hair care, as it influences the choice of treatment based on the client’s desired hairstyle. It also helps ensure appropriate product usage and application techniques to maintain hair health and achieve the desired outcome.
