1. A relaxer curls hair; a perm straightens hair.

2. A relaxer straightens hair; a perm curls hair.

3. A relaxer adds volume; a perm reduces volume.

4. A relaxer is temporary; a perm is permanent.

The correct answer is: A relaxer straightens hair; a perm curls hair.

The correct answer highlights the fundamental purposes of a chemical relaxer and a perm in hair treatments. A chemical relaxer is specifically designed to straighten curly or wavy hair by breaking down the disulfide bonds in the hair shaft. This process results in hair that is smoother and less frizzy. It effectively reduces the natural curliness, making the hair more manageable and straight. In contrast, a perm, short for permanent wave, involves curling the hair by using a chemical process that also alters the disulfide bonds. A perm introduces curls or waves to straight hair or enhances the curl of already wavy hair. Through this difference in function, the correct answer encapsulates the essential characteristics of each hair treatment type. Relaxers are utilized for straightening, while perms focus on creating or enhancing curls. This is the crux of their respective applications in the beauty industry.
