What is the primary result of using thio relaxers?

The primary result of using thio relaxers is soft curl reformation. Thio relaxers work by breaking the disulfide bonds in the hair's protein structure, allowing the hair to be reshaped from its natural pattern, whether that is curly, wavy, or frizzy.

This specific chemical process relaxes the curl pattern of the hair while also allowing for a softer and more manageable texture. It is particularly effective for individuals with wavy or curly hair who desire a smoother, more controlled look without completely straightening their hair.

Other processes such as permanent wave formation typically involve creating curls rather than altering their structure in a softer manner. Color enhancement deals specifically with changing the color of the hair, and hair thickening addresses increasing the hair's volume rather than altering its curl pattern. Thus, the focus of thio relaxers on softening and reforming curls supports the selection of soft curl reformation as the correct answer.
