Question: 1 / 400

What is one of the primary uses of a perm solution?

To enhance shine in hair

To break disulfide bonds in hair

A perm solution is specifically formulated to restructure the bonds within the hair, allowing it to take on a new shape or curl pattern. One of the primary uses of a perm solution is to break disulfide bonds in the hair’s keratin structure. These disulfide bonds are responsible for maintaining the hair’s natural shape, and by breaking them, the perm solution enables the hair to be reshaped into curls or waves when combined with a setting rod or exterior shaping method. This chemical process allows for long-lasting results that alter the hair's texture, making a perm one of the most effective ways to achieve curled hairstyles.

In contrast, enhancing shine in hair, cleansing the scalp, or adding volume are not the direct effects of a perm solution. While a perm can contribute to the overall appearance of hair, its primary function is to chemically alter the structure of the hair to create curls or waves.
